Fr. Tom McGahee's Page

Fr. Tom McGahee is a high school electronics teacher who frequently posts on PICLIST. He has written a number of tutorials and code samples that have proven to be quite useful to many people. I've set up this page as a way to help him make these files more widely available. All are free for anyone to use. Please write to me if you have any questions about or problems with this page, or to Fr. Tom (his email address is in the files) if you have questions about the contents of these files and documents. Fr. Tom also has made some of these files available here and here.

Picuart.zip "contains a combination assembly file and turorial that covers all the hairy details of using the built-in UART found in many PIC micros. It appears from the feedback that I have gotten that it works will ALL the MID and HIGH range PIC micros. Even people who already have code up and running should read the comments in the file, as they point out subtle pitfalls that may only rear their heads later on when they make a seemingly innocuous change to their code."
