You will have to change the crystal to get 1Mbit/s with less than 0.5% error as required by Bosch. 14MHz will work. The bit rate calculation is pretty much the same for any CAN controller. Define your tqu, TSEG1 and TSEG2 and you are done. I have not used any baud rate calculation software, but you may be able to find one on the Internet. For my use, I just iterated through all the combinations of bit parameters and picked the bit rate and sample position I wanted. -Bryan -- -- Bryan Armstrong bryan.armstrong-6tN4nzCoH/[email protected] _______________________________________________ TINI mailing list TINI-6tN4nzCoH/[email protected] To UNSUBSCRIBE, edit your profile, or see list archives: http://lists.dalsemi.com/mailman/listinfo/tini
