I think that one reason to use hex to represent a bitmask is that each hex digit is four bits. That makes it easy to translate it to binary when you are troubleshooting later.

Thanks for adding this!

Thank you soo soo much for this video. maybe the most detailed video on this topic on the whole RU-vid. please also make a video on wakeup reason and identify the pin that woke up esp from the deep sleep.

@programmingelectronics 10 месяцев назад

Thanks! And thanks for the video recommendation!

You explained it very well. Thanks

Glad it was helpful!

"Even after you putt it into deep sleep" ... didn't realize I needed golf gear.

One easy way to convert binary to hexadecimal inside your head, without using a calculator, is to group the binary into 4 bits groups, each of the groups can be represented by a hex 0-F. For example: 0b1000=0x8, 0b0000=0x0, 0b0001=0x1, 0b0100=0x4, putting them all together and you get 0x8014

When I want to save data between sleep cycles, I use a struct saved with SPIFFS. You can use this method to save 'current state' data, and setup/configuration data.

Hello, good morning, a long time ago I had problems with the esp32's deep sleep, since when using the RTC the clock would go backwards or forwards or even go crazy, also when you woke it up with some external interruption and it had slept for a long time, It was difficult to wake up, so the device had to be reset. Do you know if these problems have already been solved?

@thenextproblem8001 7 месяцев назад

Can we use a button to wake it up and use the same button after wake up? Can you make a example

@deakcutwinkle 9 месяцев назад

Can I still putt my esp32 to sleep if I don't have golf clubs?

@programmingelectronics 9 месяцев назад

Yes!

@alejandroecheverria1337 4 месяца назад

Se podria uswr un MPU6050 para despertar el ESP32?, como se podría hacer?

@bestofkings9793 8 месяцев назад

if you are working with a smart parking system or something similar you will need to write code in the loop function and find a way to get it to sleep in the loop function based on an event or something, right?

@programmingelectronics 8 месяцев назад

I think there are a lot of ways of doing something like this, but yes, you can always have code in your loop as long as you are not putting the ESP32 to sleep in your setup.

@bestofkings9793 8 месяцев назад

@@programmingelectronics yeah that makes perfect sense, anything after the sleep function wouldn’t run or be executed so yeah that’s cool. Thanks sir. Currently working on something great and big with the knowledge I’m getting online from your channel and others. Today is my 15th day starting arduino though so thanks ✨

I wanted to setup one push button for sleep and wake up but three is so much for me 😅

@giusepearturo 9 месяцев назад

would be super nice if you have a multimeter checking the consumption. :)

@programmingelectronics 9 месяцев назад

Agreed! I hope to release another video showing just that - thanks for the recommendation!

@Pippo.Langstrumpf 10 месяцев назад

Hi. No more live talking?

@programmingelectronics 10 месяцев назад

Not lately... Maybe we'll start it up again some time!

@drboczek 9 месяцев назад

how to detect which button was used to wake up?

@robertherzog2087 8 месяцев назад

I would like to know this as well. I have a project where each button will do something different, so I need to know which was pressed. Your videos are always informative, thank you for them.
