摘要
本文对一套基于ARM的嵌入式数据采集系统的设计与实现作了介绍,该数据采集系统不仅能作用于温湿度等常规信号,而且能对核脉冲等快速变化的信号进行采集和处理。系统以S3CA4B0X01为核心控制单元。加上ADS774的模数(A/D)转换功能,能够保持在较低功耗下实现对外来信号进行快速精确地获取。
This paper introduces the design of the embedded data collection system based on ARM7S3C44B0X01.This high speed and accurate system uses S3C44B0X01 as the core control unit and ADS774A/D block are also added in the system to implement the collection,conversion and storage.
