Nie miał dnia sędzia meczu Hiszpania - Maroko, a na jego nieszczęście w poniedziałek kompletnie zawiódł też system wideoweryfikacji
W kilku sytuacjach Ravshan Ermatov nie skorzystał z VAR-u, mimo że powinien. Odtwarzacz wideo wymaga uruchomienia obsługi JavaScript w przeglądarce
- Gów**! - wykrzykiwał po meczu wściekły Nordin Amrabat, rysując w powietrzu symbol VAR-u
Reklama Marokańczycy dwukrotnie prowadzili z Hiszpanami, ale byli mistrzowie świata za każdym razem odrabiali straty
Remis uratowali w doliczonym czasie, kiedy Iago Aspas trafił do bramki w następstwie rzutu rożnego, którego w ogóle nie powinno być, ponieważ wcześniej piłka opuściła boisko
Maroko odpadło z turnieju już wcześniej, jednak chciało wrócić do domu z tarczą
Frustracja w drużynie jest więc ogromna. - Co ja mogę powiedzieć o postawie sędziego? Uważam, że podejmował bardzo złe decyzje, które nas skrzywdziły
Kiedy Gerard Pique zagrał ręką, nie użył VAR-u, choć sytuacja tego wymagała. Wszyscy widzieli, co się stało
Dobrze, że można skorzystać z VAR-u, ale oni tego nie zrobili, choć Pique użył ręki - irytował się kapitan Maroka Mbark Boussoufa
Bez wątpienia Gerardowi Pique upiekło się najbardziej. Nie została też poddana weryfikacji sytuacja z samego początku meczu, kiedy obrońca Barcelony zrobił sanki, czyli wślizg dwiema nogami
Mniej liberalny sędzia mógłby w tej sytuacji pokazać nawet czerwoną kartkę. - To frustrujące
Gol Iago Aspasa został uznany, choć było zagranie ręką Pique, a wcześniej przy tym rzucie rożnym piłka opuściła boisko - żalił się inny z Marokańczyków Nabil Dirar
- Niektóre żółte kartki były słuszne, ale Pique też na nią zasłużył. Przy drugim ich golu piłka wyszła poza boisko
Czy to jest dopuszczalne? - pytał retorycznie selekcjoner reprezentacji Maroka Renard Herve

A Creepy Scary Doll Haunted Our Cabin - Duration: 3:27.
We've been friends for about three years and we decided to go to her cabin last summer.
So it was a date where it was kind of groggy outside it was rainy.
My grandma decided to come in and she said, "Hey guys look what I got."
She had this really old doll which was native and it just gave the creepy like
feeling off of us. We asked her where she got it and she had gone to this weird
kind of garage sale type thing and she bought it off of someone for 60 cents
and the person said that they didn't want it anymore.
She put the doll in bed and tucked it in and give it a kiss and walked away.
We then said that it looked really creepy and I guess might have pissed the doll
off because when her parents and her grandparents went out for bingo the
Wi-Fi went out instantly. We decided to talk about funny things.
I told the weirdest thing happened where we heard a little voice behind us. No, no!
We heard a baby crying first yeah a baby behind the doors and I was like, "Are there any
babies like living around here?" She said, "No!" Then later on we heard scratching
from inside the room like tiny hands like as if it was like maybe a cat
scratching at a door a little freaked out and then we decided to leave the
house and so we went on our bikes and it got to the point where it was really
really cold and we couldn't handle the cold so we had to go back.
Came back, opened the door and we went into the bedroom. She had put, um, a new bra that
she got in a plastic bag on the middle of the bed. When we got back it wasn't there.
We looked around couldn't find it. I looked under the bed, the bra was out of
the bag and under the middle of the bed and then from behind us we hear this low
demonic like, "Yeah." We both looked back and we're like, "Did you hear that?"
We opened the door and we went into the bedroom. The blanket was underneath its
eyes and we had put it completely over. So, it got to point we were like really
freaked out. So she went up to this tree and it was a fake tree
and she said, "I hope nothing happens to this tree I really love this tree."
So my parents ended up coming back and we couldn't sleep that night.
We were so scared and so the next day we woke up, the leaves are all over the
floor and they were scattered which kind of freaked us out. That was the time that
we realized that we pissed that doll off and my grandma loves that doll
and she talks to the doll and to the point where she brushes his hair
and to the point where we went in there my grandma came in and she got really
mad at us and she closed the door on us and told us to never go in there again.

[ ♪ Intro ]
These days, it seems like we're closer than ever to transporting humans around the solar system.
But getting people into space is one thing; keeping them alive is a whole different ball game.
It's the difference between exciting new exploration and just a really expensive way to die.
Among a bunch of other things, one of the most important elements to sustaining life
beyond Earth is making sure we're really well fed.
