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.Options

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
