Hi, I have 3 different flight controllers. I am trying to find the mapping between Serial0, Serial1, Serial2 up to Serial9 to the port names written on the board like Telem1,Telem2,GPS etc. I was looking at the ‘hwdef’ file for each flight controller board but there the mapping is between Serial and UART and not the port names written on the board. Does ardupilot do the mapping internally somehow?
Can anyone please help me understand this?
