    Default Problem with ICSP & PIC16F628A

    I have a working circuit where i would like to use In-Circuit Serial Programming. I am using MeLABS EPIC Serial Programmer.

    Unfortuanatly, i am not getting very far. I have attached a circuit diagram of the ICSP part (main circuitry not shown).

    The PIC is a 16F628A.

    Has anyone successfully used this combination, if so, what am i doing wrong. Its basically saying the PIC is not detected.

    Many thanks,

    Steve
