摘要
文章通过介绍S3C44B0X内部的8路模拟信号输入的10位模/数转换器(ADC)的功能和工作原理,进而研究如何利用嵌入式系统研制A/D数模转换器,实现数字信号与模拟信号的转换接口电路。根据逐次逼近型ADC的工作原理来分析ADC转换数值子程序。
Articles by introducing S3C44B0X internal 8-channel analog signal input 10-bit analog /digital converter(ADC) of the functions and working principle led him to study how to use the embedded system development A /D converters,digital signal and analog signals conversion interface circuit and to analyze the ADC conversion value subroutine according to the working principle of approximation ADC.
