Hello, This is my first message to this group but I read this group with atention for some time. I'm using an Olimex LPC-E2294 board with a cristal of 14.746.000Hz. This gives perfect baud rate for RS232 but I can find a CAN bit timing with no error for some usual bit timings like 125K, 250K, etc. If I go to a 15MHz cristal I have perfect bit timimings in CAN but I have a RS232 error of about 1.67%. Is there a way to have no error in both RS232 and CAN baud rates? If not what's the best choice for the cristal value? I want to have both RS232 and CAN. Thank you. Rui
