Welcome to PythonDMCGUI

Custom Python + Kivy GUI to control a Galil machine using DMC.

Requirements

• GCLib: https://www.galil.com/sw/pub/all/rn/gclib.html
• Conda (optional): https://www.anaconda.com/download/success
• Kivy: https://kivy.org/doc/stable/gettingstarted/installation.html
• Python 3.10+

Setup

• conda env create -f environment.yml (run in repo root)
• conda activate dmc
• Install GCLib (x64) and ensure PATH is set

Run

python -m dmccodegui.main

Installation to RasPi

# Install system dependencies
sudo apt update && sudo apt install -y python3-pip python3-dev libgl1-mesa-dev

# 1. Install the GUI package
pip3 install dmccodegui

# 2. Install Galil driver separately  
pip3 install https://www.galil.com/sw/pub/python/gclib-1.0.0-py3-none-any.whl

Run

# After pip installation
dmccodegui

# Or alternatively
python -m dmccodegui.main

## Architecture (Developer Guide)

Layered structure keeps UI responsive and testable:

- `src/dmccodegui/main.py`
  - Loads KV files, builds root, injects `GalilController` and `MachineState` into all screens
  - Hooks controller logging to popup alerts and the message ticker

- `src/dmccodegui/controller.py`
  - `GalilController` API with functions to interface w controller

- `src/dmccodegui/app_state.py`
  - `MachineState` dataclass with pub/sub and a rotating `messages` list for alerts

- `src/dmccodegui/utils/jobs.py`
  - Single worker thread + interval scheduler

- `src/dmccodegui/screens/`
  - This directory holds python logic for each screen

- `src/dmccodegui/ui/`
  - `base.kv`: root layout; custom toolbar; global message ticker row
  - `setup.kv`, `rest.kv`, `start.kv`, `arrays.kv`: per-screen layouts
  - `edges.kv`: KV-only subclasses `EdgePointBScreen`/`EdgePointCScreen` using different arrays
  - `theme.kv`: shared styles



## Tests
```bash
pytest -q

See tests/test_controller.py and tests/test_arrays.py for controller behavior and array round-trips using dummy drivers.

Build for PyPI

pip install build twine
python -m build
twine upload dist/*
