HMC5843磁强计的测试代码，Atmega8芯片，通过iic协议读取磁强计的数值，通过串口传会-a test code for HMC5843.It can be used to get the data from the HMC5843 and transport it to computer using RS232

Headtracker using sensors: ADXL345 (acc), ITG3200 (gyro), HMC5843 (mag) with data fusion using an extended kalman filter on STM32F10x and data output via USB to PC. Code (sensor reading, filter) written by me. Validated on real hardware.
