Custom UART SerialPort Pin Configuration G400D


#1

I am working with a board I designed using a G400D SoM and I managed to reverse my Tx/Rx connections on my PCB. While I’m going to make changes and get a new revision, I was wondering if there was a “quick and dirty” way to use a UART with reversed RX/TX pins or if anyone had code to implement a custom RS485 Driver in RLP. I know it’s a long shot… but I’m relatively new to the G400D and I’m hoping to glean from some existing experience.

Welcome to the forum.

Depends on what kind of speed you need, you might be able to go away with software UART implementation even using managed code.

@ Architect - Even 9600 would get me by just fine. Do you really think the managed code could do that? 1 bit/104 us? … Seems too fast for managed code. Maybe I’m not giving it enough credit.

xacto knife and bodge wires. Cut the traces and swap them over.