So far, a lot of thinking has gone into ways to grow food in places like the Moon or Mars,
but those are just single locations in the vast solar system.
What we really need is a cosmic food court capable of feeding us wherever we go.
And for that, we might want to look to the asteroid belt!
All this concern about growing food is necessary because of our pesky friend gravity.
It takes a ton of energy to escape the Earth's gravitational pull, and even with reusable
rockets, getting to space can be pretty pricey.
Take SpaceX's new Falcon Heavy rocket, for instance.
It's among the most efficient rockets today, but pack it full of food for Mars and you'd
be paying more than $5,000 per kilogram.
For a one-off trip, maybe that makes sense, but to settle humans on Mars it would cost
$5,000 per kilogram per person, for the rest of their lives.
That's just not sustainable.
Conveniently, though, it turns out we've solved this problem before, like a lot, — and
with something really simple: seeds.
One obvious example is when Europeans crossed the Atlantic to settle in North America, they
didn't bring a lifetime's worth of food with them.
Instead, they brought the means to create more food once they got there.
They farmed.
In that example, North America already had people who were farming, but it's still
a good tactic for getting food to space!
Once we figure a few things out, this could work for a place like Mars, where settlers
could grow food right on the surface.
But if we sent people to Jupiter's moon Europa or Saturn's moon Titan, things would
get more complicated.
Those trips would last for years, and because of their surface conditions, there'd be
nowhere to farm right when we got there.
That's where asteroids come in.
Since they mostly orbit between Mars and Jupiter, they could be a convenient gateway to the
outer solar system.
They're also a lot smaller than even the Moon, meaning they have dramatically less
gravity to escape, which would greatly reduce the food's cost to ship.
Ceres, which is often considered the largest asteroid, has about 3% of Earth's surface
gravity, and most others have thousands of times less than that.
Most importantly, though, some kinds of asteroids may already contain many of the most important
nutrients for life.
They're called carbonaceous asteroids, or sometimes C-types.
C-types are probably the most common kind of asteroid, but they're remarkably difficult
to study because of their appearance.
They reflect just a tiny percentage of the Sun's light, and probably look more like
coal than whatever you're picturing right now.
I say probably because we haven't really been able to study carbonaceous asteroids
in great detail.
Instead, most of what we think we know about them comes from meteorites called carbonaceous
chondrites, which are likely chips of C-type asteroids.
Based on the name, you might think they're mostly made of carbon.
But they only contain a small percentage of carbon at best, along with nitrogen, potassium,
and phosphorus.
Sounds like fertilizer, doesn't it?
Amazingly, deep inside these meteorites, we've also found evidence of some of the same amino
acids that are inside our bodies, as well as other organic compounds.
To top it all off, some carbonaceous chondrites contain up to 20% of their weight in water.
Some of that was surely absorbed here on Earth, but many meteorites contain evidence suggesting
they formed in the presence of liquid water, too.
These useful elements were even enough for one chemist to grow plants in crushed up meteorites!
But hold your space tractors, because we're not ready to start farming just yet.
Ironically, the main obstacle to growing plants on an asteroid might be one of its main benefits: microgravity.
Space station and Space Shuttle experiments going back decades have tried to grow plants
in zero-g with only limited success.
Even though the plants often grow well, the seeds they produce rarely create a healthy
second generation.
Which is obviously key, if you're looking to set up a long-term farming operation.
But some recent experiments are finding more success, so it's not all bad news.
And, of course, we'd still need to provide the right atmosphere, enough sunlight, and
protection from cosmic radiation, so this is an idea for the long haul.
But if we can get it right, the dividend could be awesome, in the true sense of the word.
One estimate suggests that the total population of C-type asteroids could sustain a billion
humans for the rest of the Sun's lifetime -- no matter where they are.
Fortunately, we're also about to reach an important milestone in all of this.
This summer, Japan's Hayabusa2 spacecraft will reach the asteroid Ryugu, marking the
first time we can properly study a C-type asteroid up close.
What's more, Hayabusa2 will also scoop up a piece of its surface and return the sample
to Earth by late 2020.
So, who knows?
Maybe that could start the clock towards a future fed by asteroids.
Thanks to Blue Apron for sponsoring this video.
And for giving me the confidence to cook pork chops for the first time!
I did not grow up in a cooking house, so even though I like to try new foods, I don't
know how to bring them into being in my kitchen.
And it's a problem because my boyfriend is a really good cook and he'll ask me to
help him season things and I just panic and put a ton of cumin in EVERYTHING.
But the other night I made pork chops with quick pickled cabbage and potato salad with
buttermilk dressing.
Blue Apron recipes are super straightforward and explain everything, so you're learning
to cook while making a really good meal.
