Hello,
to prevent trouble wile adjust CAN filter please check always latest CAN driver documentation. The values "Format" and "Align" has important influence!
Sample:
Filter should accept only 0x300 and 0x301.
- condition for acception refer CAN documentation -> hence: code 0x001, mask 0x301
- default align is "0", results: code 0x10000000, mask 0x80c00000
