I know that the A320 layout maps for the A320 are still in prograss. I myself think that you are doing an amazing job with trying to make the usage of X-Plane 11 with Arduinos very simple! There are some things I noticed I wanted to talk with you about.
The first thing I wanna talk about is the fact that there are some push buttons (Korry) have LEDs which are not accessable with the layout map. For example i have no idea how to use the APU Master SW ON LED...
The second thing I noticed was that the A320 layout has a Seat Belt sign ON - OFF position switch. In the newer airbuses (like the FFA320) there also is an AUTO position. Without that there is no way for me to use that properly.
The last thing is that I am not able to use the switches and stuff from the ADIRS section... It simply doesn't work.
I hope you can help me out with some of those bugs!
