# LTP-305G live-system inventory

Snapshot of every LTP-305G-related path on `matrixpi` at the time this repo
was created. Use this to spot drift if anything is changed on the live system
without being committed back here.

## Systemd units (root-owned)

- `/etc/systemd/system/matrix0x61.service` — runs `clock.py hour 0x61`
- `/etc/systemd/system/matrix0x63.service` — runs `clock.py minute 0x63`

Both have `WantedBy=multi-user.target` and are `enabled`.

## Deployed scripts (under `dissimulo`)

- `/home/dissimulo/Pimoroni/ltp305/`
  - `docs.html`
  - `uninstall.sh`
  - `examples/bargraph.py`
  - `examples/clock.py` — **locally modified**: `"hour": "%I"` (12-hour) instead of upstream `"%H"`
  - `examples/eyes.py`

## Upstream library checkouts

- `/home/dissimulo/ltp305-python/` — clone of `pimoroni/ltp305-python`, used at install time
- `/home/dissimulo/breakout-garden/` — clone of `pimoroni/breakout-garden`, used for I2C autodetect

## Installed Python package

- `/usr/local/lib/python3.11/dist-packages/ltp305/__init__.py`
- `/usr/local/lib/python3.11/dist-packages/ltp305-0.0.1.dist-info/`

## Boot configuration

- `/boot/firmware/config.txt` contains `dtparam=i2c_arm=on` enabling the I2C bus the modules sit on.

## I2C bus state

`i2cdetect` is not currently installed on this system. Once `i2c-tools` is
installed, expect `0x61` and `0x63` to appear on bus 1 when both LTP-305G
breakouts are connected and powered.
