Hi Paul, this seems wrong to me. I think you do NOT have to specify CCD_DATA_PACK8 - this is for 8 bit values - but leave this bit at zero - so you will get all your ten bits in a 16 bit memory address. Also, please recheck your connections. I am not sure they are correct. Look in the VPFE users' guide - there are many examples.
