lcockerton62 1:51477fe4851b 2 * Code for identifying address and temperature of DS1820 1-Wire Thermometers by Maxim
lcockerton62 1:51477fe4851b 3 * Uses the DS1820 library written by Michael Hagberg and Fernando Caamaño, with some slight modifications
DasSidG 66:c884fba9eaea 4 * NOTE: THIS IS NOT CURRENTLY BEING USED IN THE BMU CODE AS TEMPERATURE MEASUREMENTS ARE CURRENTLY BEING COLLATED BY A SEPARATE PCB
