acceptance filter problem

Post by ivanobono » Thu 30. Nov 2023, 10:13

hi,
i use pcan view 5.1.1.908 (x64),
in my monitored system i have messages with id:
1F0h (stdId)
14FF0100h
14FF0102h
some id from 580h to 640h (stdid)

i want to receive only messages from 580h to 640h (stdid)

if i set acceptance filter to standard id, from 631 to 631 i receive only the 631 messages (right!)
if i set acceptance filter to standard id, from 580 to 640 i receive 631 messages(right), the 1F0 messages are filtered(right), but i receive 14FF0100h and 14FF0102h (wrong)

it's a bug?

Hi,

no, this is not a bug. But the filter mechanism used in PCAN-View is based on the filter mechanism of the SJA1000 CAN-Controller (using a ACCcode and ACCMask register). And unfortunately a mix of 11 and 29 bit IDs could not be filtered correctly by the hardware. With PCAN-Explorer 6 an additional software filter could be used, to be able to filter even a mix of std. and ext. IDs. PCAN-View don't offer that feature.

regards

Michael.
