一个电压转换的程序,实现对模拟量的采集和控制,在系统中反馈

PIC单片机模拟量采集源程序，在PROTEUS软件里仿真过,PIC single-chip analog acquisition source, in the PROTEUS simulation software have been

用热电阻Pt100做温度传感器，采用惠斯登电桥测量电路，将随温度变化的热电阻变化量转换成模拟电压信号；用LM324设计放大电路；以12位串行模数转换器ADS7816将模拟电压信号转换成为数字信号；单片机将采集到的数字信号经过平滑处理、变换成温度量用数码管显示出来。-To do with hot 电阻 Pt100 temperature sensor, the use of Wheatstone bridge measurement circuit, the temperature depende

用STC89C58单片机做的数据采集和控制，11位AD转换使用mc1433，支持模拟量或数字量的读写-STC89C58 to do with single-chip data acquisition and control, the use of 11 AD conversion mc1433, support for analog or digital reading and writing
