    Has anyone had any success with code to use the uPSD as an I2C SLAVE?

    Whatever I try (and I've now tried a lot), I cannot get the uPSD to generate an acknowledge on receipt of a valid control (aka address) byte - Causing the master to indicate a failed transfer.

    I found some example code on the ST web site, but this only included MASTER functionality.

    Was about to give up on this - Then noticed the details of the P3SFS register.

    Once I conditioned the port pins to be used for I2C I started to receive acknowledgements.

    Silly me
