I am using the latest beta of PicoScope program. 6.7.19.2
And noticed the can decoding is not working as expected.
Some info on the scope file.
Probe was differential probe on can-H and can-L more than 20 devices on the bus.
Baudrate 500kbps sample rate 4MS/sec (is the 4MS/sec to slow ?)
Test with the latest release candidate 20 is the same problem of not correctly decoding CAN.
Same sample used as above, also tested with a sample with 10MSamples/sec but same problem.
The anomaly's I am looking for are as shown in below image.
In the above sample a frequency inverter was bringing the CAN bus to its knees, but only during starting of the motor.
Caused by a lose shielding of the motor cable.
You may have better luck with 6.7.21 or later, although some people are having issues with this not detecting the scope. I have seen sensible data except for where there is obvious noise on the signals.
I am surprised that most of the hash doesn't disappear using both CanH and CanL
