摘　　要：数字电子罗盘HMR3000在飞行导航系统中的应用,首先判断接收的数据是否为起始位,是则开始采集数据,读取第2位,同时对采集到的数据进行保存,否则继续判断。通信单片机采集数据同时要判断是否为结束标志位,是则进行CRC校验,并对数据进行处理,处理后数据送至指定的存储位置。飞行姿态的数据流向为单向,即传感器将数据送到通信单片机,通信单片机将数据进行处理后写到指定的寄存器中,主单片机通过I2C总线将寄存器中的数据读出。Introduced the application of digital compass HMR3000 in the navigation system of UAV. Firstly judge whether the received data is the start bit or not. If it is the start bit, begin to collect data, read the second bit, and meanwhile conserve the collection data. Whereas continue to judge. The communication single chip collects the data and judges if the data is the terminative sign bit or not. If it is the terminative sign bit, carry on the CRC checkout, process the data and send the data to the appointed position of RAM. The transmission of the flight position data is in one-way. The digital compass sends the data to the communication single chip. The data process by the communication single chip and then write to the register. The main single chip reads the data from the register through I2C.
