用LCD12864怎么样才能象显示字符串那样显示中文中文

lvshaohui · 发表于 2007-7-28 13:56:51

比如说，显示“我爱单片机”，用一个函数显示；

不想象这样用：

write_ch(wo);

write_ch(ai);

write_ch(dan);

write_ch(pian);

write_ch(ji);

TonyCai · 发表于 2007-7-28 13:59:42

建议自己做个子函数，想怎么显示就怎么显示

lanshuitianxia · 发表于 2007-7-28 14:05:18

带中文字库吗，带字库的就简单多了。

lvshaohui · 发表于 2007-7-28 14:14:10

我想这样做：

比如显示“我爱单片机”，先在定义的数组查寻字符‘我’，如果查到，就显示‘我’后面的那32个数据（假定显示的是16X16汉字）,如下：

const unsigned char hanzi[]={‘我’，0X11，0X12。。。。。。。};

但是编译时有错。这是怎么回事？请问！

这要看你的屏是否带汉字库,如过带汉字库就简单多了,如果没带,就要先取得汉字的字模,然后写进去就可以了

我还是说个简单的，不然大家能把楼猪吓蒙，现打的，ST7920，带字库

/***** SPI 发送一个字节 ****/
void LCD_Send_Byte(uchar dat)
{
....
....
}

/****** 发送数据 ******/
void LCD_Send_Data(uchar dat)
{
LCD_Send_Byte(0xFA);
....
....
}

/***** 发送命令 *****/
void LCD_Send_CMD(uchar cmd)
{
LCD_Send_Byte(0xF8);
....
....
}

void Show_Str(uchar *ptr,uchar addr,uchar length)
{
uchar i;
uchar command_data;

command_data = addr;
LCD_Send_CMD(command_data);
Delay(100);
for(i = 0; i < length; i++)
{
      command_data = *ptr;
      LCD_Send_Data(command_data);
      ptr++;
}
}

void main(void)
{
Initial.....
Show_Str("我爱单片机ABC123",0x80,16)
while(1);
...
}

这样就OK，但没判断字符边界什么的，理解容易。

怎么都是在贴代码呢。。。。。

用LCD12864怎么样才能象显示字符串那样显示中文中文

阿莫论坛20周年了！感谢大家的支持与爱护！！
