I want to print out the angle in degreese, like 43.1 from this module Triple Axis Magnetometer Breakout - HMC5843 - SEN-09371 - SparkFun Electronics
at the moment it prints out this rotating an whole round when its connected to 5v:
Direction 1: 75
Direction 2: 113
Direction 1: 76
Direction 2: 116
Direction 1: 76
Direction 2: 116
Direction 1: 76
Direction 2: 112
Direction 1: 74
Direction 2: 114
Direction 1: 77
Direction 2: 110
Direction 1: 76
Direction 2: 116
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
Direction 1: 77
Direction 2: 117
3volt gives this
Direction 1: 312
Direction 2: 300
Direction 1: 312
Direction 2: 300
Direction 1: 312
Direction 2: 300
Direction 1: 311
Direction 2: 300
Direction 1: 311
Direction 2: 300
