H7使用emwin5.44无法旋转屏幕，竖屏显示一切正常，切换到横屏模式就显示乱码了屏幕是无法硬件旋转的，只能通过软件实现，有点搞不懂emwin的实现方式。

横屏乱码

竖屏正常

下面是内存大小，使用的3缓冲。
#define GUI_NUMBYTES  (1024) * 8192*2 //8192

#define NUM_BUFFERS    3 /* Number of multiple buffers to be used */
#define NUM_VSCREENS    1 /* Number of virtual screens to be used */

因为我需要显示图片旋转的动画效果，所以使用的内存设备，然后发现
使用GUI_SetOrientation(GUI_SWAP_XY | GUI_MIRROR_X);设置屏幕旋转后
必须要WM_EnableMemdev(WM_HBKWIN);
这样横屏就能显示画面了，但是问题是图片显示很卡，竖屏刷新需要60ms,横屏竟然要超过560ms。

  GUI_Init();

	GUI_SetOrientation(GUI_SWAP_XY | GUI_MIRROR_X);

  /* Enable multibuffering for memory device animation */
  GUI_MEMDEV_MULTIBUF_Enable(1);
	
	/* Enable Window Manager Multibuffering */
  //WM_MULTIBUF_Enable(1);

#if GUI_SUPPORT_MEMDEV
  WM_SetCreateFlags(WM_CF_MEMDEV);
#endif
  WM_EnableMemdev(WM_HBKWIN);

刷新的多大图片，emWin的输出颜色格式是配置的565吧

60ms有点慢，要搞到10ms以内，使用存储设备绘制方式，就是把你的图片绘制到存储设备里面，然后调用存储设备的API刷新。

60ms有点慢，要搞到10ms以内，使用存储设备绘制方式 ...

1、输出是565

[C] 纯文本查看 复制代码

#define COLOR_CONVERSION_0    GUICC_M565 
#define DISPLAY_DRIVER_0      GUIDRV_LIN_16

2、我用了多个内存设备，图片和网格都是创建的不同的内存设备，然后在统一显示出来

是不是你的三缓存没有正常运行。有这个可能。

1、输出是565
[mw_shl_code=c,true]#define COLOR_CONVERSION_0 GUICC_M565
#define DISPLAY_DRIVE ...

绘制方式跟没有使用存储设备的速度是一样的，你这里仅仅是解决了整体绘制问题。

在WM_PAINT里面不要做任何额外的操作，仅仅是绘制。
