Encoder technical details
Each encoder detected on the controller is added as a pair of virtual buttons. To avoid conflict with standard game controller buttons, which are in the range from 1 to 128, the virtual encoder buttons are mapped to the range of 1000-1319.
This number is based on the ID of the encoder, assigned automatically in ascending order from 0 to 31, and the direction the encoder is turned in.
For example, for increasing the third encoder on a device (e.g. turning En1 on a STECS Standard clockwise), the button ID would look like this:
| Digit | Meaning | Details | Example |
|---|---|---|---|
| 1 | Prefix | Always 1 | 1 |
| 2 | Encoder ID 1st digit | 10s place | 0 |
| 3 | Encoder ID 2nd digit | 1s place | 2 |
| 4 | Direction | 0: Decrease, 5: Increase | 5 |
The encoder would thus be treated as “Button 1025”.
The mapping between physical movement of the knob and increase/decrease directions is determined by the hardware.
