摘要
主要介绍以MSP430F149微处理器为核心,采用高精度硅压式压力传感器MIDA-MG-70和高精度积分式A/D转换器AD7714等器件对压力信息进行采集转换,完成了具备A/D转换、数据处理、温度补偿、串口通讯等多种功能的高精度压力数据采集系统。
A high accuracy pressure data acquisition system is introduced in this paper, which adopts MSP430F149 as core, pressure sensor MIDA-MG-70 and A/D converter AD7714 as data acquisition and conversion module The system realizes the functions of A/D conversion, data processing,temperature compensation, serial portcommunication and so on. It gives description about hardware and sottware in detail.
