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 UKposts. please also make a video on wakeup reason and identify the pin that woke up esp from the deep sleep.

@programmingelectronics 7 місяців тому

Thanks! And thanks for the video recommendation!

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

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

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.

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

@bestofkings9793 5 місяців тому

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 5 місяців тому

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 5 місяців тому

@@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 ✨

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?

@giusepearturo 6 місяців тому

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

@programmingelectronics 6 місяців тому

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

@alejandroecheverria1337 Місяць тому

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

@deakcutwinkle 6 місяців тому

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

@programmingelectronics 6 місяців тому

Yes!

@drboczek 6 місяців тому

how to detect which button was used to wake up?

@robertherzog2087 5 місяців тому

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.
