Before this fix, StartUnlockIfRequired was called immediately after registering the pump's CAN parameters, before any frames had been decoded. The TestUnlock parameter's zero-initialised Value was interpreted as "unlocked" for Type 1 pumps, causing Phase 1 to be skipped and UnlockCompleted(true) to fire falsely. Changes: - ICanService: add IsPumpAlive property (volatile-backed in PcanAdapter) - PcanAdapter: implement IsPumpAlive; mark _pumpAlive/_benchAlive volatile for safe cross-thread reads - MainViewModel: replace direct StartUnlockIfRequired call with a fire-and-forget WaitForPumpCanThenUnlockAsync that waits for PumpLivenessChanged(true) + 250 ms grace, then invokes unlock on the UI thread; cancellation on pump change or CAN disconnect via _pumpLivenessCts - UnlockService.UnlockAsync: skip Phase 2 state-machine when observer seed already reports unlocked (senders still run to prevent re-lock) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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 (version pinned in
global.json) - Hardware: PCAN-USB adapter, FTDI USB-to-serial adapter
Build
dotnet build -r win-x64
Native DLLs (PCANBasic.dll, ftd2xx.dll) are bundled in Resources/Native/ and copied to output automatically.
