自己课程设计做的单片机89C52的c语言程序，主要功能为数字时钟，可设置时间，星期数。用Keil把c代码加入new project中就可以调试了。包里还有个Proteus的电路图，没上传原文件，我觉得电路图还是自己动手画画比较好吧。-My own curriculum SCM 89C52 c language program, the main function for the digital clock, can set the time, days of the week. Keil c code to use the new project in the can debug. There are a Proteus schematic bag, did not upload the original file, I think the schematic drawing is good for you.
