Unlock progress UI:
- UnlockProgressDialog with dark-themed progress ring, phase indicator, elapsed
time, and cancel/close buttons (non-modal, draggable borderless window)
- UnlockProgressViewModel with event-driven progress tracking via IUnlockService
- Triggers on pump selection (manual or K-Line auto-detect), not test start
UnlockService rewrite:
- Persistent CAN senders that outlive the unlock sequence (StopSenders on pump change)
- Concurrent K-Line fast unlock: awaits session Connected, sends RAM timer shortcut
({02 88 02 03 A8 01 00}), verifies via CAN TestUnlock before skipping wait
- Fix Type 1 verification (Value == 0 means unlocked, was inverted)
K-Line fast unlock support:
- IKwpService.TryFastUnlockAsync / KwpService implementation
Additional features:
- ILocalizationService with ES/EN resource dictionaries and runtime switching
- Safety dialogs: VoltageWarning, OilPumpConfirm, RpmSafetyWarning
- SettingsDialog for app configuration
- BenchService enhancements, ConfigurationService improvements, PDF report updates
- All UI strings localized via DynamicResource

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.
