X3+ILI9341屏幕显示问题

kotonv510

我使用的安富莱X3开发板，然后外接了一块ILI9341的LCD屏，简单的stemwin程序

void MainTask(void)
{
        
    GUI_Init();

    WM_SetDesktopColor(GUI_GREEN);    /* Automacally update desktop window */
    WM_SetCreateFlags(WM_CF_MEMDEV);  /* Use memory devices on all windows to avoid flicker */
    WM_EnableMemdev(WM_HBKWIN);

    printf("ok ST GUI_Init is ok!!!!!!!\r\n");

    GUI_SetBkColor(GUI_RED);
    GUI_UC_SetEncodeUTF8();

    GUI_SetFont(&GUI_Font8x16x1x2);

    printf("ok GUI_DispStringAt is display!!!!!!!\r\n");
   GUI_SetColor(GUI_GREEN);

    GUI_DispStringAt("hello armfly!", 10, 20);

    printf("ok ST emWin init is ok!!!!!!!\r\n");
    while(1)
    {
        GUI_Delay(10);
        GUI_Exec();
    }
}

显示一闪就没了，这是什么原因

把这个函数注释掉 WM_SetDesktopColor(GUI_GREEN);    /* Automacally update desktop window */
