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 |
