ID:222467 · 发表于 2017-7-26 15:24

用LCD1602的CGRAM显示自定义的汉字不知道哪里出错就是不显示求大神解答

#include<reg52.h>
sbit CE = P2^7;
sbit RW = P2^5;
sbit RS = P2^6;

unsigned char table[]=
{
0x1F,0x11,0x11,0x1F,0x11,0x11,0x1F,0x00,//日
0x0F,0x09,0x0F,0x09,0x0F,0x09,0x09,0x12,//月
0x04,0x0F,0x12,0x0F,0x0A,0x1F,0x02,0x02,//年
};

void Read_Busy()
{
unsigned char busy;
P0 = 0xff;
RS = 0;
RW = 1;
do{
CE = 1;
busy = P0;
CE = 0;
}while(busy>7);
}

void Write_Cmd(unsigned char cmd)
{
Read_Busy();
RS = 0;
RW = 0;
P0 = cmd;
CE = 1;
CE = 0;
}

void Write_Data(unsigned char dat)
{
Read_Busy();
RS = 1;
RW = 0;
P0 = dat;
CE = 1;
CE = 0;
}

void main()
{
int i;
Write_Cmd(0x01);//数据指针清零所有显示清零
Write_Cmd(0x38);//设置显示
Write_Cmd(0x0f);//开显示光标闪烁
Write_Cmd(0x06);//设置指针光标不移屏

Write_Cmd(0x41); //写入CGROM
for(i=0;i<24;i++)
{
Write_Data(table[i]);
}

Write_Cmd(0x80);//设置地址指针
Write_Data(0x00);
Write_Data(0x01);
Write_Data(0x02);
while(1);
}

楼主，你的等待液晶准备好的函数是不是有一点问题：/* 等待液晶准备好 */
void LcdWaitReady()
{
unsigned char sta;

LCD1602_DB = 0xFF;
LCD1602_RS = 0;
LCD1602_RW = 1;
do {
LCD1602_E = 1;
sta = LCD1602_DB; //读取状态字
LCD1602_E = 0;
} while (sta & 0x80); //bit7 等于 1 表示液晶正忙，重复检测直到其等于 0 为止
}

两处错误！

0x04,0x0F,0x12,0x0F,0x0A,0x1F,0x02,0x02,//年
};

void Read_Busy()
{
unsigned char busy;
P0 = 0xff;
RS = 0;
RW = 1;
do{
CE = 1;

CE = 0;
}while(busy>7);//while(busy>>7);
}

void Write_Cmd(unsigned char cmd)
{
Read_Busy();

}

void Write_Data(unsigned char dat)
