If you're expecting to safely enter the ISR anyways because of the "normal" TMR2 interrupt, there's no reason to expect stack problems just because you're entering the ISR effectively twice as often. And you will LOSE resolution each time you go through the ISR (count more interrupts with a smaller TMR2 scale), you won't get higher resolution. --Andrew _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
