# UC2‑Python Client

Python interface to the **UC2 REST** micro‑controller firmware — control motors, lasers, LED matrices, galvos and more over USB‑Serial or Wi‑Fi from any Python environment.

## Highlights

- **Plug‑and‑play connection** via USB (`/dev/ttyUSB*`, `COM*`) or TCP (`host`, `port`).
- **Rich device model**: every hardware block is a Python object with high‑level helpers (e.g. `motor.move_x`, `led.setPattern`, `laser.set_laser`).
- **Asynchronous & blocking modes** for precise timing or maximum throughput.
- **Callback hooks** to react to hardware feedback in real time.
- **Runs everywhere**: desktop Python, headless Raspberry Pi, or in‑browser with PyScript.
- **LGPL‑3.0‑or‑later** license – use it in academic and commercial projects.

## Installation

```bash
pip install uc2rest           # latest release
# or for the bleeding‑edge version
pip install git+https://github.com/openUC2/UC2-REST.git#subdirectory=PYTHON
```

Dependencies (`requests`, `numpy`, `pyserial`) are resolved automatically.

## Quick start

```python
import uc2rest

# USB example
esp = uc2rest.UC2Client(serialport="/dev/ttyUSB0")         # Linux / Mac OS
# esp = uc2rest.UC2Client(serialport="COM3")               # Windows
# Wi‑Fi example
# esp = uc2rest.UC2Client(host="192.168.4.1", port=31950)

# LED matrix: switch all pixels on at half intensity
esp.led.setAll(True, intensity=128)

# Move X axis by 1 mm (1000 steps @ 1 kHz)
esp.motor.move_x(steps=1000, speed=1000, is_blocking=True)

# Turn green laser to full power
esp.laser.set_laser(channel="G", value=255)
```

| `message`       | Generic key‑value messaging/trigger   | `register_callback`, `trigger_message` |

## Design philosophy

UC2 REST splits interaction into three JSON endpoints per device:

```
/*_act   → perform an action   (e.g. move)
/*_set   → configure a device  (e.g. speed)
/*_get   → query state         (e.g. position)
```

The Python client wraps those endpoints so you rarely deal with raw JSON.


## Running in a browser (PyScript)

```html
<py-config>
  packages = ["uc2rest"]
</py-config>
<py-script>
  from uc2rest import UC2Client
  esp = UC2Client(SerialManager=pyserial_manager)  # see docs
  esp.led.setAll(True)
</py-script>
```

## Documentation & examples

* Example scripts: `examples/` directory (motor scan, laser modulation, timelapse)  
* Firmware sources and hardware guides: <https://github.com/openUC2>

## Troubleshooting

| Symptom                      | Fix |
|------------------------------|-----|
| `serial.serialutil.SerialException` | Check port name and permissions (`sudo adduser $USER dialout`) |
| No JSON response / timeout   | Increase `timeout` argument; verify baud rate matches firmware |
