This guide will help you to install Air Player in a Raspberry Pi 4B and configure your aircraft instrument panel in your display.
Is my own guide to run 4 Air Player licenses to control a King Air 200 instruments, 4 displays (Pilot instruments in a 17” display, Copilot on a 15,7”, first 6 Engines instruments in a 7.5” and the rest of the 6 engines instruments in another 7.5 display).You can skip many instructions if you don’t need it. It’s a working example. I help it helps you!
IMPORTANT NOTE: The 4 license's of Air Player in the 4 RPI and the 4 displays are working perfect, but I'm STILL CANNOT get each RPI GPIO's to work on the Air Manager. That is another problem for another time and maybe you all can help on this next time.