And, if you get nervous in the kitchen, like I do, it's really comforting to have those
step-by-step instructions.
I didn't overthink, or over season, anything, and it turned out delicious.

Mundial 2018. Harry Kane nie zagra z Belgią [Wiadomości] - Duration: 2:35.
Selekcjoner reprezentacji Anglii Gareth Southgate otwarcie przyznał się, że nie interesuje go pierwsze miejsce w grupie G
W ostatnim grupowym starciu z reprezentacją Belgii zamierza posadzić na ławce Harry'ego Kane'a i wpuścić rezerwowych
- Harry to nasz kapitan i wie, że trzeba się oszczędzać w takiej imprezie. Zagrają inni - mówi szef angielskiej drużyny
Odtwarzacz wideo wymaga uruchomienia obsługi JavaScript w przeglądarce. Reklama Anglicy nie mieli łatwej przeprawy na początku zmagań w mistrzostwach świata w Rosji
Szczęśliwie pokonali Tunezję 2-1, strzelając gola dopiero w doliczonym czasie gry
W niedzielnym spotkaniu z Panamą wrzucili kolejny bieg i wygrali aż 6-1. Aż trzy gole w Niżnym Nowogrodzie strzelił Harry Kane
Napastnik Tottenhamu ma już na koncie pięć trafień. W angielskiej drużynie zapanował spory optymizm
- Od dawna mówiłem, że nie chcę ustalać celów tej drużyny podczas imprezy w Rosji
Nie chcę wyznaczać moim piłkarzom żadnych limitów. Wciąż czujemy to samo podejście - mówił na konferencji prasowej Gareth Southgate, trener reprezentacji Anglii
- Wiem, że Harry Kane może teraz marzyć o Złotym Bucie dla najskuteczniejszego piłkarza turnieju
Jest teraz na szczycie i każdy kolejny gol dodaje mu dumy. Ale Harry również wie, że drużyna jest najważniejsza
Każda decyzja jest podporządkowana całości. Zawsze próbuję zachować balans w zespole i w meczu z Belgią będzie tak samo
Zagrają inni, równie ważni - dodał Southgate. Angielskie media przewidują, że swoją szansę w składzie dostaną
Danny Welbeck, Phil Jones, Gary Cahill i Trent Alexander-Arnold. Lekarze wciąż czekają na poprawę stanu zdrowia Delle Allego I Kierana Trippiera

[Music] Hello dear students of the channel Fernando K,
Today I'm going to show you a subject which is very important, which is a
business calls Watchdog, but after all What is this business coming to?
Security dog? You see that a dog here is not atoa, watch dog, watch dog means a watchdog
guard. What happens here people, we Let's talk about a problem that occurs
with their microcontrollable circuits I already did a test, I
I left it with ESP8266, with ESP32 and left it on my desk
sending, sending, sending something to the server, One fine day it hangs, why does it hang?
A lot makes a microcontroller crash people, is often an interference
electromagnetic radiation, can be a problem of power supply is not very good, it can
a lot and do the circuit brake.
So that's what happens, that's what I'll talk, here's the montage photo.
of one of the assemblies and I input Is this correct with you guys today?
So let's go! People in order to is a dog will implement the watchdog,
Using an interruption by time, by time, for a while and create a
example to simulate a lock and a watchdog I'll simulate with a little
The moment I trigger the key I go enter an infinite loop and there it will stay as
if I had set up a lock, okay? Good the staff is the next thing to do
if the program is frozen? And how to restart ESP32 without you
You have to reset physically, you will not ctrl + alt + del there right?
Understood? Even more knowing that an endPoint, with an ESP device, it may be
far away, it may be miles away from distance from you and is very
difficult then you have to have this mechanism, so the watchdog is for that, it's
that the translation is here I already told you guard dog and if it locks the
business here it will restart automatically and then we'll explain
how are we going to do it. Good how it works is this I'm not going here
too ... This is a little book, so I write only something,
because if you take the PDF later, you You know what I said here, you go.
