点阵显示屏成功点亮 原理图 程序.doc
1616点阵显示屏成功点亮！ 看到江同学的3216屏（www.jiangx.net），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：http:/u.youku.com/springvirus （注：以下原理图均来自www.jiangx.net）/*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： JiangX.net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,0xE8,0x88,0x88,0x88,0x88,0x00,0x00,0xFF,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,0x00,0x00,0x00,0x00,0x20,0x21,0x22,0x2C,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,0x86,0x84,0xA4,0xC4,0x84,0x00,0x20,0x22,0x23,0x12,0x12,0x92,0x40,0x30,0x0F,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 disbuf162; /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+) disbufi0=disbufi+10;/移位处理 disbufi1=disbufi+11;/移位处理 disbuf150=hanzij; disbuf151=(hanziziti+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=disbufi0; hang2=disbufi1; 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();
