Wow that Picmulticalc is really amazing thanks for referring me to it i will defiantly be using it.
I don't need to use a interrupt. Right now i am using a really long pause 10 sec, so when my battery charges up to 9 volts my led comes on saying the battery is fully charge. Then i have my pause that checks back in ten seconds if my battery is still full or not. The only things i don't like about this process is that for that seconds my pic hangs and all my other operations are on a alt until the 10 seconds is completed. Now i was thinking if i could figure out how to use the hardware timers, my timers could count in the background without affecting my ADC, and LCD etc.

Could anyone clarify this for me and maybe suggest a better way of doing this.

thanks
