    Re: BAT 42

    I've found that BAT43, BAT48 and BAT85 all worked fine in my ICSP.

    I don't know anything about the programmer you mention but I guess they're simply specifying a small signal, fast, Schottky diode.

    If you don't mind a fatter diode then a 1N5818 will probably do.

    I've never tried a 'normal' signal diode, it may work, but no doubt you will messages of doom about them.

    Smile Very Simple ICSP Programmer Working fine with 16F628A

    Hi guys,

    I made the programmer with 3 resistors and using the ICPICPROG 1.0D.
    I was confused with the pins connection between COM port and the PIC IC.
    I connect to 16F628A as below:

    TXD (Pin 3) -----[4.7K]------ MCLR/VPP ( Pin 4)

    GND (Pin 5) ----------------- Vss (Pin 5)

    DTR (Pin 4 ) -----[4.7K]------ RB 7 /PGD (Pin 13)

    CTS (Pin 8) ----------------- RB 7 /PGD (Pin 13)

    RTS (Pin 7) -----[4.7K]------ RB 6 /PGC (Pin 12)

    The ICprog run fine at Windows 98SE.
    Under XP Pro SP2 the program show error : Privileged Instruction...

    How i can use ICprog under XP Pro?

    Install the IC-Prog NT/2000 driver

    The driver can be found HERE

    You should also have a look at WinPIC
