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>

Spirit level example
This examples emulates a circular spirit level, using the LCD to draw the spirit level and the 3DoF motion sensor to detect orientation.
Pre-requisites
This example requires:
- A Pimoroni Breakout Garden
- A Pimoroni MSA301 3DoF Motion Sensor Breakout
- A Pimoroni 1.3" LCD 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 the libraries to run the I2C breakouts.
For this example you'll need to make sure some additional software is installed:
sudo apt install python3-pil
You'll need to clone and install the library for the 1.3" LCD Breakout as follows:
git clone https://github.com/pimoroni/st7789-python
cd library
sudo python3 setup.py install
This example assumes that you have the LCD plugged into the front slot on the
Breakout Garden HAT, which should also work with the Breakout Garden Mini HAT.
To change it to the back slot, change cs=ST7789.BG_SPI_CS_FRONT to
cs=ST7789.BG_SPI_CS_BACK and backlight=19 to backlight=18` on the line
where the LCD is set up.
Running this example
To run this example, type ./spirit-level.py in the terminal.
It's assumed that you have the MSA301 breakout and LCD breakout lying flat, so your Raspberry Pi or Raspberry Pi Zero will be perpendicular to your flat surface.
