Code

Here is the code to run on a CircuitPython micro-controller. Written and tested with Version 4.1.

To copy the code to the micro-controller:

cp -a code/modules code/main.py /Volumes/CIRCUITPY/

Modules

• modules/encoder_panel.py: Controls the NeoPixel ring and reads the rotary encoder
• modules/input_selector.py: Controls the input selector hardware
• modules/mdac_attenuator.py: Controls the input attenuator hardware
• modules/volume_control.py: Manages the volume control interface
• modules/input_control.py: Manages the input selector interface
