Description: 单片机控制ADC0809的模数转换与显示，硬件电路是由AT89C51最小系统、ADC0809模数转换模块、显示模块这几个模块来构成。利用两个程序分别实现ADC0809的查询工作方式和中断工作方式。主程序流程是利用软件的方法实现ADC0809时钟信号的，因此程序中设计了定时器1中断，每一次中断服务程序，都会改变接在ADC0809时钟引脚上的电平，一模拟ADC0809所需的时钟信号。-ADC0809 microcontroller analog-digital conversion and display, the hardware circuit is the smallest system by AT89C51, ADC0809 analog-digital conversion module, the display module to form these modules. Using two procedures to achieve ADC0809 query work and interrupt work. The main program flow is the use of software to achieve the ADC0809 clock signal, so the program design Timer 1 interrupt, interrupt service routine each time, will change the ADC0809 clock pin connected to the level of a simulation ADC0809 required clock signal.