remember. On this screen it is important talk here and I put it in red not to
forgetting is because we will use a interruption of time, an interruption
hardware, we will use a timer, a timer own ESP32 and I've been searching the
internet about ESP32 has almost no nothing, almost nobody talking about
interruption, I found it very important from here because
so professional use, let me speak here O
Professional use, people can not give you use a professional circuit micro-
controlled without you using the wacthdog why? Because watchdog it
prevents the system from locking and stays there stopped the eternal understood? So is
necessary to implement in many many cases, it is necessary to implement
watchdog and you will see that it is not difficult, not complicated, I'll explain
here, it's perfectly that or you'll get this piece of source code there and goes
to start using it is logical you have to know the criteria, I will explain that in your
criteria if you take this piece of my
source code and put it on your. So if there's already something working with ESP32
put on the watchdog it will get more stable. Well then here folks have some things,
some lines that are very important, Here I am initializing, I do
control of time, so I get This guy's pointer here, that hw_timer
and I initialize this guy already as NULL
because this guy is the one who will do the interrupt control, then I have a
timer here, that I have to make a timer, a timerBegin ie I play for
inside timer, the result of timerBegin to where i have 0 that is ed,
this zero is not zero time or nothing is a ad, the 80 is the 80 mega-hertz, knows how
config in arduino IDE? If you want a ESP32, because it has mega-hertz and the
ESP32's standard 80 mega-clock in there he multiplies this business
more frequently, but one official is that 80 megahertz you have to
Put this, I tested it, it's true and true. because you are enabling counter
progressive the timerAttachInterrupt, is as follows, it's here
this, function here, the true you have to set the timer You set to stay here and the resetModule
that's the guy who's callback him who function is it that will be called in
when the interruption occurs, which what time is it? What time does the interruption occur? At
time that time blows and I go explain well there in the source code, calm right,
but it's the next is three seconds 3 seconds,
passed these three seconds this function & resetModule here it
will be called. So, what happens? You have timeAlarmWrite
that's where you are setting what? 3 million micro second,
people I even put the 3 million micro second is a thing that three
seconds and true is because this will repeat always or always will tell
up to 3, count up to 3, count up to 3, but until he get up to 3, because so he is an accountant,
this guy is an accountant he is equal to C = C + 1 He's going to count the
time this guy counts the time if that face get to three seconds if he
reach for three seconds "pow" it resets so I can not ... How does this work?
The principle is this how it works? I can not let this timer get to
three seconds, he adds up microsecond by microsecond and goes, goes,
Go, it will arrive one hour, 3 seconds will reset. So why does it reset? It is for
if you can not increase the counter because your program
fought the "But fernando my program caught and how does he know he's going to
reset? Because it is hardware people, this timer is not a software, this timer
he is a physical accountant who has inside the chip understood that? Your program
being stopped, the time of it is rising. TimerAlarmEnable, or
timer enables interruption this is only enable function,
not here, that timerWrite what, that he does? Folks this is not a program, right? I'm
explaining function by function for later inside the program you do not get
lost, but all this is going to do meaning for you the time that people
starts to enter the source code, this does not It's the program yet, I'm just showing you how
is that we use the functions of interruption for time, right?
TimerWrite then I put timer that is that structure that I played there and this 0 ... there yes that
0 is an AID that 0 is a reset, I'm zeroing the accountant, the accountant was there
so many millions of seconds ... now Did he understand that?
B people Now I want you, more or
less with it in my head than I said I watched the video and let's go. This is
our assembly today, one of the assemblies huh?
Where do I have an ESP32, two LEDs, two managers and a push button here, then it's the next, what do I do? That
man over here, he's on a three-timer. seconds ie if I keep tight
less than three seconds it will not restart.
Now if I pass and burst the time of 3 seconds with finger pressing here that
push button what will happen? He goes restart and when it restarts it turns on
this green LED we will see? Look I'm going to keep tight the finger here, three seconds lit the green
Look, it's trashed, okay? What did I do? Everytime I rebound lights the green LED,
but look how interesting, dude that I like this pet, it restarts
Too fast, too fast, huh? So so, here again,
I pressed but I did not hold it? Now I'll hold the green LED will light up and
rebuked, so this is the watchdog already Working, okay? Well this one's personal is
following, it was an assembly I made of a master slave with a BME280, so I'm
sending temperature, humidity, pressure and This guy asks for this one and this one from here.
Send this one and I'm printing on both and here I did the following, I
I put watchdog of five seconds here and five seconds. It means that,
let's suppose that the endpoint hangs, passed, had electromagnetic interference
very big and this guy crashed, so I I'll simulate ... how do I simulate the
locking up I keep holding the inner loop
for five seconds, look, rebounded, restarted and is already sending
he has received and sent I am seeing? So if he had caught, he would
Do you understand the importance of watchdog? It's so much to teach that I should
have taught it here since the beginning. So here's the next one, here
caught, caught. You realize that you've caught on here? Catching can not go, rebounded
ready reducer is already receiving, already asked and already received back, see?
So you can crash here, you can crash here, that he always recovers, this is very
important when you have a device is miles away from
distance but rise above the building, on top of a
roof to stay giving ctrl + alt + del huh? So this here is the watchdog people,
this one is security, all the assembly that you do have to have a watchdog.
This is our montage today. Now that you've watched,
Let's continue here, let's continue. Here I want to give a message,
enter my blog fernandok se sign up with email to receive you have to
Verify your email there you will receive I'll send you an email, you confirm.
There are the following people, me too ... I I created my instagram now, so put it there.
the instagram, put on the screen the my instagram.
