使用stm32在lcd上隨意顯示漢字
怎樣在lcd彩屏上顯示漢字，我們習慣使用漢字型檔，也有很多自己做一個漢字型檔，我就習慣這一種。
介紹一下 我做的顯示 “ 同一個世界！ 同一個夢想！”
首先 在網上下一個提取點陣的的軟體生成自己的字型檔，
const struct typFont16 Font16lib[]={
"夢", 0x0410,0x0410,0x7F7E,0x0C10,0x1638,0x7554,0x24D3,0x0430,

};
漢字的點陣結構體格式為：
typedef struct typFont16 // 漢字字模資料結構
{
uc8 Index[2]; //漢字
uc16 Msk[16]; //字模
} typFont16;
在uc8 index【2】裡存放漢字 將會是以國標碼的格式儲存 ，我們就是根據這個搜尋要顯示的字在什麼位置
void hz_write(u8 ox,u16 oy,uc8 *p)
{
unsigned char i,x=0;
//unsigned int x,y;
ox=ox*16;
while(*p)
{
i=0;
while(1)
{
if( (*p==Font16lib[i].Index[0]) && (*(p+1)==Font16lib[i].Index[1]))
{ //找到漢字,顯示
//addr=oy*(320/8)+ox+SCREE_ONE_ENDADDR;
//hz(addr,Font16lib[i].Msk);
LCD_DrawCharhanzi(ox, oy, Font16lib[i].Msk);
oy-=16;
oy+=16; //下一個顯示
p+=2;
//找下一個漢字
x++;
if((x == 20))//|| (oy == 15))
{
ox += 16;
oy = 319;
x = 0;
}
oy-=16;
break;
}
i++; //下一個漢字型檔
if(i >= 9) //超出字型檔範圍
{
p+=2; //找下一個漢字
break;
}
}
}
}
