I'm starting to plan out a delta throttle build, but I'm having a little trouble figuring out what the possible capabilities are. Obviously it supports at least three axes. The build instructions show either three buttons or two buttons and a hat. The Arduino joystick library supports much more than that, so it seems the limiting factor is the board. This is where I'm running into trouble. This will be my first electronics project, so I want to be sure I'm understanding the documentation I'm reading. It looks like the board has 18 input pins, of which nine support analog input. To me, this sounds like it could support three axes and up to six buttons, is that right?
I ran into one joystick build that used a separate I/O board with the Pro Micro so the joystick build could support up to 6 axes and 32 buttons. Is there any reason this wouldn't work for a delta throttle?
