这是自己做的编写的压力测量系统，用Proteus模拟器件并编写程序。压力传感器用电流源并联电阻模拟，ADC0808采集电压信号，8279控制显示和读取键盘，程序功能有三，1、采集压力信号并显示；2、校准程序；3、测量程序并显示。ad转换程序调试完成，8279并未完好。仅供大家参考-This is a pressure measurement system to write your own program, the pressure sensor with a current source and resistor simulation, ADC0808 acquisition voltage signals 8279 control the display and read the keyboard, the program features three, one, the pressure signal acquisition and display　2, calibration procedures　3 , measurement procedures and displayed. ad conversion program debugging completed, 8279 was not good. Only for your reference
