在编程软件配合下，要求实现如下功能：调解电位器RV1可使其输出电压在0~5V之间变化。经A/D转换后，数码管以十进制数形式动态显示电位器的调解电压。(In cooperation with the programming software, it is required to realize the following functions: The adjustment potentiometer RV1 can change its output voltage between 0~5V. After the A/D conversion, the digital tube dynamically displays the potentiometer's mediation voltage as a decimal number.)
