Thanks for the help guys... I don't think the clock cycles will be much of an issue cuz the only thing it will be doing is keeping track of the encoder at that time. So I don't think changing it would be of much benefit. Hopefully it'll work out. Now I'm having problems with syntax on the serout command that I just ain't getting. It looks EXACTLY like the help file but will not accept it so I'll be back I'm sure cuz the code in C is 997 lines and is only about 50% complete.
