I'm new to embedded development. I have a line to calculate the divisor to setup a uart. What's weird is I'll pass in 32 for the baudRate and I'll get out garbage for the divisor variable (OxFE01FC10). I'm thinking I might be linking incorrectly or may not have setup memory peripherals correctly but I have no idea where to go. Any help would be greatly appreciated. Thank you unsigned int divisor ...

Brian, I took your post and gave it the correct subject, you get a better chance of answers this way. I can only comment on the Philips LPC2294 and LPC2194, both with 4 CAN channels. Have a close look at the CAN Erratas (not fixed but Philips promised to have fixed devices out in Q2/06). The Erratas are not too much related to a gateway application m

The .ld-file must be updated and the extra address-space added. 2. As soon as the processor wakes up the EMC (...
