> Wayne, if I remember correctly, left justify the ADC goves 65535 counts, > right justify gives 1024 counts. It's a 10 bit A/D, so either way you only get 1024 counts. When left justified, they will show up in the high 10 bits of the 16 bit value fromed by ADRESH:ADRESL, with the lower bits 0. The highest 16 bit value is therefor FFC0h = 65472. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
