Hello List I was wondering if anybody know something about the internal oscillator frequency of the following chips : PIC12F675 and PIC16F88 In the PIC12F675 data sheets it says 4 MHz Internal Oscillator. With use of OSCCAL register you can change the frequency of the internal oscillator, but how low and how high can it go?? (from 3,5 to 4,5 MHz ??) Any info about the PIC16F88 ? thanks in advance Dimitrios Kapousouz _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus -- http://www.piclist.com#nomail Going offline?
