<![CDATA[Arduino IDE Configuration for Core2]]>I have the following additional boards in my Arduino Preferences:

Do I need any other additional board libraries to successfully compile a Core2 project?

These instructions should be posted as a Core2 Sticky. They would go a long way to provide an outstanding starting point for all the new M5Core2 developers.

that boards URL worked for me.

Here are the steps for the M5Core2 factory test. And yes, I have speaker output and the mic works too.

Note: I am on Ubuntu 20.04

  • Download and install Arduino IDE 1.8.19
  • Run Arduino IDE
  • Open Preferences
  • Open Boards Manager
    • Search for 'M5Stack'
    • Install M5Stack v2.0.1 <-- (if you want to try an earlier version change this to let's say v1.0.8 - then you can copy all the files and skip fixing the sketch)
  • Open Library Manager
    • Search for 'M5Core2'
    • Install M5Core2 v0.1.0 (I selected install M5Core2 only)
  • Save already open Sketch as 'Core2_Factory_test'
  • Close Arduino IDE
  • Copy all M5Core2 factory test files into <home>/Arduino/Core2_Factory_test (except ft6336_fw_updater.cpp - has errors when using v2.0.1)
  • Open Arduino IDE
  • Select Board: 'M5Stack-Core2'
  • Fix Sketch (only needed when using v2.0.1):
    • In Setup():
      • comment out: ft6336_fw_updater();
    • In InitI2SSpakerOrMic():
      • after the line: tx_pin_config.data_in_num = CONFIG_I2S_DATA_IN_PIN;
      • add this line: tx_pin_config.mck_io_num = GPIO_NUM_0;
  • Compile Sketch (ignore warnings)
  • Connect M5Core2
  • Select port
  • Download and Run Sketch

Thanks
Felix
