画UCGUI界面的过程中，STM32的定时器进不了中断服务函数！！！！！！

口天土立口

如题，我注释了画UCGUI界面的函数，我的定时器中断服务函数就能进入了，但我在画UCGUI界面的过程中，我无法进入定时器中断服务函数！搞不懂这个是什么问题！

部分UCGUI画界面函数如下：

1.（画如下这个界面的过程中，无法进入定时器中断）：

[mw_shl_code=c,true]void Draw_Check_Screen(void) { int rate = Heart_Rate; int height = Height; int west = West; int east = East; if(Screen_Change == 1) //??????????????±??? { GUI_ClearRect(0,0,128,128);//????±??°???????? } Draw_Header(); //???????? GUI_DrawBitmap(&bm30x30heart_rate,10,30);//??????????±ê GUI_DrawBitmap(&bm30x30navigation,10,80);//?????¨????±ê GUI_SetColor(GUI_BLUE); GUI_DrawLine(10,67,117,67);//???????????±?? GUI_SetColor(GUI_WHITE); GUI_SetFont(&GUI_Font8x8);//?è??×??? GUI_GotoXY(50,40);//?è???±?°??±????? GUI_DispDecMin(rate);//?????????? GUI_GotoXY(50,85);//?è???±?°??±????? GUI_DispDecMin(east);//?????????????? GUI_DispChars('E',1); GUI_GotoXY(90,85);//?è???±?°??±????? GUI_DispDecMin(west);//?????????????? GUI_DispChars('W',1); GUI_GotoXY(50,103);//?è???±?°??±????? GUI_DispDecMin(height);//?????????????? GUI_DispChars('H',1); }[/mw_shl_code]

2.（画如下这个界面的时候，进不了定时器中断服务函数）：

[mw_shl_code=c,true]void Draw_Phone_Screen(void) { char string1[15] = "Calling..."; char string2[15] = "Your telegram"; char string3[15] = "On the phone"; char ac[] = "Select number:"; char xPosition1 = 20; char yPosition1 = 68; char xPosition2 = 20; char yPosition2 = 88; char xPosition3 = 20; char yPosition3 = 108; unsigned char i; char phone[11] ; //?????????????°???? for(i = 0;i <11;i++) { phone = Phone_Number; //???????°???? } if(Screen_Change == 1) //??????????????±??? { GUI_ClearRect(0,0,128,128);//????±??°???????? } Draw_Header();//???????? switch (K1_Count) { case PHONE_DIALING : //????????????

请各位大神支招！万分感谢！

正点原子

找到产生这个问题的原因了，是如下这个函数导致的问题：

GUI_AA_FillPolygon()；

定位的到这个函数，函数的原型如下：

[mw_shl_code=c,true]/********************************************************************* * * GUI_AA_FillPolygon */ void GUI_AA_FillPolygon(/*const*/ GUI_POINT* pPoints, int NumPoints, int x0, int y0) { GUI_LOCK(); #if (GUI_WINSUPPORT) WM_ADDORG_AA(x0,y0); WM_ITERATE_START(NULL); { #endif /* Variables in MEMDEV module (with memory devices only) */ #if GUI_SUPPORT_MEMDEV if (GUI_Context.pDeviceAPI->pfFillPolygonAA) GUI_Context.pDeviceAPI->pfFillPolygonAA(pPoints, NumPoints, x0, y0); else #endif _FillPolygonAA (pPoints, NumPoints, x0, y0); #if (GUI_WINSUPPORT) } WM_ITERATE_END(); #endif GUI_UNLOCK(); }[/mw_shl_code]

我的 GUI_WINSUPPORT 定义为 0，GUI_SUPPORT_MEMDEV 定义为 1 ，但我的是 裸机UCGUI，所以里面的 GUI_LOCK(); 和 GUI_UNLOCK(); 是空函数体，不影响！
唯一会影响的就是GUI_SUPPORT_MEMDEV 这个定义！
请问各位大神，具体是什么原因？

只要我使用了抗锯齿函数，都无法进入中断服务函数，但改成非抗锯齿函数画界面，都可以进入定时器中断服务函数！

现在还是不知道为什么会这样！
