Thanks for the Pro-Tip! I plan on making the matrix PCB with my CNC. I just need to know what pins to hook it up too. I actually don't need all of the buttons and axis. Just more buttons than the stock teensy.
From my newb expriments you can edit and flash in minutes very easily. It's not a pain like flashing HID to Arduino Uno's
I would also like to include some rotary encoders but I haven't figured that out yet.
Well the idea would be to have something like Pointy's slick joystick test tool, but with a tab on it that would allow you to tweak the thing without having to deal with re-uploading firmware to it at all. It would be much more end-user friendly. There's very few cockpit builders out there that want to get drug down the rabbit hole.
