# HC_APTBS

WPF desktop application for controlling a VP44 diesel injection pump test bench.

## Features

- **CAN bus communication** — reads/writes bench sensors (temperature, RPM, flow) via PCAN-Basic at 500 kbps
- **K-Line / KWP2000** — communicates with the VP44 pump ECU via FTDI USB adapter at 9600 bps
- **Automated test sequences** — runs multi-phase tests with PID temperature control
- **PDF reports** — generates test result reports with QuestPDF

## Requirements

- Windows 10/11 (x64)
- [.NET 10 SDK](https://dotnet.microsoft.com/) (version pinned in `global.json`)
- Hardware: PCAN-USB adapter, FTDI USB-to-serial adapter

## Build

```bash
dotnet build -r win-x64
```

Native DLLs (`PCANBasic.dll`, `ftd2xx.dll`) are bundled in `Resources/Native/` and copied to output automatically.
