基于89s51的keil跑马灯工程，程序虽然简单，但是它的经典程度不亚于软件开发中的“hello word”，单片机汇编编程者不妨参考一下。内附proteus完整的仿真文件。-Based on the keil Marquee 89s51 works, the program is simple, but it is no less than classic software development in the " hello word" , the compilation of single-chip programmers may wish to reference. Proteus simulation containing the complete document.
