	{
		for(j=0;j<480;j++)
		lcdwritedata(Color);   
	}
}

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

STM32F407VET6的OTM8009_800X480屏幕驱动移植

很久之前搞了块OTM8009_800X480屏幕，同时还搞了块STM32F407VET6核心板，问题是这两个tft接口一个32针，一个34针，不能直接插，所以一直没搞。最近心血来潮，搞了下，好久没搞这方面东西，差点坑了自己。这方面其实驱动是有的，改改就可以了 先说参考，基于http://www.lcdwiki.com/zh/3.97inch_16BIT_Module_OTM8009A_SKU:MRB3971这个的stm32改就可以，这个里面有个F407ZGT6的驱动，同时也参考了原来淘宝卖家提供的库.

调试OTM4001A液晶驱动的一点心得

这几天调试一块以OTM4001A作驱动芯片的LCM模组，调试完毕后，终于有结果OK了。之前对这块一直用的不太透彻，恰好趁这次摸清楚了。需要注意的几点记录如下： （1）关于信号类型的片选。在很多LCD芯片规格书上都有关于信号片选的描述，如M2/M1/M0，典型如下： 如上图，上面的三个M接口脚是有连接线直接连到主板接口上的，至于是高还是低，可以由主板硬件限定死，另一方面也可以由LCM模组自身
