4. Accessing second UART on M5Stamp-PICO

Accessing second UART on M5Stamp-PICO

  • D

    Is there a way to access a second hardware UART on the M5Stamp-PICO?
    I do not need the SPI port but I do need the UART (and I2C) and uploading code while also using the UART in the application is really inconvenient.
    Any help appreciated.

  • Hello @didier9

    for UART you should be able to use any available GPIO for RX and TX like this:

    Serial2.begin(115200, SERIAL_8N1, <RX>, <TX>);

    for I2C you should be able to use any available GPIO for SDA and SCL like this:

    Wire.begin(<SDA>, <SCL>);

    Thanks
