    OK

    I've done the idiot checks on the hardware:

    1. +5 from PicKit is going through to the VDD on the PicTail
    2. SDA and SCL are connected to pins 5 and 4 of the MCP3221 and have continuity through to pin 10 and pin 9 of the 16F630.

    Looks like hardware connections are fine!

    P.S. there isn't any chance of the on-board (PicTail) 16c745 keeping the SCL and SDA lines low or otherwise interfering is there?

    That's a good possibility. One way to find out is to just ground the MCLR pin on the 16C745. It should put all the pins into high impeadance state. And, see what happens.<br><br>
