Hello @joelhoro

Here's the source code of "M5CamColorRecognition" for M5Camera (A Model). You can change the pin map for your ESP32CAM.

@ajb2k3
Thanks guy

We'll make this kind of device

Gay, Wonderful job, Thank you for your article

@ajb2k3 Really thanks for your reply

@yellowelise
Hope those will help you.

@ajb2k3
Appreciate you!

Is it still error?
I can open my m5f file.

Thanks ajb2k3 !

@ajb2k3 @yellowelise e-ink version smart controller is going on.

@DavMartEs It's better to cut off the power cord of battery.

@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.
