毕业论文流水灯的选题意义

STC89C52的片子，想用P1口的四个引脚控制四个反光二极管，

第一个灯亮过之后，延时一段时间，第二个亮，以此类推，

当第四个亮过之后就让四个二极管全亮（或全灭），然后保持。

感觉是一个非常简单的程序，但是就是不能实现。

要求不高，实现起来，确实是非常简单。

众网友提供了 C 程序，明显是小题大做了，难怪楼主不采纳。

汇编语言的程序如下：

本程序已经通过检验。

在这里，引用网友的效果图，如下：

我也是做流水灯的毕业论文,英文部分太难找了,给个建议吧

Since the introduction of computer-chip technology in society, in every field in a wide range of light control systems, the microcontroller is replaced by the gear regulating the delay time of old growth rate in future in the heart of this to the MCU has several benefits: small size, light weight, a single power supply; features, low power consumption and low; and the data transfer, one finds in SCM internal, run fast, uding, high reliability, so single-chip is widely used in measurement and control system, data acquisition, instrumental, Mechatronics product, smart interface, computer communications, as well as single-chip multilevel system, article is primarily deals with a subject name is single-chip-chip, flowing water and light control, which enables we learned how to use the SCM control our lives in the application of the design of this subject at a later time, introduced me to many aspects of the topic describes in detail by the MCS-89C51 manifold programming the control circuit, it completed the single-chip flowing water and light control features, and gives specific hardware circuits and the appropriate kind of control circuit reliability, flexibility, use the wide-ranging especially suitable for medium-sized cities of traffic lights, neon lights, , it on other similar system has certain significance.

#include <>

#include<>

#define uchar unsigned char

uchar j,temp;

void delay(unsigned int ms)

{

uchar t;

while(ms--)

for(t=0;t<123;t++);

}

void main()

{

P1=0xff;

delay(500);

temp=0xfe; //有点怪，led接在

for(j=0;j<4;j++)

{

P1=temp;

delay(500);

temp=_crol_(temp,1);

}

P1=0xff;

while(1);

}

我是一名多年的单片机工程师，下面的程序你参考一下

效果图

程序如下：

#include<>

#include<>

#define uchar unsigned char

#define uint unsigned int

uint i;

uchar j;

void delay_ms(uint k)  //延时子程序

{

for(i=0;i

{

for(j=0;j<230;j++)

{

;

}

}

}

main()

{

uchar a,b;

P1=0xfe;

delay_ms(500);

b=P1;

while(1)

{

for(a=0;a<3;a++)

{

b=_crol_(b,1);

P1=b;

delay_ms(500);

}

P1=0xf0;

delay_ms(500);

P1=0xfe;

delay_ms(500);

b=P1;

}

}

PS 你们老师不会真的看内容的 直接翻译一下说的过去就行了囧 流水灯也能做毕业论文……
