Yes the Cricket Thermostat (again)... (RA2 vs T0CKI)?

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.
