FAIO Multiplexer is an open-source Assistive technology wing for Adafruit Feather boards which enables those with limited or no hand movement to use Adaptive switches as input to operate in multiple input modes.
FAIO Multiplexer USB supports following switch modes:
- Switch Access Mode ( HID Keyboard ) : Teal Led
- Morse Keyboard Mode ( HID Keyboard ) : Purple Led
- Morse Mouse Mode ( HID Mouse ) : Pink Led
- Settings Mode : Orange Led
FAIO Multiplexer Joystick supports following switch modes:
- Mode 1 (Button 1,Button 2,Button 3,Button 4) : Teal Led
- Mode 2 (Button 5,Button 6,Button 7,Button 8) : Pink Led
- Settings Mode : Orange Led
How to change the mode?
You can change the mode by holding switch number 4 or D for 2 seconds.
Additional firmware to operate Xbox Adaptive Controller using switch module is available as well.
These are all the files and documentation associated with the FAIO Multiplexer project.
