OLED显示一张图片

1.思路:

        void Oled_Show_Image(unsigned char *image) //
{
   unsigned char i;    //-128 ~ 127位
   unsigned int j;    //j要重新定义，因为要到达图片的最后一位
                                       //行 i没有问题，j有问题 i为1时，j要从128开始这样子才会刷屏
   for(i=0;i<8;i++)
   {
       Oled_Write_Cmd(0xB0 + i);   //page0 -- page7

       //每个page从第0列开始
       Oled_Write_Cmd(0x00);
       Oled_Write_Cmd(0x10);

       //每个page从0列到127列，依次写入0，每写入数据，列地址自动偏移
       for(j = 128*i;j<(128*(i+1));j++) //列 i等于0的时候，j<128 //i到7的时候 i+1=8, 其实就是j<8（i+1）最后j要<128*8
       {
           Oled_Write_Data(image[j]);
       }
   }

}

bug:

code unsigned char bmpImager[]={}；数组后面要加分号
