Hi Karen,

Your 12 bits are "really" part of a 16 bit word. I haven't played with the ADUC, because those miserable buggers at Analog devices never sent me the free sample I requested (see where thats got 'em now)

If you load ADHI or whatever into DPH and ADlo into DPL, the DPTR will contain a sixteen bit word to play with with the ascii conversion stuff. It is a good idea to mask off the higher four bits in ADhi, to make sure they are blank.

Do you want to scale or offset your data or just display 0-4095 on the display ?
