    hi, I have a problem reading and writing eeprom 95040. Here's what I get when tries to read memory:
    "Programmer detected
    VID=0x1209 PID=0x5432

    Firmware version 0.10.0
    Hardware ID: 0.0.1 (18F2550)

    Reading EEPROM ... completed

    EEPROM memory:

    Checksum: 0x0

    End (0,17 s)"

    Eeprom has some data stored in it so it should not give such data.
    Here's what he gets after writing:
    "Writing EEPROM ... completed
    Verifying EEPROM ... completed, 0 errors

    End (23,08 s) 0 errors"

    However, after writing, I have the same reading as the one above. Does the application require any additional settings?

    Did you first verify your hardware with the hardware check?
    Are you using the correct expansion board?
