I'm using ATMega 16 microcontroller. You can find more specifiaction and "how-to" on this link: http://www.x-simulator.de/forum/mjoy16-usb-avr-joystick-t726-70.html#p15777
I dont have HOTAS joystick, I have simple Genius f23, but I want to build on this button box three controlers: one for left engine, one for right engine and one for rudder/wheel. And also I'll install two 8-way hat just for HOTAS.
I didnt fly a lot with A10c just because I didnt have so many buttons, and i found that it's really complicate to remember all keyboard shortcuts or position of buttons when you need to activate something in the flame of battle. Can you make for me a list of most used buttons on a10c (about 50 buttons)? I'll be very gratefull :)
I'll publish all pictures and steps when I start to build this, ofc. And I'm want to help anyone, when I finish it. But for now It's just a project in my head :)
