@spjrc set a timer to call a function after 6-12 houre, then call ESP.restart() from that function.

You can reboot esp32 using ESP.restart();

@meirmark the answer is both, just checked the library it use Wire.h so you only have to use the correct pins in the setup Calle.

@meirmark I code All my M5Stack pruduct using Arduino ide with added M5 support, so the library work for me.

@meirmark Google is your friend, 1st hit:https://github.com/sparkfun/SparkFun_SX1509_Arduino_Library

@babygirl1248 i know you can write special code for the rtc, but have never try.
Each time the esp32 is running, you can update the clock and after doing its job, calculate the time it should sleep to wake up at your selectede time and then make it sleep for that amount of sec.

@babygirl1248 try look at this guide: https://randomnerdtutorials.com/esp32-timer-wake-up-deep-sleep/

@punyviking Core2 use esp32 so Google search "lvgl esp32 arduino" give you some hint, it should be possibel .

@babygirl1248 on the core2 you can play MP3 and WAV files stores in the SD card..

Great work, got it installed, looks nice, now i just need time to Play with it.
