I would like to keep it as simple as possible. I see ultimarc has a uhid nano that is small and inexpensive. It says it has only 8 I/o, but that should be enough for my application.
Yes, 8 I/O pins plus a ground pin. (9 pins total)
Based on what you've posted in this thread like you'll need pins for:
- Ground
- 5v (split to power both the steering wheel optical board and gas pedal potentiometer)
- Data Line A (steering wheel)
- Data Line B (steering wheel)
- Analog wiper (gas pedal pot)
- Shifter microswitch (configure as a gamepad button)
- Coin microswitch (configure as a gamepad button or keystroke)
- Exit button, assuming you want to run more than one game on this cab (configure as an ESC keystroke)
- One other input for whatever else you want/need based on your game list . . . you
have already compiled a game list, right? (step 2 of the design process in the FAQ's
What type of build meets my needs? section)
Which FE are you going to use?
- Depending on which FE you choose, you can probably navigate using the steering wheel to move up/down and press the gas pedal to launch the game.
- Howard made the Checkered Flag FE.

Sounds good.
