@ -187,3 +187,39 @@ Example:
```
The device version is a BCD (binary coded decimal) value, in the format `MMmr`, so the below value would look like `0x0100` in the generated code. This also means the maximum valid values for each part are `99.9.9`, despite it being a hexadecimal value under the hood.
### Encoders
This section controls the basic [rotary encoder](feature_encoders.md) support.
The following items can be set. Not every value is required.
* `pin_a`
* __Required__. A pad definition
* `pin_b`
* __Required__. B pad definition
* `resolution`
* How many pulses the encoder registers between each detent
Examples:
```json
{
"encoder": {
"rotary": [
{ "pin_a": "B5", "pin_b": "A2" }
]
}
}
```
```json
{
"encoder": {
"rotary": [
{ "pin_a": "B5", "pin_b": "A2", "resolution": 4 }
{ "pin_a": "B6", "pin_b": "A3", "resolution": 2 }
]
}
}
```
