    Default 16F84 and I2C bus

    Just came back from a Microchip site and found something interesting.
    I was searching for a small sized chip (8 pins or so) that was capable of I2C communications... well, I found none.
    Just out of curiosity, I punched in 16F84 and it was listed as not having I2C capability either, however I do seem to remember programming such a chip a while back (using MCS) and it "spoke" with an I2C device (RTC) without any problems.

    I'm just curious if the MCS has built-in routines that allowed the F84 to communicate with I2C devices, and if such is the case, can I program just about any PIC to do so as well? I'm mostly interested in using 12F615 or 12F675.

    Thanks

    I think PBP lets you use any two I/O pins of any PIC for I2C.
    You just assign your data and clock ports and go at it...

    Thanks Steve...

    kinda thought so too. It sure opens up more possibilities for chip selection.
