2+
3+
A GUI app that bridges a Kvaser CAN adapter to the DAQ Radio dashboard via WebSocket.
4+
5+
```
6+
Kvaser hardware
7+
| (python-can / Kvaser CANlib)
8+
v
9+
kvaser-bridge (this app)
10+
| JSON over WebSocket
11+
v
12+
DAQ Radio pecan dashboard
13+
```
14+
15+
## Prerequisites
16+
17+
- Python 3.10+
18+
- [Kvaser CANlib SDK](https://kvaser.com/download/)
19+
- tkinter (included with most Python installations)
20+
21+
## Install
22+
23+
```bash
24+
pip install -r requirements.txt
25+
```
26+
27+
## Run
28+
29+
```bash
30+
python src/main.py
31+
```
32+
33+
A small window appears with:
34+
- **Channel** - select which Kvaser CAN channel to use
35+
- **Bitrate** - CAN bus bitrate (default 500k)
36+
- **WS URL** - WebSocket URL of the dashboard (default `ws://localhost:9080`)
37+
- **Start/Stop Bridge** - toggle the connection
38+
39+
Click **Start Bridge** to begin streaming CAN frames to the dashboard.
40+
41+
## Build (standalone binary)

```bash
44+
# Linux
45+
pyinstaller build.spec
46+
47+
# Windows
48+
pyinstaller build.spec
49+
```
50+
