How can I see which UART is associated with which SERIAL?
I looked in hwdef file and tried to go from there with a reference in betaflight dump with an old flip32 omnibus f4, but it’s not straight forward.
Thanks
Do you mean this:
| Start Parameter | ArduPilot Serial Port |
|---|---|
| UART -A | SERIAL0 |
| UART -B | SERIAL3 |
| UART -C | SERIAL1 |
| UART -D | SERIAL2 |
| UART -E | SERIAL4 |
| UART -F | SERIAL5 |
UART on boards is usually written as UART-1, 2, 3… here A=1, B=2, etc?
I am not sure if I am answering the correct question…but when you run ardupilot you do like this:
/home/pi/ardurover -A udp:YourTargetIP:14550:bcast -B /dev/serial0
same for SITL
-A is UART A which is Serial 0.
What autopilot are you using? Are you actually using that Omnibus board?
yes yuri, it’s working now though I found by trial and error the right rx serial port (happened to be SERIAL2, mapped to UART1). The reason of my question.
I’m not certain this is the exact board you’re using, but perhaps this will help with any future needs:
