本文介绍了用两个 UGN3503型霍尔器件设计制作的数字指南针的设计目的、系统结构和工作原理,以及各主要器件的使用方法。本系统包括UGN3503型霍尔器件、TLCO832A/D转换器、单片机控制、液晶显示四部分,实现了对地磁信息的采集、放大,经过模数转换和单片机处理,最终显示出用文字表示的当前所处方位。
This article describes the design purpose, system structure and working principle of the digital compass designed and manufactured by two UGN3503 Hall devices, and how to use each main device. The system includes Hall device UGN3503, TLCO832A / D converter, SCM control, liquid crystal display four parts, to achieve the collection of geomagnetic information, amplification, after analog-digital conversion and single-chip processing, and ultimately showed the current text Aptitude
