Arduino IDE Configuration for Core2

[jdonth]

I have the following additional boards in my Arduino Preferences:
https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json

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

Hello @jdonth

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
  • Add Additional Board Manager URL and Save
    • https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json
• 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

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.

Happy New Year!
