标题: 怎么用LCD12864显示取模的汉字？
我用的带字库的LCD12864，想显示取模的汉字，现象是一行四个汉字，有两行~哪位可以教我一下，有程序更好

下面的是显示图片的程序你改一下就能显示文字了：

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

#define uchar unsigned char
#define uint  unsigned int
/*12864端口定义*/
#define LCD_data  P0          //数据口
sbit LCD_RS  =  P3^5;          //寄存器选择输入
sbit LCD_RW  =  P3^6;          //液晶读/写控制
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;
