Ardupilot Mega 1280 output/input pins numbering

Posted by Davide Sandonà on January 25, 2016 at 6:44am

Hello all,

I was thinking about the conversion of my old ArduPilot Mega 1280 + Oilspan into a digital level tool.

I need to attach an LCD display: as you know the Arduino LCD library requires 6 digital pins. I was wondering if it's possible to use the output pins for the display.

I've seen Jordi Munoz's servo dancing code, but I'm not sure if that can be of any help because the output pins are referred with AVR code and not with "decimal" number...

Can somebody help me please? :)

    I partially figured it out by looking at the Ardupilot 1280 schematics.

    The output pins are:

    • channel 0: pin 45
    • channel 1: pin 44
    • channel 2: pin 12
    • channel 3: pin 13
    • channel 4: pin 8
    • channel 5: pin 7
    • channel 6: pin 3
    • channel 7: pin 2

    Now I'm able to use the LCD. Though, it would be interesting to know the input channels pins numbering. Frankly, I've lost myself in the schematics...
