    Default Re: 18F4550 programming failed using PICkit4 while verifying "User ID memory"

    I still have one bug; 18F4550 programmed by my PK4 run Blinky at 1/2 speed compared to my U2 USB programmer.

    - leads on my PK4 are just over 6 inches, with gold pins so they connect directly beside the pin.
    - flat cable on my U2 is nearly 3 inches long, and PGC/PGD wires on the breadboard are nearly 3 inches.

    I can't find any spec that says EXACTLY what the max length is for the PK4 leads....?

    Robert


    EDIT: The only reference to lead lengths for the PK4 has a 8pin 6in cable:
