If you're not using it, then its calibration value doesn't matter. As for how to make the PIC run from the timer 1 oscillator, I don't remember off the top of my head. Read the manual. Take a close look at the config bits. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
