標(biāo)題: 怎么用LCD12864顯示取模的漢字？
我用的帶字庫的LCD12864，想顯示取模的漢字，現(xiàn)象是一行四個(gè)漢字，有兩行~哪位可以教我一下，有程序更好

下面的是顯示圖片的程序你改一下就能顯示文字了：

#include <reg51.h>
#include <intrins.h>

#define uchar unsigned char
#define uint  unsigned int
/*12864端口定義*/
#define LCD_data  P0          //數(shù)據(jù)口
sbit LCD_RS  =  P3^5;          //寄存器選擇輸入
sbit LCD_RW  =  P3^6;          //液晶讀/寫控制
sbit LCD_EN  =  P3^4;          //液晶使能控制
sbit LCD_PSB =  P3^2;          //串/并方式控制
sbit wela =  P2^6;
sbit dula =  P2^7;
