    Well it's easily been the longest project I've worked on, but I've settled on the first version of the Cricket Communicating Thermostat.
    This initial version will use a PIC16F917 with 2.5 digit LCD glass controller.

    I've got one pin left over but can choose between RA2/AN2/Vref- or RA4/T0CKI

    Which would you prefer to have as a USER pin?

    I think RA2, but it's hard to decide. RA4 is pretty useful too.

    I like em both too.

    Maybe this will help.

    RA0 = LM35/34 or Soft I2C SCK
    RA3 = 4.096 or 2.5V vref or Soft I2C SCL

    COMM (will post schematic)
    Options for offboard (xbee, Zigbee) or Onboard MAX485, DS275 (RS232)
    +5
    RA5 SS
    RC4 SDO
    RC5 TX/SCK/SCL
    RC6 RX/SDI/SDA
    GND

    Me too for RA2:). I associate TOCKI as a real pain (i.e. gotcha) when dealing with baseline (12bit) devices.
