Description: 单片机并行I/O口数量总是有限的，有时并行口需作其他更重要的用途，一般也不会用数量众多的并行I/O口专门用来驱动显示电路，能否用80C51的串行通信口加上少量I/O及扩展芯片用于显示电路呢？答案是肯定的。
80C51的串行通信口是一个功能强大的通信口，而且是相当好用的通信口，用于显示驱动电路再合适不过了，下面我们就根据这种需要设计一个用两个串行通信口线加上两根普通I/O口，设计一个4位LED显示电路。当然只要再加上两根I/O口线即可轻易实现8位LED的显示电路。-SCM parallel I / O I always limited quantity, and sometimes parallel port need for other more important uses, generally will not be used for a large number of parallel I / O I show devoted to the drive circuit 80 C51 able to use the serial communication port with a small amount of I / O and expansion of chips for the display circuit? The answer is yes. 80C51 Serial Communications mouth is a powerful communications mouth, but is very handy communications mouth, for the display driver circuit could not have been more appropriate, Now we need to design the basis of this one with two serial communication lines with two general I / O Hau, Design of a four LED display circuit. Of course if coupled with two I / O lines I could easily achieved eight LED display circuit.

Description: 简易数控直流电源
摘要：本实验设计了一个以单片机89C51为基本控制核心的简易数控直流电源。.该设计包括直流电源输入及输出两部分，可完成0~15V之间各不同幅值的电压的输出，能够预置数，能够自动扫描输出电压并直接显示到LED数码显示管上，并可扩展输出三角波等波型。其中电压输出部分，既可手动的每按”+””-”键一下进行每0.1V大小的上下调整，也可长按”+””-”键使其自动的递增或者递减，直到需要的数值。预置数时用切换键切换预置个位或小数位，按”+””-”键进行微调。单片机编程部分是基于WAVE6000软件上设计，并在实物上进行仿真。.该系统具有抗干扰性能好，可靠性高，及最终输出电压值与真实显示值精确度较高等优点。
