>My concern was more that the McGahee paper might not be >up-to-date with newer PICs... I think it is only the newer 18 series devices have the 16 bit SPBRG. My memories of looking at the 16F628 is that it is very similar to the other 16F PICs that the MacGhee code does work on. But the MacGhee code is great for the comments, and even with the newer PICs, by following the comments it is readily modified to deal with the changes. I have a version of the MacGhee code that I made into a module to work with Olin's environment, before Olin released his, and it uses interrupts and Olin's FIFO macros to buffer everything, so I know it works too. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
