# Encoder
|
||
|
|
Add twist control to your keyboard! Volume, zoom, anything you want.
|
||
|
|
|
||
|
|
## Enabling the extension
|
||
|
|
The constructor takes a minimun of 3 arguments: a list of pad_a pins, a list of pad_b pins,
|
||
|
|
and an encoder_map. The encoder_map is modeled after the keymap and works the
|
||
|
|
same way. It should have as many layers as your keymap, and use KC.NO keys for
|
||
|
|
layers that you don't require any action. The encoder supports a velocity mode
|
||
|
|
if you desire to make something for video or sound editing. The direction of
|
||
|
|
increment/decrement can be changed to make sense for the direction the knob is
|
||
|
|
turning by setting the is_inverted flag.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
There is a complete example in the Atreus62 main.py
|
||
|
|
|
||
|
|
Create your special keys:
|
||
|
|
```python
|
||
|
|
Zoom_in = KC.LCTRL(KC.EQUAL)
|
||
|
|
Zoom_out = KC.LCTRL(KC.MINUS)
|
||
|
|
```
|
||
|
|
Create the encoder_map.
|
||
|
|
|
||
|
|
Anatomy of an encoder_map tuple: (increment_key, decrement_key, keys presses per encoder click)
|
||
|
|
|
||
|
|
```python
|
||
|
|
|
||
|
|
# create the encoder map, modeled after the keymap
|
||
|
|
encoder_map = [
|
||
|
|
[
|
||
|
|
# Only 1 encoder is being used, so only one tuple per layer is required
|
||
|
|
# Increment key is volume up, decrement key is volume down, and sends 2
|
||
|
|
# key presses for every "click" felt while turning the encoder.
|
||
|
|
(KC.VOLU,KC.VOLD,2),
|
||
|
|
[
|
||
|
|
# only one key press sent per encoder click
|
||
|
|
(Zoom_in, Zoom_out,1),
|
||
|
|
],
|
||
|
|
[
|
||
|
|
# No action keys sent here, the resolution is a dummy number, to be
|
||
|
|
# removed in the future.
|
||
|
|
(_______,_______,1),#
|
||
|
|
]
|
||
|
|
]
|
||
|
|
|
||
|
|
# create the encoder instance, and pass in a list of pad a pins, a lsit of pad b
|
||
|
|
# pins, and the encoder map created above
|
||
|
|
encoder_ext = EncoderHandler([board.D40],[board.D41], encoder_map)
|
||
|
|
|
||
|
|
# if desired, you can flip the incrfement/decrement direction of the knob by
|
||
|
|
# setting the is_inerted flag to True. If you turn the knob to the right and
|
||
|
|
# the volume goes down, setting this flag will make it go up. It's default
|
||
|
|
# setting is False
|
||
|
|
encoder_ext.encoders[0].is_inverted = True
|
||
|
|
|
||
|
|
# Make sure to add the encoder_ext to the modules list
|
||
|
|
keyboard.modules = [encoder_ext]
|
||
|
|
```
