基于ARM控制的心电显示系统的设计

Design of ECG Displaying System Based on ARM

介绍了一种采用LPC2368主控芯片和点阵式LCD显示器设计的LCD心电显示系统,它能准确清晰地显示心电波形。同时在嵌入式系统中进行了数字滤波算法的程序设计,包括一种基于ARM微处理器的块FIR数字滤波器的实现方法、中位值滤波算法和算术平均滤波法。

This paper describes a portable ECG display system, developed by using the main chip LPC2368 and the liquid crystal graphic display （LCD）. It can provide accurate, high resolution display of ECG waveform. And we use the programming of digital filtering algorithm in embedded systems, including a block algorithm about FIR filtering based on ARM, the filter algorithm of the median value, and the filtering algorithm of arithmetic mean.