I want you to come into my instagram, in my facebook, did you understand? Because now I
I started recording some business, another day, boy. I received,
Dude, I got a st. I'm sleepless, man, I'm done.
sleep as long as I do not program this I do not know, I do not know. So I
ave maria I really like ST and the worst is that I I like ESP32 too.
So you'll like things like that there. far. But understand the instagram,
Facebook. In instagram I will show every time
receive a small plate from china USA I'm going to lay there first
no no instagram and then I want you to accompany, if
You have not subscribed to my channel if you subscribe and click on the bell, give
a jewel if you're liking my Video is good? Come on then, come on.
continue here. Pinout always right? What is my PDF? Booklet
huh? So here's my pinout of ESP32, the assembly that people
Did you see that I also talk about that LoRa then I both put watchdog
here in the assembly, in this simple assembly like ESP32, how much I put on the watchdog,
in the assembly of the ESP32 LoRa which is the same ESP né,
only one more chip, one LoRa chip I've already mentioned this in other videos right?
People the simplicity of the circuit, right? uses of GPIO03, GPIO04 and everyone goes
being happy is not true. So let's go ha ... I remembered one
business, i remembered a deal, The other day, I always said, I stayed
very happy because you look at mine. surprise a lot of people from portugal, put the
the flag here, a lot of people portugal is watching my videos
dude and I was very happy to know that my video crossed the sea
arrived there in portugal and it is very "spin" that right? Does not the Portuguese say that?
very cool, am I using the expression correctly? "Turn" there in
portugal means legal looks like a cool, beautiful thing, I do not know, something like that
so I'm talking like this already, I'm learning some expressions of portugal and a
hug to all our brothers Portuguese who are watching the
our video, my video and then I stayed Very happy, I get back, I get back.
I receive email from portugal I was really happy, even
Angola I already received, because after all we all we speak the same language, with some
difference or other there but it is the same language, We can understand each other, right?
So this is a big hug to you all. Let's go here,
continuing here and here is our program. We will have one each
interaction, we will, power reset our timer and
Let's use that business for that. of the lock button you already saw this on
video there, have watched, so it's a really cool business to us
will do the ESP restart is right?
Now let's start the source code. Here the source code is
here is the following the pinButton, the button I'm putting there,
I have red led, I have a green led I have to
set the pin. On here It's that timer that we defined it.
at start up as null and setup here It's not difficult, is not it, the thing is simple
until, I have serial.begin, there logic has pullup no input_pullup
because it's the button I'm going to tighten there you are
Red LED, green LED right? They have to be output right? Then I'll give you a delay.
500 milliseconds and then I do? I give a timerBegin to where?
This 0 is not an accountant 0 people, this one what is it? It's a timerID! Why is that?
timerID Fernando? Because if you want you can use four timers
You can pick up a timer every 2 Microsecond looks cool, the
every 2 microseconds I want to generate a wave, it generates a wave there with a timer,
so long, I want to do such a thing you can because you have a
control at the microsecond level, it is need? You need this business, you must,
you can trust it here. Division by 80, because it is 80 megahertz and
true it's because you're giving an okay on that guy. The timerAttachInterrupt you are passing the
timer, you already set this guy in there above, the callback function that is resetModule and
true because you're enabling this guy also and timerAlarmWrite because here
Write could be SET, could be timerAlarmSET, but I do not know what the guy wanted and put
Write, beauty same thing the structure of the timer there, 3 million microseconds that is
three seconds, I put it here also true because you're putting this in
as being true. TimerAlarmEnable hence I already agree with this writing and
I'm passing the timer argument right? Because I am enabled, from
from here this guy starts to work, only the from this Enable here, there is the following
what I do? Soon after I do the green LED
blink I give it a light on it.
he waits a second and erases, so much is that When he rebels he passes through here, then
the green LED lights up you saw in the video there the led green, did not they see? So that's all,
It's a simple thing, people. Here in the loop, now that the guy is going to stay all
repeating time, thank God it all fit into a screen, our face I love, that's why I do
code, think if I loop that has ten pages of loop you are
fried to understand this business Why do I even have to change the screen?
