程序基于各开发板的OLED显示实验例程修改而来，利用PCtoLCD2002生成“开” “发” “板”三个点阵库并存放在片内FLASH，该软件的取模方式与OLED实验例程ASCII字符集的取模方式一致[mw_shl_code=c,true]const u8 OLED_HZK_TBL[3][72]=

}; [/mw_shl_code]
整个程序最重要的是OLED_Show_Font()
[mw_shl_code=c,true]//在指定位置，显示一个24*24大小的汉字
//x,y :汉字的坐标
//index:汉字编号（在字库数组里面的编号）
void OLED_Show_Font(u16 x,u16 y,u8 index)
{
u8 temp,t,t1;
u16 y0=y;
u8 *dzk;
u8 csize=72; //一个24*24的汉字72字节
dzk=(u8*)OLED_HZK_TBL[index]; //得到汉字编号对应的点阵库
for(t=0;t<csize;t++)
{
temp=dzk[t]; //得到点阵数据
for(t1=0;t1<8;t1++) //按照从高位到低位的顺序画点
{
if(temp&0x80)OLED_DrawPoint(x,y,1);
else OLED_DrawPoint(x,y,0);
temp<<=1;
y++;
if((y-y0)==24) //对y坐标的处理，当y坐标距起始坐标差24个像素点，x坐标加1
{
y=y0;
x++;
break;
}
}
}
}[/mw_shl_code]
然后main.c函数中调用 OLED_Show_Font()
[mw_shl_code=c,true] OLED_ShowString(16,0,"ALIENTEK",24); //24*24字体
OLED_ShowString(28,24,"MiniSTM32",16);  //16*16字体
OLED_Show_Font(28,40,0); //开
OLED_Show_Font(28+24,40,1); //发
OLED_Show_Font(28+48,40,2); //板
OLED_Refresh_Gram();//更新显示到OLED    [/mw_shl_code]

OLED显示效果如图
