CANoptic
CANoptic is a desktop application for working with a CAN bus. It groups frames by arbitration ID, decodes data from a DBC file or from signals you define yourself, plots values in real time, and recognizes CANopen service frames. Frames can be sent once or cyclically, and recorded traffic can be saved as JSONL or Vector ASCII (ASC).

Key advantages
- Real-time monitoring with grouping by ID and changed-byte highlighting
- Data decoding from DBC files and user-defined signals
- Recognition of CANopen service frames
- Charts for up to four signals at the same time
- Single and cyclic frame transmission
- Traffic recording with export to JSONL and ASC
- Passive mode for safe observation of a live bus
