You are making incorrect assumptions above. > What is your recommendation? He already told you, don't ever leave a CMOS input floating. Carefully go thru every pin on the PIC and make sure it's either an output or it's tied low or high. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
