M5StackCore2 Can Port A be used as Serial port ?



  • Hi All,

    I am new to m5stack. I just wanted to understand if PORT A on the device can be used as a software serial? If so what is the PORT numbers i need to use? I tried G32 and G33 with no luck.



  • Hello @talktosanjay3

    by default port A is for external I2C; however M5Core2 uses two dedicated GPIOs (32/33) for port A so it should be possible to use it for anything as by default external I2C is not being initialized.

    Can you share the code you tried?

    Thanks
    Felix
