摘 要
早期的指南针采用了磁化指针和方位盘的组合方式，整个指南针从精度、指示灵敏度、使用寿命上都有一定不足。本系统采用专用的磁场传感器结合高速微控制器（MCU）的电子指南针能有效解决这些问题。
系统采用了磁阻（GMR）传感器采集某一方向磁场强度后通过MCU控制器对其进行处理并显示上传，通过对电子指南针硬件电路和软件程序的分析，阐述了电子指南针基本的工作原理及实现。能够在LCD上根据当前位置显示方位。

-ABSTRACT
Since the early use of a magnetic compass and direction-pointer of the composition, the entire compass from scratch, on the instructions of a certain sensitivity of the defect. Using a dedicated high-speed magnetic sensors with microcontroller (MCU) electronic compass can effectively solve these problems.
The system is designed by the reluctance (GMR) sensors collecting a certain direction through the magnetic field strength after the MCU Controller its judgement will be dealt with the results, through the LCD screen display and can be sent to the MCU s top serial Machine. in the LCD display on the current position of the keyboard and through selective compass upload the data processing.

Description: 周立功指南针模块，电子指南针系统中磁场传感器的磁阻（MR）技术是最佳的解决方法，和现在很多电子指南针还在使用的磁通量闸门传感器相比较，MR技术不需要绕线圈而且可以用IC生产过程（IC-like process）生产，是一个更值得使用的解决方案。由于MR有高灵敏度，它甚至比这个应用范围中的霍尔元件更好。
PHILIPS半导体的KMZ52是一个两维磁场传感器，它是使用磁阻的作用以及其灵敏度和线性来测量微弱的地球磁场，且集成了置位／复位功能以及补偿线圈，这些线圈可以用翻转（flipping）技术消除偏移，用电磁反馈技术消除温度的敏感漂移。 -Weeks meritorious compass module, electronic compass system magnetic field sensor magnetoresistive (MR) technology is the best solution, compared to many electronic compass still using fluxgate sensor the MR technology does not require coil and can be used IC production process (IC-like process) production is a more worthy use solution. Since the MR has high sensitivity, it is even better than a Hall element in the scope of this application. The Philips semiconductor KMZ52 is a two-dimensional magnetic field sensor, it is the reluctance as well as its sensitivity and linearity to measure weak Earth' s magnetic field, and the integration of the set/reset function and the compensation coil, these coils can be used to flip (flipping) technology to eliminate the offset, sensitivity to temperature drift with electromagnetic feedback technology to eliminate.
