emwin create their own window, and all interfaces are placed below WM_PAINT, Timer, always stuck, could not find the reason, last finding may be out of memory, the cause is found

create_basePage (); // redraw every background and title

Every time redraw the entire page and then no clear cause of insufficient memory, constantly try to find create_basePage (); WM_PAINT placed outside, can not draw a rectangle to set the background color, and the button listeners also a problem,

Finally only rewrite, after finished, WM_PAINT only need to place a rectangle, you need to be repainted control function can be achieved, and it will not have enough memory to learn a lesson!

Case the WM_PAINT: 
    GUI_Clear (); 
    GUI_DrawGradientV ( 0 , 0 , LCD_GetXSize (), LCD_GetYSize (), GUI_LIGHTGREEN, 0x71B33C );   // Gradient Hatch 
    GUI_SetPenSize ( . 1 ); // brush pixel. 1 
    GUI_SetColor (GUI_BLACK);   // brush color black 
    GUI_DrawRect ( 1 , 1 , 388 , 52 ); // draw a rectangle 

    // draw border 
    GUI_DrawRect ( 388 , 70 , 478 , 250 ); 

    // alarm bar
    GUI_DrawRect ( 388 , 125 , 478 , 184 ); 

    // frequency display column 
    GUI_DrawRect ( . 1 , 52 is , 388 , 270 ); 

    // data display field 
    GUI_DrawRect ( . 1 , 270 , 388 , 318 ); 

    // data columns 
    GUI_DrawRect ( 126 , 270 , 252 , 318 ); 

    // Videos start block
     // GUI_DrawRect (388, 220, 479, 319); 

    // redraw
    //重绘倒计时
    if(strlen(time_buffer)==0 || !strcmp(time_buffer, "00:00:00")){
        TEXT_SetText(WM_GetDialogItem(pMsg->hWin, ID_TEXT_7), "00:00:00");
