Scampy, I2CREAD and I2CWRITE are PBP "software" routines to emulate I2C operations. You don't need to have MSSP capability in hardware to use them. Infact you can use almost any pin to do the interface.

Dave,
Interesting to know... but wouldn't it be better to use a chip that had an I2C module, rather than rely on software emulation ? Or doen't PBP make use of the physical modules incorporated in various PICs ?
