关于索引的问题

int main(void)

 {

OLED_ShowString(0,0,"nihao"); 主函数的显示程序

 }

void OLED_ShowString(u8 x,u8 y,const u8 *p)

{

#define MAX_CHAR_POSX 122

#define MAX_CHAR_POSY 58          

    while(*p!='\0')

    {       

        if(x>MAX_CHAR_POSX){x=0;y+=16;}

        if(y>MAX_CHAR_POSY){y=x=0;OLED_Clear();}

        OLED_ShowChar(x,y,*p,16,1);  

        x+=16;

        p++;

    }  

}

void OLED_ShowChar(u8 x,u8 y,u8 chr,u8 size,u8 mode)

{          

u8 temp,t,t1;

u8 y0=y;

chr=chr-' ';                            //得到偏移后的值    这个是得到ASCII码偏移后的地址    但是我现在要做的是得到汉字的偏移后的地址   

    for(t=0;t<size;t++)

    {   

if(size==12)temp=asc2_1206[chr][t];  //调用1206字体

else temp=asc2_1608[chr][t]; //调用1608字体                          

        for(t1=0;t1<8;t1++)

{

if(temp&0x80)OLED_DrawPoint(x,y,mode);

else OLED_DrawPoint(x,y,!mode);

temp<<=1;

y++;

if((y-y0)==size)

{

y=y0;

x++;

break;

}

}    

    }          

}

我想弄成的效果

int main(void)

 {

OLED_ShowString(0,0,"你好"); 主函数的显示程序

 }

索引值 是根据你字库来的。

这个是我自己建的那个数组，但是我不知道该怎么弄了

原子哥是这个子函数吗？

是的,但是前提是你要有做好的字库,存放在SPI FLASH,才可以.
