Missing channel<>interface documentation #10

Closed JoannaAtZipline closed 1 year ago

JoannaAtZipline commented 1 year ago

When plugged into a host, the ollie presents as either 4 com ports in windows or four /dev/ttyUSB devices in linux. It is unclear which USB device corresponds to which interface (IE: channel A / tty/usb0 -> UART A, channelC -> RS485). It would be so very helpful for information about matching channel to interface

@JoannaAtZipline please refer to the Pinout . On Linux I suggest you install the drivers, and the interface will show up as /dev/ttyXRUSB[0-3]

UARTA/ttyXRUSB0 and UARTB/ttyXRUSB1 are ttl level UARTC/ttyXRUSB2 is RS485 UARTD/ttyXRUSB3 is RS232
