摘要
为了克服在单片机教学实验中实验箱体积大,成本高,维修率高,学生难学的缺点,本文论述了利用LED和单片机,用循序渐进的方法,开发了基于LED数码管的单片机显示电路实验平台,实验平台由5个功能模块组成:单片机I／O口与单个7段LED数码管构成显示电路;多个LED动态扫描显示电路;串行口动态扫描LED显示电路;时钟LED显示电路。现在实验平台在本校单片机教学中得到广泛应用,效果良好。
In order to overcome the shortcomings of big volume of testing box, high costs and service rate, as well as difficult learning for the students in SCM teaching experiment, This at＇tide elaborates the LED and SCM to be used with the method of following in order and aduanced step by step, the SCM display circuit testing platform based on LED mumerals code tabe is developed, the testing platform is composed by 5 function models; i.e., SCM I/O interface and display circuit constituted by individual 7 sections of LED numerals tubes; Multi LED dynamic scanning display circuit; The serial interface dynamic scanning LED display circuit; As well as the clock LED display circuit. Now, the testing platform obfains a widespread application for the SCM teaching in the school, the reaults are excelleut
