M5PORT EXPLAIN You can identify the port name and function by its color, red is
PortA(21/22) mainly used for I2C, black is PortB(26/36) which can be used for DA/AD, Singel-bus
communication, Blue is PortC(16/17) can be used for Uart. Correspondingly, most of the M5 Units have
the Port with matched color for specify which port it should go in on the M5Core. Those port
