I just need help with the 'Readtemperature' method.

Thanks

I think I may be close except for the last 7 or so lines. I also don't know what kind of info the alarm will be or what to do with it.

I've separated out the readTemp method here.
Thanks

I haven't used the DS18B20 with a P1 in a while so I dusted off my code and brought it up to match my P2 program. The demo looks like this:

You can read from a specific address, or from one device if it is the only thing connected.

Suggestions

• Use the DS18B20 in 12-bit mode (default)
• Instead of programming the alarm into the DS18B20, just read the temperature every second and compare to your own threshold
