I am having trouble talking to multiple ds18b20 on the same bus. does anyone have any code that will read multiple ds18b20 that i could look at to find out what i'm doing wrong??

As with any 1-Wire device, you need to use the MatchROM instruction and send the serial number to the device in question.· I've attached an older demo program designed for two DS1822 sensors; the code structure should help.
