Follow the steps to enable emWin multiple buffers:

4. add GUIConf2.c to sample project
5. increase main.c frame buffer size

#ifdef __ICCARM__
#pragma data_alignment = 32
UINT8 u8FrameBuf[XSIZE_PHYS*YSIZE_PHYS*2*3];
#else
UINT8 u8FrameBuf[XSIZE_PHYS*YSIZE_PHYS*2*3] __attribute__((aligned(32)));
#endif

复制代码

6. enable multiple buffers after GUI_Init():

GUI_Init();
