I've read that, but i don't totally understand it
Which part are you having trouble with? I'll be happy to explain it.

thats why i wanted some help in getting started, i no timer1 would do what i need, but i don't no how to control timer1
T1CON on the 16F870 only has 6-bits that control the timer. Let me know what you don't understand that's in the data sheet, and I'll do my best to explain it. It would help if you tried a few code examples, and indicated which part you're having trouble with.
