I just purchased my first set of exploratory 1-wire goodies from hobby-boards and had good luck getting data values out of Temp Sensor and wow is it fun.

I'm pretty sure I'm connecting to the correct device as you can see from my output below, but I can't seem to get the code to get past this point. For powering the Liquid Crystal Display, I've tried both a 16V 0.9A and a 12V 1.5A power supply (specs say 12-24V is good). Any help/advice anyone has would be much appreciative.
