设计一个带计数使能、异步复位、异步装载、可逆计数的通用计数器。计数结果由七段数码管显示-Designed with a count enable, asynchronous reset, asynchronous loading, reversible counting universal counter. Counting results from the seven-segment LED display

将目标程序下载到单片机内，是六个七段数码管前三个显示电压，后三个显示重量-The goal of the program is downloaded to the microcontroller, the first three of the six seven-segment LED display voltage, after three display weight
