Rotary Encoders¶
- class pico_synth_sandbox.encoder.Encoder(board, index=0, value_when_pressed=False)[source]¶
Bases:
Task
Use the on-board encoder to control your program with simple function callbacks. Supports increment, decrement, click, double click, and long press actions.
- is_pressed() bool [source]¶
Get the current state of the button pin without debouncing.
- Returns:
state of the button, True = pressed, False = released
- Return type:
bool
- set_click(callback)[source]¶
Set the callback method you would like to be called when the encoder is pressed with a short click (at least 200ms).
- Parameters:
callback (function) – The callback method. No callback parameters are defined.
- set_decrement(callback)[source]¶
Set the callback method you would like to be called when the encoder is decremented (turned left).
- Parameters:
callback (function) – The callback method. No callback parameters are defined.
- set_double_click(callback)[source]¶
Set the callback method you would like to be called when the encoder is pressed with two short clicks.
- Parameters:
callback (function) – The callback method. No callback parameters are defined.
- set_increment(callback)[source]¶
Set the callback method you would like to be called when the encoder is incremented (turned right).
- Parameters:
callback (function) – The callback method. No callback parameters are defined.
