Ok, so I'm suing Mobiflight and an arduino to bild my RMP for the A320. I have all the buttons working, active/stby channels, channel switching,and main power on and off working just fine. The issue I'm having is when I select VHF1-3 the led annunciator turns off, instead of on. Is there anyway to reverse the output action or flip the action of the LED to reflect what the sim is doing? I plan to eventually have a full home cockpit for the A320 but I'm using momentary 2p tactile switches for the RMP and they turn off when I push the associated button. Anyway to flip this around?
