    I have now tested with a 18F6585 chip and it is same problem with this chip.
    The current drawn from each pin on portD is 0.2mA.Total of 1.6mA on portD so there is not to high load on the port.
    So I guess that there is something that I have forgotten to turn off or something.
    Now guys..Please help me!!

    If I use ASM code in Picbasic it works.
    I did like this!!

    Startup:
    asm
    bsf LATD,5
    endasm

    pause 500


    asm
    bcf LATD,5
    endasm

    pause 500

    adcin 1,AN1
    adcin 2,AN2
    adcin 3,AN3
    ADCIN 5,AN4

    goto startup


    end


    WHY does it not work if I simple use HIGH and LOW LATD.5
    Is it a bug in PBP 2.44???
