Factory Test and Microphone example not compiling M5 Stick C Plus (latest version)



  • Line 438 in M5StickCPlus\examples\FactoryTest.ino and line 55 M5StickCPlus\examples\Micophone.ino has a compile error on the line marked ----> below

    i2s_pin_config_t pin_config;
    #if (ESP_IDF_VERSION > ESP_IDF_VERSION_VAL(4, 3, 0))
    --------> pin_config.mck_io_num = I2S_PIN_NO_CHANGE;
    #endif
    pin_config.bck_io_num = I2S_PIN_NO_CHANGE;

    The error is:

  • @bazman Fix is to delete the line! Both the microphone example and the factory test project then work.
