But luck would have it I was playing with i2c yesterday, although that code is fairly hacked and not presentable. I would suggest you look at http://www.microchip.com/forums/tm.aspx?m=66491&mpage=1&key=i2c%2cperipheral%2clibrary&#68717 Two things to note - first is that this is for a dspic (or pic24) but should port over to the pic32 without too much trouble (function names will change, but look at the peripheral lib documentation for clues). Secondly this does not use interrupts, there is an app note from microchip (CE119) about using i2c with eeprom - it uses interrupts, but not directly. Hope that helps.

I'm struggling to get this working so did a search on the web trying to find someone who has done this. Your description of the Micromouse and Quadrature Decoders indicates that you are using the PIC32 with I2C EEPROM. Would you be willing to share a code snippet with me showing how you got the I2C EEPROM working with the PIC32? I would greatly appreciate it. Thanks.
