Captures everything needed to redeploy the two-display clock (hour on I2C 0x61, minute on I2C 0x63) on a fresh Pi: - Both systemd units (matrix0x61.service, matrix0x63.service) - Deployed Pimoroni script tree, including the local %I (12-hour) clock customization - Vendored upstream sources (ltp305-python, breakout-garden) so restore is fully offline-capable - Boot config snippet enabling I2C - install.sh that wires it all back up idempotently - Inventory doc cross-referencing every live-system path Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Rainbow compass example
Calculates and displays compass heading as an RGB colour around the hue wheel, with North being red, South cyan, East green, and West purple, approximately.
Pre-requisites
This example requires:
- A Pimoroni Breakout Garden
- A Pimoroni LSM303D Motion Sensor Breakout
- A Pimoroni 5x5 RGB Matrix Breakout
Installation
Pop the breakouts into your Breakout Garden, and then run the install.sh
script in the root of this repository with sudo ./install.sh to automagically
install all of the required libraries.
Running this example
To run this example, type ./rainbow-compass.py in the terminal, and then
walk through the calibration steps.
Depending on the orientation of you LSM303D breakout, you can change the
line that says Y = 2 in the raw_heading function to e.g. Y = 1 if
you have the breakout flat rather than vertical.
