http://ww1.microchip.com/downloads/en/AppNotes/00554c.pdf I found one archive entry asking a question about the code but nothing about if it works. I'm trying to access an I2C temp chip with a 12F629. Wanted to make sure the Microchip code was good before giving it a big chunk of the program memory. :-) thanks chuckc -- http://www.piclist.com hint: The PICList is archived three different ways.
