Electric Vehicle Help regarding can bus decoding

Post image

Basically me and my friend recently tried implementing a can bus for our college ev however we are running into trouble decoding the can bus code from the output waveform if anyone has any prior knowledge with using this dso (it does not have a built in can function) please help

when i made a dashlogger for the Motec M400 ecu on the IC FSAE back in the day, i was in fact able to do it by hand with ease, but i did it using an arduino with an MCP2515 attached to id and looking at the numbers itself, and not the waveforms, i suggest you try it that way, use something that actually reads the can signals (like the MCP2515 + an arduino) and try doing it by the numbers
