2410芯片自带的AD实验，采集一个模拟电压值显示到串口上，调节变阻器可以改变这个模拟电压值-2410 chip own AD experiment, collecting an analog voltage value to the serial port on the display, adjust the rheostat can change the analog voltage value

在89c51 型 系统上 运用tlc2543芯片 模拟数字电压 实现功能(In 89C51 type system, the TLC2543 chip is used to simulate the digital voltage to realize the function)

k题完整程序是用了51单片机为主控芯片，用ad转换数据并在显示屏上显示出来(K Title complete program, using 51 single-chip microcomputer as the main control chip, with AD conversion data, and displayed on the screen)
