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。

Description: 用89C51轻松做一个LED汉字显示屏
像搭积木一样，做一屏LED汉字显示
每块显示板有两个16*16的LED点阵，可以显示两个汉字，两块板可以显示4个汉字，
将这两块显示板和一块89S51的CPU板用电缆连接起来，组成一条4个汉字的显示屏，
同样也可以将4块显示板组成8个字的显示屏，显示屏可以滚动，换屏显示，也可以存储若干条短语，用遥控器调用显示短语。-89C51 easily done with a LED display architecture in a building block of Chinese characters, as do a Chinese character display screen LED display board at each of two 16* 16 LED dot-matrix, you can show two Chinese characters, two pieces of board can display four Chinese characters, these two display boards and a piece of the CPU board 89S51 cable linking the composition of a display of four characters, the same can also be composed of four display panels 8 character display, the screen can scroll, change screen display, you can store several phrases, use the remote control to call display phrase.
