On-device test for the Roll pattern using mpremote.
|
|
|
|
Usage (from pico/ dir or project root with adjusted paths):
|
|
|
|
mpremote connect <device> cp src/*.py :
|
|
mpremote connect <device> cp src/patterns/*.py :patterns
|
|
mpremote connect <device> cp lib/*.py :
|
|
mpremote connect <device> cp test/test_roll.py :
|
|
mpremote connect <device> run test_roll.py
|
|
|
|
This script:
|
|
- Instantiates Presets
|
|
- Creates a few in-memory roll presets with different parameters
|
|
- Runs each one for a short time so you can visually compare behaviour
