So I have a D18B20 tempature sensor that I am trying to use. I downloaded the Dallas Tempature Library from(for some reason can’t post the link. I’m using Miles Burton’s library linked to from the onewire page in the playground). I’ve been trying to run the example program and am getting “Invalid CRC”. Unfortunately I’m not sure where to look for the problem.
I’m running Arduino - 0015 with a USB Arduino Duemilanove with an Atmega 328 processor. All of this on a mac OS x. I have the sensor connected to the 5v and ground and then the bus wire to port 12 with a 4.7k resistor.