every time is complicated, so I always I do the programinha pequinhoininho so
What is didactic, right? I'll even make a comment here, let me do it
comment is the following face you've seen what the hell
when you take a code ... get one source code that is there in github
of a complicated trick, picks up the LoraOne protocol that is in github, wants to see
other business GRBL né for arduino there you take there face
Then you start trying to understand that business. giant code, huge code a lot of file
and such, what's wrong with that? You're not dumb, are not you, if you do not
you see stay calm you will not go to sleep
because of this, already noticed all you go on github and picks up a closed deal, who see a deal,
the firmware of a 3D printer, almost face nobody understands that "bagasse" there, but knows
because? The guy did not start doing the source code with 5,000 lines, with 10,000
line, he started with a program small, then it was increasing
increasing, increasing, increasing there is a business that has 20 thousand lines there,
complex, You go there to try to understand and not
Can you understand and what are you dumb? It is not! It is not! You know what this is, because the
complexity ... the guy started small and was increasing, increasing, increasing,
increasing, even these guys later, they other source codes in github and
they do not understand the other day I talked with a face
"I could not understand encryption algorithm, I did everything from
new Fernando, all over again I implemented everything again
I could not understand what the guy did there in the github there in encryption
there the guy took it and implemented it all over again,
Do you understand that? So stay calm. if you do not understand this lot of source code,
program soon so, because the guy presents everything in a single step, then you go crazy, but
It's not you, what's the problem, do you understand? O problem is that there is no didactic
look at a code made once its only, we know that the documentation you have
these guys over there github of life that faces "pindura" code
source there, there is no documentation, but neither a powerPoint
with the diagram does not have ne? Complicated that right? I think it was an outburst, this was broken because I too
I get code also in github that I do not understand, it's a hell not understand code and sometimes it is not because there is that
because the guy wrote the 3D printer code there, which is well done no, it is not! I get a lot, very, very, poorly written, but it works,
Everybody uses understood? There's a lot like this, there's a lot
thing in the world. Good continuing here people,
the first thing I do then, timerWrite, I count zero, first thing
I have to clear the counter, After what I do, I'll take the
current size, I get the current size ... sorry,
second thing I do here I get the current time, the initial time of the
loop, then what do I do here? I I check in this while line here,
digitalRead, I'm reading the pin and I'm Wondering if I'm squeezing the
button, because if I push the button, if I stay pushing the button it will stay
stuck in this tie and detail stuck in this loop is logical I give serial.println
that I am pressing the button and the digitalWrite the
the red LED I will turn on the LED red
I keep it 500 milliseconds on né and I continue my loop, if I take the
finger I can get out of this loop, I'm still going keep another second this guy here,
I'll turn red and then I'll put so "time spent inside the loop
milliseconds " Because? I took the time, because I got the
time up there and then I get the time down here are you seeing? I'll get the
current time minus the time I had taken up there, give me the amount of
time I got stuck there, so I give serial.println in this timer,
here in that time and after I do I turn off the red led and there it goes
so my loop, this way this while here, what does this while do?
It simulates your program crashed! It is logical that a program sometimes hangs and
does not mean that he got into a loop at Sometimes he caught, caught; an instruction pointer
there the "guy" is there everything "ragged" does not know nor where it goes,
does not always mean that he is in the loop, but the loop simulates a
blocking, because when locking happens the moment it crashes?
It prevents the timer from being reset, the team counter is reset, it goes
increasing, increasing, increasing, increasing, arrived at 3 seconds, he speaks ready now I
rebound, callback callback, callback function callback are you understanding?
So folks this is business here, so so logic and there is a business
Let's suppose, now you have a business. important that I have to talk,
let's suppose you have there a lot of thing you're doing in your
program there and you take more than three seconds then your time can ... your
Time burst can not be three seconds and let's assume another situation
that you do business very fast and you do not need to make a burst
of the time of a second can suddenly have a time overflow for example
200 milliseconds will then depend, this time here depends on your program,
then there are applications whose time It's very fast, it does not have to be the order.
seconds, was that clear? Depends on your application, okay? So let's go
over there, now we still have ground here, still
There's a LoRa business I'm going to talk about. People there are the following, right?
here the callback function reminds me that I already Did I tell you about this guy here, too? When you
puts this IRAM_ATTR this callback function, it is allocated in the
memory in a way that it calls Too fast, okay? So this here is a
issue of optimization. Ets_printf the same thing as printf tai I do not
I do not even know why I used this function here, I think To explain to you that you have her.
Also, here it is in this guy here in esp_restart_noos here you
restarts, here it resets in fact the ESP32 understood? I'm so sorry.
it's super simple, here people are the next time, to shoot the computer I
I thought it was not didactic, here a example of ESP32, where I turn it on, I
I call it, it does a lot of startup there after what happens? It's running here.
running setup is running and then he is in the loop to each one according to him
print loop here right, then what happens? I pressed the
button, at which I pressed the button it starts the counter and makes 0 500ms,
1 second, 1 second and a half, two seconds, two seconds and a half, 3 seconds "pow" burst.
Burst the time because I kept holding more of three seconds, look at the three here right? 3
second, here it happens, in that this guy will restart, then reboot and
appears a bunch of hexadecimal numbers of new and then it all starts over again
that's right? So here's to see for this place here. See if you can
increase here, it's terrible when you have small letter I do not think
didactic but I did not find another way to do this business here.
