C语言电子教案-2.4点阵LED显示

C语言电子教案-2.4点阵LED显示

2.点阵的工作原理
以8X8点阵LED的工作原理作说明： 从图中可以看出，8X8点阵共需要64个发光二极管组成，且每 个发光二极管是放置在行线和列线的交叉点上，当对应的某一 行置1电平，某一列置0电平，则相应的二极管就亮。若要使某 一行亮，则对应的行置1，而列则采用扫描依次输出0来实现。 若要使某一列亮，则对应的列置0，而行则采用扫描依次输出1 来实现。
2. LED点阵的显示方法
首先在P0送首个行码00H，在P2口首个列码FEH； 接着在P0送第二个行码00H，在P2口第二个列码FDH； 再在P0送第三个行码3EH，在P2口第三个列码FBH； 依次把所在的行码送完，这样就可以显示一个“0” 字了，接着再重复上述过程，把所有的数字都显示完就 可以达到效果了。
2. LED点阵的显示方法
作业：请每位同学把自己名字的每个字首字母显 示出来。 如“张三”显示为“ZHS”.
2.4点阵LED显显示器件是将要显示的字符（包括汉字）， 主要适用于汉字显示。 点阵显示器的种类 按大小分，可分为5×7，5×8，6×8，8×8等4种； 按LED发光变化颜色分，可分为单色、双色、三色； 按LED 的极性排列方式又可分为(行/列)共阳极与(行/ LED ( / ) ( / 列)共阴极。
2. LED点阵的显示方法 思考：要想在8×8的LED点阵上显示一个数字，是 否能同时将这些LED进行点亮的？ 因为点阵的行公共端或列公共端是连接在一起的， 就像我们在前面讲过的数码管的动态显示类似，是 不能同时将这些LED进行点亮的，只能采用按行或 者是按列进行控制。
2. LED点阵的显示方法 行扫描 指先扫描显示第i行，然后关闭第i行（即第i行所有 LED都不亮），接着显示i+1行、i+2行、 i+3行…… 最后再回到第i行，如此循环。 列扫描 指先扫描显示第j列，然后关闭第j列（即第j列所 有LED都不亮），接着显示j+1列、j+2列、 j+3列 ……最后再回到第j列，如此循环。

32×64点阵式LED显示屏设计

32×64点阵式LED显示屏设计

摘要LED显示屏是利用发光二极管点阵模块或像素单元组成的平面式显示屏幕。

它是多个独立的LED发光二极管封装而成，LED点阵显示屏可以显示汉字、数字、符号等，通常用来显示文字、时间、速度、系统状态等。

由于它具有发光率高、使用寿命长、组态灵活、色彩丰富以及对室内外环境适应能力强等优点，所以广泛应用于广告、证券、信息广播、新闻发布等方面，是目前国际上级为先进的显示媒体。

文章给出了一种基于AT89C52单片机的32 x 64点阵LED显示屏的设计方案。

包括系统具体的硬件设计方案，软件流程图和C语言程序等方面。

LED点阵显示屏是将要显示的汉字字模代码保存在某个存储空间，单片机通过读取字模并做相应的处理，然后以不同的显示方式显示在点阵屏上，主要适用于室内外汉字显示。

在负载范围内，只需通过简单的级联就可以对显示屏进行扩展，是一种成本低廉的图文显示方案。

32乘64点阵

板子上有8*8点阵模块32块， 32块74HC595，一个7805，两个7406，一个74ls138，1个74ls244， 8个IRF540 大功率MOS管。

上面一半是红的，下面一半是绿的。

测试环境：（屏需要3.5v 和 9v电源）屏的接口：这个屏的布局是这样的，用D0~D3，控制4个横条的数据，每条里有8行LED。

一整行的数据是一次传完,64bit. 每条里的每行是通过74ls138解码产生的。

ABC是74LS138的ABC编码输入，E是输出允许，低电平有效。

S是74HC595的锁存，Y是串行时钟，D0~ D3是4排74HC595的数据输入端。
