Hello again. 

I had no idea there were so many different ways to do what I wanted. I found about 6 different app notes in the download section, excluding Peter's TROS ducumentation. I feel completely overwhelled with information and I have no idea where to start. The SX circuit that I have now is set up to run at 20 MHz and most of the VP/Dual UART demos all run at 50MHz. Is it easy to change them to 20MHz? I can of course change the FREQ directive, but I cant find any RETI commants to determine how often the interupt would run. Also, I am not really sure where to put my code in the template. 

Basically, what I need is a single UART, one that can send and recive bytes at 31,250 bps.

Also, I need a timer that would set a flag every 1/60 seconds.

Even though there is so many demos and so much documentation, I am having a lot of difficulty implementing this.
