摘要：早期的指南針采用了磁化指針和方位盤(pán)的組合方式，整個(gè)指南針從便攜性、指示靈敏度上都有一定不足。本系統(tǒng)采用專(zhuān)用的磁場(chǎng)傳感器結(jié)合高速微控制器（MCU）的電子指南針能有效解決這些問(wèn)題。 系統(tǒng)采用了磁阻傳感器采集某一方向磁場(chǎng)強(qiáng)度后通過(guò)控制器對(duì)其進(jìn)行處理并顯示上傳，通過(guò)對(duì)電子指南針硬件電路和軟件程序的分析，闡述了電子指南針基本的工作原理及實(shí)現(xiàn)?！ ?/p> 關(guān)鍵詞：電子指南針；磁阻傳感器；惠斯通電橋；LCD
ABSTRACT:Early compass adopted magnetized pointer and azimuth dish combination, the compass from portability and instructions have certain insufficient sensitivity. The system USES the special magnetic field sensors combined with high speed micro controller (MCU) electronic compass could solve these problems. System uses a magnetic resistance sensors to collect a certain direction after the magnetic field strength of its processing by controller and display the upload, through to the electronic compass hardware circuit and software program analysis, elaborated the electronic compass basic working principle and realization.
