@gachapo What log information did your device print?

@arzaman Thanks. Your seriousness really touched me.

@arzaman The IP5306 which is iic version is customized. The best way for you is to ask saler for a replacement or ask our saler for a new core or iic version IP5306. Sorry for the inconvenience !

Hello @tkb-koki,

How about this example code?

https://github.com/futureshocked/ESP32-For-Busy-People-1/blob/9ede724a862539ae18aad1500426ceb4415d5052/04-070_Interrupt_with_button_and_led/04-070_Interrupt_with_button_and_led.ino

@arzaman Really sorry about that. I do not clearly know your problem.

"-if I disconnect USB using core bottom battery the core stays on and I can do reset with power on again
-if I power off (double click) no change to power on again"

Hello @gachapo

You can download the following example code for your board.

https://github.com/m5stack/Applications-cam

That's the configuration for B Model.

#define PWDN_GPIO_NUM     -1
#define RESET_GPIO_NUM    15
#define XCLK_GPIO_NUM     27
#define SIOD_GPIO_NUM     22
#define SIOC_GPIO_NUM     23

#define Y9_GPIO_NUM       19
#define Y8_GPIO_NUM       36
#define Y7_GPIO_NUM       18
#define Y6_GPIO_NUM       39
#define Y5_GPIO_NUM        5
#define Y4_GPIO_NUM       34
#define Y3_GPIO_NUM       35
#define Y2_GPIO_NUM       32
#define VSYNC_GPIO_NUM    25
#define HREF_GPIO_NUM     26
#define PCLK_GPIO_NUM     21

Hello @akita11

Which version are you using? Here's mine.

Hello @arzaman, In order to confirm that if the IP5306 is IIC version on all CORE you have. It's better to download the following testing code.

@tkb-koki multi-Progress？

@tkb-koki Do you means how to use BUTTON on M5Stack Core?

If I am right, you can refer to the code blow.

#include <M5Stack.h>
// The setup() function runs once each time the micro-controller starts
void setup() {
  // init lcd, serial, but don't init sd card
  M5.begin(true, false, true);
  M5.Lcd.clear(BLACK);
  M5.Lcd.setTextColor(YELLOW);
  M5.Lcd.setTextSize(2);
  M5.Lcd.setCursor(65, 10);
  M5.Lcd.println("Button example");
  M5.Lcd.setCursor(3, 35);
  M5.Lcd.println("Press button B for 700ms");
  M5.Lcd.println("to clear screen.");
  M5.Lcd.setTextColor(RED);
}

// Add the main program code into the continuous loop() function
void loop() {
  M5.update();
 
  // if you want to use Releasefor("was released for"), use .wasReleasefor(int time) below
  if (M5.BtnA.wasReleased()) {
    M5.Lcd.print('A');
  } else if (M5.BtnB.wasReleased()) {
    M5.Lcd.print('B');
  } else if (M5.BtnC.wasReleased()) {
    M5.Lcd.print('C');
  } else if (M5.BtnB.wasReleasefor(700)) {
    M5.Lcd.clear(BLACK);
    M5.Lcd.setCursor(0, 0);
  }

@akita11 Yes, as http://vcc-gnd.com told, use the following code

import machine
machine.lightsleep() 

will enter light sleep mode

@gachapo But, M5Camera A model and B model both own PSRAM chip.

Please take a picture for your camera board.

https://docs.m5stack.com/#/en/unit/m5camera

@gachapo Do you own M5Camera A model and B model? or ESP32CAM?

@lurk_ Because there are SY8089, RT9182 chip between BAT pin and ESP32_VCC, in order to transfer high voltage to 3.3V.

So you need a battery with higher voltage capacity.

@lurk_ Can not supply 3.3V. Please supply the voltage greater than 3.3V.

However, the refresh rate of the M5Stack LCD is not high.

@kees Have a good day.

@arzaman How about BASIC Core boots only with Type-C USB cable without BASIC bottom?

@hackbeere Sorry, We have never had its schematic

https://docs.m5stack.com/#/en/core/m5stickc

@lurk_
This code is only for M5Camera A model.

https://github.com/m5stack/Applications-cam

If you want ESP32CAM to work, need to change this code for being Suitable for ESP32CAM.

Refer to what the README.md told
