LCD写入数据
void TFT_WriteData(u16 dat)
{
TFT->TFT_DATA = dat<<8;
}

void TFT_WriteData_Color(u16 color)
{
TFT->TFT_DATA = color&0xff00;
TFT->TFT_DATA = color<<8;
}

初始化LCD屏这个很长，直接使用就行
void TFT_Init(void)
{
uint16_t i;

TFT_GPIO_Config();
TFT_FSMC_Config();

设置要操作的窗口范围 xStart：窗口起始X坐标 yStart：窗口起始Y坐标 xEnd：窗口结束X坐标 yEnd：窗口结束Y坐标

将LCD清屏成相应的颜色
void TFT_ClearScreen(uint16_t color)
{
uint16_t i, j ;

TFT_SetWindow(0, 0, TFT_XMAX, TFT_YMAX); //作用区域
for(i=0; i<TFT_XMAX+1; i++)
{
for (j=0; j<TFT_YMAX+1; j++)
{
TFT_WriteData_Color(color);
}
}
}
