51单片机带字库12864液晶动态汉字显示C语言源程序2009-10-17 19:36实验芯片为:AT89S52,带字库液晶屏:12864,实现的目的:动态一个汉字一个汉字显示。

其实和显示汉字的程序一样,只是稍做一下修改即可。

C语言源程序如下:#include <stdio.h>#include <math.h>#include <reg52.h>#include <string.h>sbit RS=P2^4;sbit WRD=P2^5;sbit E=P2^6;sbit PSB=P2^1;sbit RES=P2^3;void TransferData(char data1,bit DI);void delayms(unsigned int n);void delay(unsigned int m);void lcd_mesg003(unsigned char code *addr1);unsigned char code IC_DAT[]={"我是一个中国人啊"};void initinal(void){delay(40);PSB=1; //并口工作模式delay(1);RES=0; //复位delay(1);RES=1; //复位置高delay(10);TransferData(0x30,0);delay(100);TransferData(0x30,0);delay(37);TransferData(0x08,0);delay(100);TransferData(0x10,0);delay(100);TransferData(0x0C,0);delay(100);TransferData(0x01,0);delay(10);TransferData(0x06,0);delay(100);}void main(void){while(1){initinal();//调用LCD字库初始化程序delay(100);lcd_mesg003(IC_DAT);}}void lcd_mesg003(unsigned char code *addr1){unsigned char i;//第一行TransferData(0x80,0);delay(100);for(i=0;i<16;i++){TransferData(*addr1,1);addr1++;delayms(50);}}void TransferData(char data1,bit DI) //传送数据或是命令,当DI=0时,传送命令,当DI=1时,传送数据{WRD=0;RS=DI;delay(1);P0=data1;E=1;delay(1);E=0;}void delayms(unsigned int n){unsigned int i,j;for(i=0;i<n;i++)for(j=0;j<2000;j++);}void delay(unsigned int m){unsigned int i,j;for(i=0;i<m;i++)for(j=0;j<10;j++);}原理就是在显示每个汉字的时候加了一个延时程序,当然可以用定时器来实现,这样的话,不占用CPU处理时间。

tlc0832程序(C语言)这是调试好的tlc0832程序,用12864液晶显示,输入电压为0~5V,数字量为0~255。

模拟量显示的不是实际电压,只是为了说明问题而取数字量的0.02倍送到液晶显示。
