Setup Pypilot motor controller with MacArthur HAT

[Sailoog]

Ops sorry, you are doing nothing wrong. The code of openplotter-pypilot app assumes that if you enable autopilot mode, /dev/ttyAMA0 (UART0) will be always used. This checking was added because if no serial devices are assigned to pypilot, it will start fighting for all the serial devices even the already configured in other applications. But now with the MacArthur HAT you are forced to use another UART if you are already using UART0 for MAIANA or dAISY.

I will publish a new version of openplotter-pypilot fixing this ASAP (maybe tomorrow). In the meantime you can try adding the device from openplotter-serial app and enable autopilot mode in openplotter-pylot app. If I am not wrong pypilot should start.
