CAN bit timming vs RS232

2006-01-03 by r_goncalves2000

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
