CANopen Bench: a web UI for testing CANopen devices, built on canopen

[NobseVomBerg]

Hi all,

Sharing a tool built on top of this library: CANopen Bench, a web UI for testing and controlling CANopen devices on a hardware bench.

The canopen package does the heavy lifting: real devices are driven through it, and its EDS importer reads the object dictionaries. The demo mode uses it too, simulating devices from real EDS files, so the whole thing runs without hardware.

On top of that:

• bus scan with identity matching (0x1018) against an EDS registry
• object browser with SDO read/write, favorites and last-known values per serial number
• NMT control and LSS addressing (CiA 305)
• declarative YAML test cases run against the device, with an HTML report per run
• machine control: store the expected bus state, verify it on start, re-address on a mismatch
• live trace decoding SDO/PDO/EMCY against the EDS

pip install canopen-bench
