unfortunately I need to go over this again I am trying to hook up an I2C A/D converter, and the SDA and SCL lines show a 2K resistor on their example, but the example is using 2.7 to 3.6 vdc supply. So, this can't be what's needed for a 5 vdc supply, can it? thanks -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
