# AutoKanban

A minimal FastAPI webapp for a physical kanban workflow with a 58mm Arduino thermal printer.

> **Tested on macOS, designed for deployment on Raspberry Pi 4 (Raspbian/Debian-based).**

---

## Features

- 📝 Users submit tasks as cards via the web UI
- ✅ Admins approve tasks and print them to a 58mm thermal printer (ESC/POS, Arduino-based)
- 📌 Printed cards are pinned to an analogue kanban board

## Quickstart

### 1. Install system dependencies (Raspberry Pi)

```sh
sudo apt update
sudo apt install python3 python3-venv python3-pip python3-serial
```

### 2. Set up Python environment and install packages

```sh
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
```

### 3. Run the app

```sh
uvicorn app.main:app --reload
```

### 4. Open [http://localhost:8000](http://localhost:8000) in your browser

## Printer Integration

- The app uses `python-escpos` to print to a serial-connected 58mm Arduino thermal printer.
- **On macOS for testing:** Use a USB-serial adapter and check your device path (e.g., `/dev/tty.usbserial-*`).
- **On Raspberry Pi:** Default device is `/dev/ttyUSB0` (update in `app/printer.py` if needed).
- The printer must support ESC/POS commands and be accessible via serial.
- For Arduino-based printers, ensure the correct baudrate (default: 19200) and permissions (`sudo usermod -a -G dialout $USER`).
