> Now I just wish I had a PLL to up the internal 4MHz to 16MHz (or even > 8MHz would do). Please Mr Microchip. The 18F1320 has an internal oscillator that can run up to 8MHz. Just don't drive it externally or via PLL with anything faster than 20MHz. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
