Decoding CAN

Post by travlytle » Thu Apr 11, 2019 2:16 pm

It took some tinkering but I was able to decode CAN, but I don't see the signals in the waveform window. If I have a vector CAN tool connected it works as you can see in the attachment. If I disconnect the vector CAN tool, I can see the waveforms, but the decoding of the CAN messages is incorrect. I don't blame the picoscope, but I'm trying to understand why I'm having this issue. I do have this on a bench with very short cable and 1 120ohm resistor, but I don't understand why making the Vector tool CAN active on the canbus would stop the picoscope from working.

can you post a .psdata file (upload it somewhere)
O and use a higher sample rate by setting the 1MS on top to 10 or 100 MS
