rotary encoders help arduino mega fsx

hello my name is Henry and I live in Argentina, I have an arduino mega 2560 and 24-pulse encoders, I need a library to work with FSX, which serves to adjust the vor obs 1 and 2, hdg ADF, directional gyro, altimeter , artificial horizon, airspeed and autopilot hdg, thank you for your answers

Hi Henry, not sure if this will help you or not, but check out Arduino Cards & Link2FS. I use encoders with mega 2560 and I'm not at all smart with code. Jim has been a good help with his experiments. Have fun.
