M5CAM board in Arduino



  • I am new to the electronic world and I am trying to run a demo code on a M5CAM with the Arduino IDE i just dont know how to manage the board. I guess there is something i need to install but i am really not sure. Any idea how ?


  • M5Stack

    1. install esp32 board in the board manager(before install you need add board url to the perferences. detail you could refer this tutorial :https://docs.m5stack.com/#/en/arduino/arduino_development).

    2. use the esp32 official example for esp32 cam.
      github link:
      https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer



  • Thank you very much it was really helpful !



  • @m5stack i just recently had a problem using the code you provided me, it appears that the sketch is too big. It says "Sketch uses 2053855 bytes (156%) of program storage space. Maximum is 1310720 bytes."
    Is this a problem with my computer ? it is 8 ram and 1tb memory, core i7 7th generation intel processor

    @carol-villegas oh, i forget some detail. you need setup the partition scheme to "No OTA" Tool---> partition scheme-----No OTA



  • @m5stack

    With M5Cam is there a menu config example to make this work correctly. I have tried many configurations and it reboots on load .

    Any suggestions would be great, I have had it working with the firmware you supply but cannot get the menu config working.

    Thanks

    Rebooting...
