}

补充部分(otm8009中显示图片的代码)
需要注意gImage为存放图片数据的数组，可以把图片放在单片机Flash中或者SD卡，一边读取一边刷新屏幕。

void LCDdisplay()
{unsigned int lcd;unsigned long p=0;LCD_SetWindows(0,0,480-1,800-1);for(p=0;p<460800;p++)        //卖萌图片占460800个字节{lcd=gImage[p+1];//赋值高8位RGB数据lcd<<=8;              //RGB数据移位lcd|=gImage[p]; //赋值低8为RGB数据p++;lcdwritedata(lcd);  }for(p=0;p<153600;p++)    //剩下部分填充黑色{lcdwritedata(BLACK);}
}

(三)需要改进的地方及不足

程序改了很多次，使用HAL库来操作GPIO速度最快600KHZ，后面改成使用底层的位带操作速度提升至1.67MHZ，但是还是无法达到播放动画的帧数。
全屏刷图需要8004802（RGB565格式）= 768000字节
使用HAL库操作GPIO 耗时:768000/2/600KHZ = 0.64秒 一帧
使用底层位带操作GPIO 耗时:768000/2/1670KHZ = 0.23秒 一帧
而需要动画连贯至少需要24帧/秒 所以必需在0.04秒刷完一帧才能保证动画流畅
但是我现在还不会使用STM32中的FMC接口来自动与屏幕通信，还需继续学习
