16×16点阵显示屏成功点亮！！看到江同学的3216屏（），对于我来说，稍显复杂，所以决定做个1616的屏看看效果，原理图就是以下了，注意做1616时，要去掉一个74LS154(当然这里也能换用74HC154，虽然功耗大，但价格较低)，经过两天的奋斗，终于完工了。

简单的调试后，点亮了！！编个流动显示的程序，哈哈，很炫啊。

心动不如赶快行动啊！！我是把点阵块焊到一块板子上，可方便检查有无虚焊，控制部分放到了另一张板上，做成的实物图就是下面的了，视频在这里：（注：以下原理图均来自）/*********************************************************程序名称：LED1616点阵流动显示汉字简要说明：最大可显示16*16汉字P0口接上行线，P2口接下行线，P3口接扫描线编写：改编：springvirus*********************************************************/#include <AT89X52.h>#define hang1 P0 //上行线#define hang2 P2 //下行线#define lie P1 //列线#define sum sizeof(hanzi)/32 //自动计算汉字字数/*****参数设置*****/#define ziti 16 //字体大小（宽度）#define light 50 //显示亮度#define move_speed 50 //移动速度unsigned char code hanzi[]={/*-- 文字: 自--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x00,0x00,0xF8,0x48,0x48,0x4C,0x4B,0x4A,0x48,0x48,0x48,0xF8,0x00,0x00,0x00 ,0x00,0x00,0x00,0xFF,0x44,0x44,0x44,0x44,0x44,0x44,0x44,0x44,0xFF,0x00,0x00,0x00,/*-- 文字: 制--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x50,0x4F,0x4A,0x48,0xFF,0x48,0x48,0x48,0x00,0xFC,0x00,0x00,0xFF,0x00,0x00, 0x00,0x00,0x3F,0x01,0x01,0xFF,0x21,0x61,0x3F,0x00,0x0F,0x40,0x80,0x7F,0x00,0x00,/*-- 文字: 小--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x00,0x00,0xC0,0x70,0x20,0x00,0xFF,0x00,0x10,0x20,0xC0,0x80,0x00,0x00,0x00, 0x04,0x02,0x01,0x00,0x00,0x40,0x80,0x7F,0x00,0x00,0x00,0x00,0x01,0x07,0x02,0x00,/*-- 文字: 型--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x10,0x12,0x92,0x7E,0x12,0x12,0xFE,0x12,0x12,0x10,0xFC,0x00,0x00,0xFF,0x00,0x00 ,0x40,0x42,0x49,0x48,0x48,0x48,0x49,0x7E,0x48,0x48,0x48,0x4A,0x4C,0x4B,0x40,0x00 ,/*-- 文字: 点--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x00,0x00,0xE0,0x20,0x20,0x20,0x3F,0x24,0x24,0x24,0xF4,0x24,0x00,0x00,0x00, 0x00,0x40,0x30,0x07,0x12,0x62,0x02,0x0A,0x12,0x62,0x02,0x0F,0x10,0x60,0x00,0x00,/*-- 文字: 阵--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0xFE,0x02,0x12,0x2A,0xC6,0x88,0xC8,0xB8,0x8F,0xE8,0x88,0x88,0x88,0x88,0x00,0x0 0,0xFF,0x00,0x02,0x04,0x03,0x04,0x04,0x04,0x04,0xFF,0x04,0x04,0x04,0x04,0x04,0x00, /*-- 文字: 显--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x00,0x00,0x3E,0x2A,0xEA,0x2A,0x2A,0x2A,0xEA,0x2A,0x3E,0x00,0x00,0x00,0x0 0,0x20,0x21,0x22,0x2C,0x20,0x3F,0x20,0x20,0x20,0x3F,0x28,0x24,0x23,0x20,0x20,0x00,/*-- 文字: 示--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x20,0x20,0x22,0x22,0x22,0x22,0xE2,0x22,0x22,0x22,0x22,0x22,0x20,0x20,0x00, 0x10,0x08,0x04,0x03,0x00,0x40,0x80,0x7F,0x00,0x00,0x01,0x02,0x0C,0x18,0x00,0x00,/*-- 文字: 系--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x00,0x00,0x02,0x22,0xB2,0xAA,0x66,0x62,0x22,0x11,0x4D,0x81,0x01,0x01,0x00,0x00 ,0x00,0x40,0x21,0x13,0x09,0x05,0x41,0x81,0x7F,0x01,0x05,0x09,0x13,0x62,0x00,0x00,/*-- 文字: 统--*//*-- 宋体12; 此字体下对应的点阵为：宽x高=16x16 --*/0x20,0x30,0x2C,0xA3,0x60,0x10,0x84,0xC4,0xA4,0x9D,0x86,0x84,0xA4,0xC4,0x84,0x0 0,0x20,0x22,0x23,0x12,0x12,0x92,0x40,0x30,0x0F,0x00,0x00,0x3F,0x40,0x41,0x70,0x00,/*****空白,用于区分显示内容的头和尾*****/0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00};uint k=0,j; //移位变量,k:移位个数uint a=0; //用于软件延时ulong s=(sum+1)*ziti; //s为全部列数uchar disbuf[16][2]; //定义显示缓冲区（16行两列的二维数组以开辟1个16*16汉字的空间）bit move_st; //移动标志/*****可变延时*****/void delay(void){uchar i;for(i=0;i<light;i++);}/*****初始化子程序*****/void init(void){TMOD=0x1;TH0=0xfc;TL0=0x18;}/*****计数器中断程序*****/void timer0(void) interrupt 1 //中断处理{TH0=0xfc;TL0=0x18;a++;}/*****汉字循环显示*****/void run_move(void){uchar k1,k2;if(a>=move_speed) //move_speed控制移动速度{if(k>s-ziti-1)k=0; //整屏移动列数k1=k/ziti;k2=k%ziti;j=ziti*2*k1+k2; //显示指针k++;move_st=1;a=0;}}/*****装载显示数据至缓冲区*****/void load_hanzi(void){uchar i;run_move();if(move_st){for(i=0;i<15;i++){disbuf[i][0]=disbuf[i+1][0];//移位处理disbuf[i][1]=disbuf[i+1][1];//移位处理}disbuf[15][0]=hanzi[j];disbuf[15][1]=(hanzi[ziti+j]);move_st=0;}}/*****扫描显示数据缓冲区的内容*****/ void display(void){uchar i;for (i=0;i<16;i++){lie=i;hang1=disbuf[i][0];hang2=disbuf[i][1];delay();hang1=0;hang2=0;}}/*****主程序*****/void main (void){ init();EA=1; //开中断TR0=1;ET0=1;while(1){ load_hanzi();display(); }}。