Here it's the same thing, here is as follows, holding down the
less than three seconds, so for example I rebutted, no, I started it, it was there, I called, I called, I called
I pressed the button, but here I I pressed the button and instead of
button when it gave a second I let go, I let out "pimba" what happened? When
I let it go, it was 2,500 milliseconds, it was close to locking
But I let it go, then he continued on loop, continued in the loop there it did not have the
treatment did not have to rebound, then situation here is ... there the first screen it
The 3 seconds burst, here he does not I told you before, did you understand? I wanted to
you understand the simple logic and It was here at 2500
milliseconds is fine. Now it's the following recalls in the video I showed
both, the two ESP32 LoRa a trading card
with the other there, BME280 né the endpoint so it's important that you
watch this video and understand the there because that's where I did
on here? I include the watchdog inside ... Because dude think about it, you have two lora
talking, you think this guy is not going to lock up
You think? Imagine the following you take and places in the middle of the pasture, a business
with the battery, you think this guy does not will lock
He will lock my friend! It is certain that Do you have any life that this guy is going to?
to brake so you have to have the wacthdog
connected on it, the other day I bought a Chinese radio of 5 watts, dude, have you seen 5Watts LoRa? Chinese
It makes a crazy deal right? Radio 5Watts LoRa is not LP ONE nor
here in China, where they did radio, have you thought of that?
But anyway the guys did I'm here in Brazil I I do not know, I'm going to record this video, 5 watts
1 watt but not lp one is not it not low power understood? It is not!
It's not low power anymore, understand? But Finally let me come back, let me go back, let's go back
here, watch this video here it is important.
Well then, let's go people now, now it's the next to implement whatchdog in the project, what we
let's do it? In the file ... remember that on here? Whoever watched the video remembers him,
LoRaSendReceiveBME280.im, what do you will do in it? You will add this
source code, people look there timer = NULL the people callback function, the
callback function, here we will have it, function that sets the timer,
I have already explained, the timerBegin, the timerAttach, the timerAlarmWhite
could be SET but they put it the name Write, timerAlarmEnable, beauty enabled and everyone
Go be happy. You start the serial and here you
calls all warm functions and set Whatchdog, which was a function
what did we do and people here? has timerWrite and the timer,
The timer you reset here is at that time. But when you zero ... Fernando when that
I zero my timer? It depends! You have to have a notion, do the following go with milles there, go
how much your principal bond spends, "to Fernando I My Head Tie It
is spending around 400ms. Beauty then put a burst
of 600 ms, cololoca one more time, one more time. You have security, 600ml
if you are sure the time maximum of your loop is 400ms. 400,
400ms you put 600, for you to have a margin understood? But it depends
much of the ... if you're messing with engine step, if you're messing with telekom,
you have great timeout time, everything This you have to analyze, why? Because
you have to keep clearing this counter, this little devil of that accountant there, I should not have
spoken of devil right? Anyway, good people look, it was not so
It's complicated, is not it? Was not, it was not, I do not know why I did not say that
matter before people are so important. But you You know why I did not? Because I do not
I could record two more videos for because you do not even have time to prepare
the "heck" of the video. Then it's the following
I want to thank the comments again cool fantastic that you are me
sending and until the next video [Music]

✅ Das "Bachelor"-Traumpaar Clea-Lacy Juhn und Sebastian Pannek gab Mitte Juni seine Trennung bekannt - Duration: 1:57.
Clea-Lacy Juhn & Sebastian Pannek: Plötzliches Liebes-Aus! Ihr Liebes-Aus kam völlig unerwartet: Nach anderthalb Jahren Beziehung geht das „Bachelor"-Traumpaar Sebastian Pannek und Clea-Lacy Juhn nun getrennte Wege
Am Donnerstag, 21. Juni, machten sie ihr Liebes-Aus auf Instagram offiziell. so das Statement der 27-Jährigen. Erstes Posting nach der Trennung Nach der überraschenden Trennung wurde es für kurze Zeit ruhig um die beiden
Bis jetzt! Denn Clea-Lacy meldete sich am Montagabend, 25. Juni, nun endlich bei ihren Fans
„M wie Monday Blues! Die meisten Menschen mögen keine Montage. Wie sieht das bei euch aus?", beginnt die Halbbrasilianerin ihr Posting auf Instagram
Doch dann geht die hübsche Brünette auch auf die Trennung ein, wenn auch nur indirekt: DAS steckt hinter dem Liebes-Aus des Bachelor-Paares Wie lange Basti und Clea schon getrennt sind, ist nicht bekannt
Allerdings spekulierten die Fans schon seit mehreren Wochen, dass es zwischen den beiden kriseln könnte
Der Grund: Seit Wochen gab es keine Pärchenfotos mehr von den beiden. Hat den beiden vielleicht die räumliche Trennung das Genick gebrochen? Nur wenige Monate, nachdem die zwei in Köln zusammengezogen waren, löste das Paar die gemeinsame Wohnung wieder auf
Clea-Lacy ging nach Baden-Baden zu ihrer Familie zurück, während Sebastian in Köln blieb. Like OK! bei Facebook und verpasse keine Star-News

Petra Janů: Mám čtyři nové chlapy, dávají mi energii - Duration: 8:05.
