说明：  资源中包含proteus仿真图、C语言程序代码以及编译好的hex文件，测试可用。 采用中断方式，对2路0～5V的模拟电压进行循环采集，采集的数据送LED显示，并存入内存。超过界限时指示灯闪烁。 本质上是以单片机为控制器，ADC0809为ADC器件的AD转换电路，设计要求的电压显示，是对ADC采集所得信号的进一步处理。
(Resources include proteus simulation diagram, C language program code and compiled hex file, test available. Interrupt mode, the 2 ~ 0 ~ 5V analog voltage cycle collection, collected data sent to LED display, and stored in memory. Over limit indicator light flashing. Is essentially a microcontroller for the controller, ADC0809 for the ADC device AD conversion circuit, the design requirements of the voltage display, ADC acquisition of the signal is further processed.)
