Can PCAN-View acknowledge Can-Bus Messages?

[blipton]

I have a device that transmits Can-Bus data, yet PCAN-View doesn't show the data, only "BUSHEAVY".

With the oscilloscope I see continuous traffic on the bus, so not sure if it's a bit-rate mismatch, or if there needs to be a node that acknowledges otherwise it will continue to send it. The smallest bitwidth that the scope shows is consistent with the bitrate set in PCAN-View.

Does the PEAK-USB device / PCAN-View acknowledge messages or only monitor? What else could cause BUSHEAVY?

Hi,

by default PCAN-View set the acknowldge bit. Only if you set PCAN-View in Listen-Only mode, it will set no ack. But you should see messages in the receive window in both cases, if you have selected the correct bitrate settings.
