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: 这是我看了《十天学会单片机》（郭天祥的教程）/*这个程序，是我用51电子网，298元C51学习板调试通的单片机控制DS1303时钟芯片试验时请用排线
将p1口连到CZ2
一个时钟程序，它能实现断电走时（用纽扣电池），显示和设置年月日星期时分秒（8位数码管）。
*/（http://www.51dz.com/n.asp?id=12519&i=xie343706382）测试时请将p1口用排线连到CZ2上，控制8位
数码管用。P0口用来检测矩阵键盘的，P3.0和P3.1是串口通信用，控制74H164N芯片段选8位数码管。
我的QQ343706382，希望有喜欢单片机的朋友。和我联系。-This is what I read "10 days Singlechip Society" (郭天祥tutorial)/* this procedure is that I used 51 electronic networks, 298 yuan C51 learning board s single-chip debug control DS1303 clock chip testing, please use row p1 mouth line will link to a clock cz2 procedures, it can achieve power away (with button batteries), display and set the date when the minutes and seconds a week (8-bit digital tube).*/(Http://www.51dz.com/n.asp?id=12519 Platform: |
