    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?
