Soft UART #12

Switch the Debug Interface to use 2 general IO Pins and implement a 9600 baud Soft Uart

I remmember we did that when working with TX RX on dev board :

And we added GPIO somewhere here :

This is the way how it is connected currently with 2 wires image

Can you please tell which pins on OBC and RS485 to use ?

kodsurf commented 2 years ago

Which pin to use ?

Have to change this in thruster initialization :

Change to what ?

Thruster send byte function I change :

In similar way ?

Hi, I think your comment is releated to the diskussion here. I also described the pin to use for RS485 there.

This issue here is related in implementing a 'Soft UART' This means that code should make the timings to handkle 9600 baud RX and TX pins directly. There are some examples how to do this available but I had no time until now to implement it here......
