    EDIT: I finally found Melanie's thread:

    Use variables instead of constants.


    Typical start-up time is 50 ms by the way.

    (sample code from PBP v2.60 manual, bottom p.96)


    Referring to datasheet from here:

    PBP manual says 4K7 pull-up resistors on both I2C lines. The datasheet says 2K2 pull-up resistors.

    PBP supports 100kHz I2C devices up to 8MHz. You need DEFINE I2C_SLOW 1 to run above that.
