Baud Rate Can-Bus
PostPosted: Tue Apr 05, 2005 11:56 am     Reply with quote
Hello guys,

I am really fighting with the can-bus.

My PIC 18F258 was working very well. But when I put it into the system, it was made for, it had problems with receiving can-messages. After receiving one to three messages the Can-Error-interrupt-flag has been set time after time.

I think, the baud rate is set wrongly.

Who can help me to find the correct configuration for a can-bus with a 20Mhz crystal and a rate of 500kBit/s? The stability of the system is very important.

I would be very thankful for help. Up to then, pom
