十字旋转屏报告

旋转LED显示屏设计与测试 姓    名：  姜  x      学    号：  20112410212    班    级：  （二）          专    业：  电子信息工程  一、实验任务 基于视觉暂留原理，设计一种旋转式LED显示屏，使其能够显示预设的文字，图案等。 二、显示原理 人眼在观察景物时，光信号传入大脑神经，需经过一段短暂的时间，光的作用结束后，视觉形象并不立即消失，这种残留的视觉称“后像”，视觉的这一现象则被称为“视觉暂留”。肉眼在24帧/秒以上就不会看到闪烁的，所以只要保证电机的速度能在一秒转24圈以上，这样的话人眼就觉得旋转的字很稳定很清晰的显示在空中了。 如果我们用电机带动led主板转动，以stc89c52单片机为控制中心，16个io口分别控制16个led，再加上一个红外发射管，一个红外接收管。led主板上的红外接收管每转动一圈红外接收管就会导通一次。一旦导通，单片机检测到引脚的低电平，便让单片机开始有规律的控制16个led的亮灭，这样，由于人眼的“视觉暂留”效应 ，便能看到显示屏上显示的文字或图像了。 要想准确显示一个字体或者图形，我们就要准确的给16个管脚赋上有规律的高低电平，要想知道怎样赋值，我们需要对文字或者图形取模，因为我们用的是16个led灯，所以我们取一个16*16的中文字，如图1示 图1  对汉字取模 从第一列开始向下每取8个点作为一个字节，如果最后不足8个点就补满8位。取模顺序是从低到高，即第一个点作为最低位。取模后数据如下：0xFF,0x7F,0xFF,0xBF,0x3F,0xC8,0xBF,0xFB,0xBF,0xFB,0xBF,0xEB,0x80,0x9B,0xB7,0xFB,0xB7,0xEB,0xB7,0x9B,0xB7,0xFB,0x37,0xF8,0xF7,0xEF,0xF7,0x1F,0xFF,0xFF,0xFF,0xFF,/*"点",0*/ 现在我们知道16*16取模是一列一列取的了，一列有2个字节，一共16列，所以一个16*16的汉字就有32个字节，需要占用单片机的Code空间 32个字节。 Led每旋转一周红外接收管接收信号时，单片机便开始根据取模后的数组开始依次点亮16个led。这样，便能显示文字或者图形了。 3、硬件设计 控制芯片采用STC89C52，结构框图设计如图2所示 图2 系统结构框图 本系统采用无线供技术。利用自激震荡电路，把5v直流电压转换成交流电压。然后通过线圈电磁感应，给led主板供电。电源电路原理图如图3所示 图3  电源电路原理图 本系统用p2口，p4口，p5口控制16个led灯，次级感应线圈产生感应电压系统电路原理图如图4所示 图4  系统电路原理图  制作完成后，下载硬件测试程序进行测试，如果16个led灯能够全部点亮，则制作成功，可以作为显示屏使用，硬件测试程序见：六、程序 四、程序分析 本次实验采用查询方式编写程序，程序结构流程图如图5所示 图5  程序流程图 当程序开始运行的时候，首先就是要对程序进行初始化，主要作用就是让程序按照我们所设计的初始值去运行。初始化之后，当显示屏旋转到接收到红外发射信号时，开始执行显示程序，有规律地点亮16个led灯。16个led及其对应引脚如图6所示 图6  16个led及其对应引脚 一列灯16个 刚好对应16*16一个汉字的一列：2个字节，所以把取模到的数据依次送到P2口 和P4 P5口，这里硬件中P4 P5组成一个字节，所以显示程序如下： for(i=0;i<16;i++) //送16列  显示 这里只显示一个字。 {                    P2=zimo[i*2]; //送数据低位显示 P4=(zimo[i*2+1]);//送数据高位显示    这里用了单片机P4 和P5口 是LQFP48脚才有的IO口  P5=(zimo[i*2+1])>>4;//这里行和列 都是IO口独立驱动的LED DelayUs(200);    //延时让LED亮起来 每列延时的时间 P2=0XFF; P4=P5=0XFF; } 在什么时候送显示呢？单片机IO一判断到 红外接收管接收到起点信号，就开始显示，显示完16列后等待下一次的起点信号。这样只要电机的速度够快就会稳定的把字显示字空中了。平面的文字显示同理。 如何让一组文字不断的移动？这就需要一个字幕计数器，旋转LED每旋转一圈，这个字幕计数器就加一，指向下一列，这样不断的刷新，感觉文字就在移动了，程序如下： j就是字幕计数器，每转一圈j就会加1； if(KEY==0) //红外接收管 判断起始位 { j++;            if(j>672) //根据显示的字数定义改数值672/16=42个字 显示完42个字后 重新开始 { j=0 ; }            for(i=j;i<128+j;i++) //每转一圈  前进一列  这里定义一圈中同时显示128/16=8个字， {                                                                                      P2=zimo[i*2]; //送数据低位显示 P4=(zimo[i*2+1]);//送数据高位显示    这里用了单片机P4 和P5口 是LQFP48脚才有的  P5=(zimo[i*2+1])>>4;//这里行和列 都是IO口独立驱动的LED DelayUs(200);    //延时让LED亮起来 每列延时的时间 P2=0XFF; P4=P5=0XFF; } 这样，利用查询法，执行显示程序，便能在显示屏上显示预设的文字或者图形了。 5、实验结果： 我们把程序下载进单片机，接通电源，旋转屏便能显示我们预设好的图形和文字了。本次实验先显示几个图形，然后滚动显示“郑州大学信息工程学院”几个字。显示效果如图7所示 图7  实验显示效果 六、程序 硬件测试程序： #include #define uchar unsigned char #define uint unsigned int unsigned char temp=0X0;
