    Oh my gooood!!!

    fill memory with FF

    Programmer>>Setting
    uncheck auto select memory areas and range
    check EEPROM data

    program your PIC... read it back... you're now in business

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Hi, Steve

    Seems impossible to write FF ( or erase ) to the EEPROM ... I had tried this way too ... memory window just can show his red face !!! no more.

    I think, I have to wait for the 7.02 Release ...

    Have a nice day

    Hi, Everybody

    Here is the answer from Microchip :


    Comments:
    You are correct, regarding SSR19753, even though the PIC16F84A is not mentioned. I have informed the development systems group about this.

    The enhancement to erase EEPROM is planned for MPLAB IDE v7.20.

    Currently:
    Issuing an Erase when the device has been code protected will clear the entire device of data. A Blank Check will state the device is blank
    Programming the entire device with new data will change all memory areas. If for example this data were the reset values, a Blank Check after programming would reflect the device is blank.

    So must we do ...


    Good quiet night to you, folks ...

    Alain
