51单片机 8*8点阵26个英文字母怎么样显示 用51单片机以及8*8点阵显示英文字母或者数字（最好是全部数...

你真厉害，一位数组显示点阵实验，点阵最好是用二位数组，基本思路也就是单片机两个IO口控制点阵的行和列，定义一个二位数组控制点阵每一行要亮拿几个灯，然后下一行亮那几个灯，以此类推，快速刷出没一个亮的灯就能让人感觉是一个字了，好啦，给你程序你自己看吧

我建议你套用这个程序之后把延时的时间改长一点，最好到个500ms左右，这样你就可以清楚的看到点阵是怎么显示字的了

要么是转换程ASCII码显示，要么直接加引号送液晶显示，看你用了数组，可能是转成ASCII显示。

在百度搜索里敲入“字符点阵 软件”
一大堆！！自己看看吧

8*8点阵是动态扫描的 静态显示也是动态扫描的结果。
比如说下面这个程序：
#include
#include "74HC595.H"
unsigned char code a[]={0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};
unsigned char code b[]={0x00,0x7F,0x40,0x40,0x40,0x00,0x00,0x00};/*"L",0*/
void main(void)
{
unsigned char i;
while (1) //如果没有while循环，将出现闪烁现象
{
for(i=0;i<8;i++)
{
Ser_IN(a[i]);//8X8点阵列扫描
Ser_IN(b[i]);//8X8点阵行扫描
Par_OUT();//74HC595输出显示
}
i=0;
}
}
程序里面还要包含"74HC595.H"
把它放在工程文件夹里面就可以了。"74HC595.H"具体程序如下：
#ifndef __74HC595_H__
#define __74HC595_H__

sbit SD = P1^4; //串行数据输入
sbit ST_CK = P1^5; //存储寄存器时钟输入
sbit SH_CK = P1^6; //移位寄存器时钟输入
void Ser_IN(unsigned char Data); //串行数据输入
void Par_OUT(void); //串行数据输出
//void Ser_Par(unsigned char Data); //串行输入,并行输出
//串行数据输入
void Ser_IN(unsigned char Data)
{
unsigned char i;
for(i = 0; i < 8; i++)
{
SH_CK = 0; //CLOCK_MAX=100MHz
SD = Data & 0x80;
Data <<= 1;
SH_CK = 1;
}
}
//并行数据输出
void Par_OUT(void)
{
ST_CK = 0;
ST_CK = 1;
}
//串行输入,并行输出
void Ser_Par(unsigned char Data)
{
Ser_IN(Data);
Par_OUT();
}
当然，由于不同的单片机引脚不同，可能编译没错，但是实际是显示不了的。
就是那么多，望采纳。
