【无聊大作战】光立方制作
这一阵刚休息闲着无聊制作8X8X8光立方,应为是初学者有什么问题请见谅啊!~~~
一、光立方的基本原理
利用人眼的暂留效应,利用单片机控制LED灯泡快速的闪烁,显示出一个完整的图案!
二、使用工具和材料
(一)、使用工具:1、焊枪(不用这么好的,随便哪种便宜的也行)2、剥线钳3、锯子(要是相信自己的手工能力,就挑战手锯吧,手锯便宜啊!)4、钢尺5、电钻6、电流表(主要用来测是否焊错的)7、镊子8、热熔胶枪(可有可无)
(二)使用材料:1、单片机X1个2、最小系统X1个(带写入功能的,我这个是不带的,应为我有实验板)3、74hc136X9个4、74hc573X1个5、LED灯X516个(颜色无所谓)6、排插、排针多个(排插至少要两排,做底盘需要64个点)7、实验板(看大小购买,够用就行)8、热缩管(不用太多,够用就好)9、电线(这个要不少,看着来吧)10、20针插座1个、16针插座9个
(三)原件原理
1、74hc138:作用是用三位二进制数,来输出只有一位为零的八位二进制数
2、74hc573:锁存器,在这次中没用的什么功能,主要用来电流放大的,
OE、GNG直接地线,Vcc、LE直接接电源就行了。
三、-->电路图
应为是一个8X8X8的立体结构,用三轴坐标系就可以分别控制单一一盏灯
74hc573(Y)控制Y轴
74hc138(Z)控制Z轴
74hc138(X1~X8)控制X轴
四、制作流程
现在开始正式制作了,前面全是准备。
1、 弯LED灯的针脚,注意正负极不要搞错了,一共弯512个,多弯上几个,作为备用的。
2、 制作定位板,井字形的间隔为20mm,8行8列共计64个点,可以用纸张划线代替。(我这个其实只有7*8个实在是没大板子了!~~)
3、 用定位板焊接单一一排8个,正极正极项链焊接,中间间隔20mm,一共焊64条。
4、 64个单条焊好后,用8个单条组成一个面,这时是负极与负极相连,每条之间的间距是20mm,焊接时顺便调整阵脚,不要短路了。一共8面。
5、 焊好8面以后,就是测试环节了,负极串联起来,给每一行的正极单独供一次电观察有没有短路、没亮、亮度暗等问题的,及时更换,修理。
6、 制作插座,将排插剪开只留下中间的铜质圆柱插座,直接焊接在实验板上,横竖各8排,其中间隔20mm,共计64个点。焊好后背面每个点连出一条线,用以连接74hc138(X1~X8)。线路简单的梳理一下用东西暂时固定一下。然后在线的另一端用剪开的排针焊上一个插头,以备后面连接使用,焊好后套上热缩管(这些图片都不是当时照的,这是已经锯掉一半了,另一半和这一半一样)
7、 将8个面插到低上,将横向相邻的正极弯好后直接焊道一起,注意之间的间隔是20mm,使每一层所有灯的正极是串联在一起的,然后每一层单独引出一条线(图中的红线),分别插在74Hc573(Y)的O0~O7口上。
8、 焊好后就可以放到一边了,接下来就是焊控制电路了。
我们不用将芯片直接焊在实验板上,先焊插座,让后将芯片插进去,这样就不会出现烧坏芯片的情况了。
74hc138(X1~X8)焊接在一块将这8块芯片的Vcc、E3全部串联到一起用来输入电压,GND,E2串联到一起直接接地,然后是A、B、C、分别串联一块,分别连接单片机的P1.0口、P1.1口、P1.2口,Y0~Y7分别单独的向正面引出排插每一个口单独焊接不是串联,用来连接底座上的64个点,E1向正面单独引出一个排针,用来连接74Hc138(Z)的(Y0~Y7)。焊接完成后用万用电流表检查是否有虚焊,焊错的。
74hc138(Z)和74HC573(Y)的焊接方法都是每个针单独连接一个排针。
9、74hc138(X1~X8)焊接在一块将这8块芯片的Vcc、E3全部串联到一起用来输入电压,GND,E2串联到一起直接接地,然后是A、B、C、分别串联一块,分别连接单片机的P1.0口、P1.1口、P1.2口,Y0~Y7分别单独的向正面引出排插每一个口单独焊接不是串联,用来连接底座上的64个点,E1向正面单独引出一个排针,用来连接74Hc138(Z)的(Y0~Y7)
74hc138(Z)A、B、C口分别连接单片机的P1.3口、P1.4口、P1.2口
74hc73(Y)D0~D7八个口连接单片机的P0的八个口,OE、GNG直接地线,Vcc、LE直接接电源就行了。剩下的O0~O7口分别连接Y轴的每一层。
直接算是彻底的安装好了。
装饰用的自选项:
1、 剪裁出180mmX180mm正方形,在背面画井字形方格,间距20mm,然后再交错点处打孔。
2、 将底板锯开,接头一一对应的插入钻好的孔,用胶水固定,全部粘好后,梳理线路用热熔胶将线路粘牢,再将每一列的八条线用热缩管捆到一起。
这就算是彻底的完成了!~~~

单片机是随着微型计算机、单板机的发展及其在智能测控系统中的应用而发展起来的。以8位单片机为例,其发展过程大致可归纳为四个阶段。

程序用来显示的图案应为暂时没有时间去编了,只能靠大家来整了!~~
图案的编辑规则是:应为是每一次给Y轴一个8位的图案,所以只要64次就可以循环过来了,如图示,第一面显示完成后第二面开始显示,来回八次,直到第八面显示完成,再次转到第一面,再次循环以上步奏,因为速度哦够快,就可形成完整的图案安了。
所以如果要形成一个完整的图案就要有64个数据。
这就算是彻底的制作完成了!~~

摘要:一种液晶显示可变情报板,由编缉显示通讯PC机发送显示数据给通讯控制器,通讯控制器中的单片机8051在收到传送来的显示数据后,再以点阵位格式将显示数据地址传送给移位寄存器,将显示数据传送给数据锁存器,LCD显示板上的显示控制器在收到显示数据和选通地址后,再将指定位的LCD显示点打开,显示规定的内容。大点液晶LCD显示矩阵,之间缝隙在显示图文中忽略不记,采用8051单片机控制液晶显示模块以高速串行静态方式显示点阵图文,10平方米的显示屏只需1秒左右即能完成画面变换显示。解决了现在LCD发光二极管大屏汉字显示屏的功耗大和白天在户外受阳光影响显示不清楚的问题。
