CANcorder

Enterprise CAN tools come with steep learning curves and four-figure price tags. Open-source alternatives cover the basics but often lack protocol decoding or offline analysis. CANcorder bridges that gap: professional features, approachable UI, one-time purchase.

CANcorder's dual-pane layout shows CAN frames and reassembled messages side-by-side. Click a message to highlight its constituent frames — and vice versa.

Live CAN Frame Capture

Connect to your CAN interface and see every frame as it arrives. Virtualized rendering handles tens of thousands of frames without lag.

• Standard (11-bit) and extended (29-bit) arbitration IDs
• CAN FD support with configurable bitrates
• Filter by ID (exact, wildcard, or regex)
• DLC range filtering and frame type toggles
• Click to copy frame data to clipboard
• Shift-click to measure time deltas between frames

Multi-Protocol Message Reassembly

Fragmented multi-frame messages are automatically reassembled and displayed with timing information and direction detection — across seven transport protocols.

• ISO-TP with conventional and extended addressing
• SAE TP2.0 (Volkswagen Group) with dynamic channels
• K-Line transport for serial diagnostics
• J1939 transport (BAM broadcast and RTS/CTS with flow control)
• CCP and XCP calibration protocol decoding
• Bidirectional frame correlation (click to highlight)

Protocol Hints

CANcorder recognizes diagnostic messages and overlays human-readable annotations. Expand any hint to see field names, interpreted values, and raw bytes.

• UDS: 12+ services with DID lookup (VIN, ECU serial, firmware…)
• OBD-II: all modes with PID interpretation (RPM, speed, temp…)
• KWP2000: legacy protocol with best-effort matching
• Color-coded status: request, positive, NRC, busy
• Smart filtering: show only request/response pairs per ECU

Extensible Plugin System

When standard protocols aren't enough, create JSON-based plugins to decode your own vendor-specific services. No compilation needed — just drop a file.

• JSON plugin format with schema validation
• Carrier service wrapping for tunnelled protocols
• Conversation tracking for stateful decoding
• Field formats: hex, decimal, ASCII, version, address
• Built-in example: VehiCAL calibration protocol

CANcorder isn't just a passive logger. Send individual frames, automated sequences, or sweep entire ID ranges — ideal for diagnostics, fuzzing, and ECU development.

Quality Test Panel

Measure the reliability of your CAN link in real time. CANcorder tracks a custom test protocol and reports detailed quality metrics — ideal for validating adapters, cables, and bus configurations before a diagnostic session.

• Packet loss, duplicates, and out-of-order detection
• Latency and jitter analysis (min / avg / max)
• Checksum verification and burst loss reporting
• Pass / fail verdict with color-coded status
• Export results as CSV or JSON

J1939 Live Dashboard

Monitor decoded J1939 parameters in real time. The dashboard decodes PGN payloads into human-readable values and tracks their history with sparkline charts — grouped by source ECU.

• Engine speed, temperatures, pressures, voltages at a glance
• 120-sample sparkline history per field
• Automatic field discovery — only changing values shown
• Color-coded units (RPM, km/h, °C, %, V, kPa)
• Extensible via external J1939db.json catalog

Rare among modern tools — CANcorder handles K-Line (ISO 9141 / ISO 14230) diagnostics via J2534 adapters on Windows. Session init, keepalive, and raw byte capture alongside CAN.

Drag and drop log files from any source. CANcorder auto-detects the format and displays rich metadata including VIN, logger info, and capture timing.

Native drivers on every platform — no generic middleware, no compatibility headaches.

Unique J2534 Bridge Architecture

CANcorder ships as a 64-bit app with a bundled 32-bit bridge process. Legacy 32-bit J2534 DLLs run in an isolated process with IPC, so a misbehaving driver cannot take down the main application.

• Auto-detection of installed J2534 adapters
• 32-bit and 64-bit DLLs supported simultaneously
• Out-of-process isolation for stability
