How it works
Debounce the inputs, drive an encoder module, and output a PWM signal for each encoder.
How to test
Twist each encoder and the LEDs attached to the outputs should change in brightness.
By setting the debug port to 0, 1 or 2, the internal value of each encoder is output on the bidirectional outputs.
External hardware
Use 3 digital encoders attached to the first 6 inputs.
IO
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | enc0 a | pwm0 | encoder bit 0 |
| 1 | enc0 b | pwm1 | encoder bit 1 |
| 2 | enc1 a | pwm2 | encoder bit 2 |
| 3 | enc1 b | encoder bit 3 | |
| 4 | enc2 a | encoder bit 4 | |
| 5 | enc2 b | encoder bit 5 | |
| 6 | debug bit 0 | encoder bit 6 | |
| 7 | debug bit 1 | encoder bit 7 |
