I see from a note I read somewhere that CAN bus wants a nice round number for it's baud rate, and only allows 1.5% error... which means using a 12M or 16M XTAL and dividing down. Sadly I want to run on 3V3 and even 12MHz is outside the safe operating curve at this voltage. Can anyone tell me if I can work happily on a CAN bus with an 8MHz XTAL please? David
