Please follow mikb55 advice and measure the CAN bitrate with your oscilloscope. Pick the narrowest bit. Measure the time and take the inverse to get the bitrate. e.g.,
20 µs -> 20 / 1,000,000 -> 0.00002 s -> 1bit / 0.00002 s = 50,000 kbit/s
Reply #5 E looks like 50-60 kbits/s CAN. It is hard to tell from the picture and the resolution.
Reply #10 looks like 50 kbits/s CAN.
A 16MHz crystal is the only one that allows all CAN standard baudrates to be created by the MCP2515 (and a few in between). The 8MHz allows all CAN standard baudrates up to 500kbits/s to be created.