Máte kolem sebe nové muže. Že by výběr vé řízení na partnera?Nene, kdepak. Mně e dobře tak, jak to mám teď
Co se týče chlapů, kteří se teď v posle ní době kolem mě hemží, to je má nová ka ela Amsterdam
Jsou mladší a hrají krásně. Přiznám se, že je mi s nimi dobře. Takže vlastně ano mám nové čtyři chlapy
A co opravdoví nápadníci. Točí se kolem vás?Prozatím si užívám přítomnosti mužů kapely, ale jen ryze v pracovní a přáte ské rovině
Každý má svou rodinu a já opravdu chlap nehledám. Na druhou stranu bych lhala, dybych řekla, že mě vůbec nezajímají
Muže miluji. Takže chlapi: Ahoj, mám vá hrozně ráda! Když nějakého potkám, potk m, když nepotkám, nepotkám
Roční období je na to příznivé. Pomalu ončí zima, začíná jaro a s ním třeba i n vá láska
I tak se to může třeba vzít. Ostatně já aro miluji. Právě v zimě dost trpím. Jse totiž Štír, co potřebuje teplo
A jakmile v březnu začne ten teplejší v třík a začne se příroda probouzet, tak o ívám i já
Jako ta kytka. Když se vrátíme ke kapel . Co vás vedlo k tomu spojit se s novou kupinou?Napadlo to Romana Štefla, který ro mě v devadesátých letech produkoval d sku Album
Amsterdam kdysi dávno doprovázel i Ilon Csákovou, pak se kluci rozutekli a po l tech zase sešli
Ve výběru možných adeptek na zpěvačku j em jim tak nějak vypadla já. Mě se ten n pad docela zamlouval
Přišla jsem za nimi na zkoušku, zazpíva a pár písniček a byla ruka v rukávu. Roz odně jsem udělala dobře
Na koncerty s nimi se těším, moc mě to aví. Kluci mi dávají energii. Aby také n , proti mně to jsou všichni mladí kluci, plní elánu
Hrajete společně i jinou muziku, než na jakou jsme u vás zvyklí?V repertoáru mám všechny písničky, které ode mě lidi cht jí slyšet
Je pravda, že mají zlehka nový kabát. V seznamu je i pár, myslím si, neoprávněně opomenutých písní
Teď připravujeme jednu starou písničku, kterou nově nazpívám já. Lidi ji znají a jmenuje se Ještě pár slov mám
Většinou, když do kapely přijde žena, ůže dojít k rozpadu. Nebojíte se toho?Vů ec
Nikdo si nehraje na kápa, vládne mezi n mi velká demokracie. Pokud je třeba dát ěčemu řád, od toho máme naši manažerku, terá, když se něco hrotí, tak to uhladí
Petra Janů a její nová kapela Amsterdam A jsou na vás ti vaši kluci hodní?Chovaj se ke mně krásně
Tak ono taky, když vidí starší dámu, js u galantní. Rodiče je vychovali k úctě k stáří, to je vidět (smích)
Vy ale vůbec nevypadáte jako starší dám . To moc děkuji za lichotku, od ženy to otěší ještě víc
Nic není zadarmo. Určitá genetika asi f nguje. Pokud člověk chce a v mém případě i musí vypadat, aby se mě fanoušci nelek i, musí něco dělat
Já se snažím pravidelně cvičit. Miluji ohyb a už bych si nedokázala bez něj živ t představit
Navíc jsem najela opravdu na zdravý živ tní styl. Neříkám, že bych si občas neda a nic nezdravého, ale dodržuji určitou ž votosprávu, která spočívá především v pr videlnosti stravování
To se bohužel občas nestíhá, takže mám akové pytlíčky, kde se nachází proteinov prášek, který umí zázraky
Jsou to různé polévky nebo i tyčinky, k ktejly. No a díky tomu sem tam přebytečn kilo shodím
V posledních letech se celkem rozmohlo sportovat za dozoru trenéra. Jak to máte vy?I já mám ve fitness trenérku Zuzanku třikrát týdně mě dozoruje
Ostatní dny se pak koukám na televizi, le vždy při tom cvičím. Od třiceti let u prostě hlídám každé deko
Za ta léta to mám už vychytaný.
