is there any drawback to running a PIC at full steam ahead? For instance, if I have a 20mHz capable processor, is it more prone to erronious readings at 20mHz? Or is the main reason for going slower for timing delays, as in doing a/d conversions? ----------------------------------------------------------------------- The Pinto Page: www.eng.usf.edu/~shidel Join the Ford Turbo Mailing List! http://www.FindMail.com/list/turbo/ Scott -71 Pinto, stock 2.3 turbo, 13.67@98, radials 8.1@85 1/8th mile on slicks -85 Merkur 13.764@98 on radials&3300lbs!
