74hc595要用四片 行列扫描 把两组（一组两片）的锁存脉冲接在一起。然后把第一片的Q7‘接入第二片的SDA。另外把每组SCK接在一起。十六位的移动是只 你往595里送个数据。那么595就会把最先送入的数据丢掉。然后整体

20H-27H单元是存好的要显示的汉字，程序整体你应该明白，就光说说显示子程序部分哈 START: LCALL DISPLAY SJMP START DISPLAY: MOV R7,#8 ；R7预存 数“8”MOV R2,#11111110B ；R2用来列选 MOV R0,#20H

1、8*8双色点阵实际上是两个8*8点阵，必须增加一个端口来控制是使用哪个颜色的8*8点阵；或者连接成一个8*16点阵来控制。C语言代码和控制8*8点阵类似，增加扫描端口就可以了。2、例程：include unsigned

void WriteByte(uchar dat) { uchar k;for(k=0;k<8;k++){dat=dat>>1;DS=CY;SH_CP=0;SH_CP=1;}}void main(){uint num,temp,n,m;while(1){ for(n=0;n<112;n++)for(m=0;m<8;m++) //重复显示

P1=0xff;WL=0;while(1){ for(a=0;a<8;a++){ P0=table1[a];P1=table2[a];delay(2);} } }

这个程序验证过，你可以参考试试：//---//8*8矩阵循环显示字符和数字//显示字符串在数组disstr[]中申明//---#include#include#define uchar unsigned char#define uint unsigned int//---uchar

回答：// 5*7(2)点阵 pzowen #include #include #include #include #include #include #include #include #

void main(){ unsigned char w,i;while(1){ //显示0 w=0x01; //行变量为第一行 for(i=0;i<8;i++){ P1=w;//行数据送P1口 P0=led0[i];delayms(1);//列数据送P0口 w<<=1;//向下移动一行 }

求一个8*8LED点阵汉字显示C语言程序(C52)

1、可以通过左移函数_crol_()和右移函数_cror_()来实现LED等的来回流动。2、具体实现方法可以参考如下程序：

if(led1==0xff)led1=0x7f;delay(100);case 2:P0=led3;led3=(led3<<1)|0x01;if((led3&0xf0)==0x30)led3=0x3e;if((led3&0xf0)==0x70)led3=0x7c;if((led3&0xf0)==0xf0)led3=0xf8;break;case

按行取模可以向上移动，按列取模才可以向左移动。以按列取模为例，每个字的字模表中第1，2字节送LED屏第一列显示，依次显其余15列。假如显示0.5秒(时间可以调)，再取字模的第3，4字节，还送LED屏第一列显示，依此

MOV DPTR,#HZKE ;此处设定所要显示的字符 MOVC A,@A+DPTR CPL ACC ;代码取反,决定显示的阴阳 MOV DPTR,#CSr1 MOVX @DPTR,A MOV A,R5 RL ACC INC ACC MOV DPTR,#HZKE ;此处设定所要显示的字符 MOVC

怎样用C语言实现led点阵显示字符移动

第一步，先将Proteus运行起来，同样新建一个Arduino 328的项目，自己为项目取个名字，此处取名为LEDMatrix。第二步，要从元件库当中找到LED点阵，并添加到工作区。点击左侧“Component Mode”按钮——点击“P”按钮——在输入

1、并不是字真在移动，只是每次显示的图像不一样的，连续显示16次出来就是移动。比如上下移动，有个函数能显示一个字模数组。把“西”的整个字的字模放到这个数组显示的是西字，把“安”放进去就是安字。把西字16行的

用汇编语言完全可以实现。 第一步：先制作字库，少量汉字可以利用画笔工具，在画笔上写上16*16的汉字（最好是宋体），在放大功能下查看每个像素，黑色为1，白色为0，按照列或行依次读取。一个汉字的点阵用32个字节表示。 第二步：将上述汉字点阵制成表格，采用查表法获取需要显示的汉字点阵。 第三步：依据字库提取时的顺序，采用扫描驱动的方式依次在行和列上输出点阵。

74hc595要用四片 行列扫描 把两组（一组两片）的锁存脉冲接在一起。 然后把第一片的Q7‘接入第二片的SDA。另外把每组SCK接在一起。 十六位的移动是只 你往595里送个数据。那么595就会把最先送入的数据丢掉。然后整体向前移一位。 另外要注意。OE要接地。而且需要输出的时候锁存要产生一个上升。
