diCAN

diCAN is a free, open-source CAN bus analyser for DSD TECH SH-C3x USB-CAN adapters. It also works with standard CANable 1.0 and 2.0 adapters. Plug in an adapter, pick a bit rate and a bus mode, and you are on the bus.

SUPPORTED ADAPTERS 1. DSD TECH SH-C30x series (SH-C30A/C30G/C30L) 2. DSD TECH SH-C31x series (SH-C31A/C31G) 3. Standard CANable 1.0 and 2.0 adapters 4. Other adapters running Elmue Multiboard 2.5 firmware 5. DSD TECH SH-C32x series (the upgraded version of SH-C31x)

REQUIRES APPLE SILICON diCAN is built for Apple Silicon only. It does not run on Intel Macs. macOS 12 or later.

TWO VIEWS OF THE SAME TRAFFIC - An aggregated table with one row per CAN ID: frame count, period and recently changed payload bytes highlighted. - A raw frame stream, every frame in the order it arrived.

TRANSMIT - A transmit queue with any number of rows, each with its own ID, payload, period and repeat count. - Classic frames, CAN FD, CAN FD with bit-rate switch, and remote frames.

FILTER, RECORD, EXPORT - Host-side id:mask filters, applied to the display. Changing a filter never discards frames already captured. - Record frames to a local database, then export to CSV or PEAK .trc for other tools.

HONEST ABOUT THE ADAPTER IN FRONT OF YOU - diCAN asks the adapter what it can do and offers only that: CAN FD, listen-only and loopback appear only on firmware that supports them. - An adapter that is plugged in but not usable is still listed, with what it is and what to do about it. - A session log records connection events and reports from the adapter.

NINE INTERFACE LANGUAGES English, Simplified Chinese, Traditional Chinese, Japanese, French, German, Spanish, Italian and Portuguese, switched from the menu.

REQUIREMENTS - One of the adapters listed above. - A Mac with Apple Silicon, macOS 12 or later.
