I'm struggling to get this apparently simple TMP102 thermometer chip to respond to I2C reads. I'm using the SparkFun breakout board: http://www.sparkfun.com/products/9418
And working with a 12F675. Just trying to get temperature readings from it, but it is not ACKnowledging the I2Cread commands like this:

I2Cread SDA,SCL,tmpcon,tmpaddr,[temperature.highbyte,temperature.lowbyte]

Anyone used this pesky chip before?
