EMWIN窗口不刷新

ccschen

系统是FREERTOS,屏用的SSD1306,显示区域分成了两部分，上面一小块做状态栏显示，是个子窗口，在回调中的EMWIN的软件定时器中让窗口无效来刷新屏幕，下方是一个WINDOW，也是用定时器来刷新显示。时间不定，设备可能几天，也可能几十天才不刷新，由于不容易出现此情况，没连接仿真器，所以不知道是什么原因。RTOS没死，其它外设工作都好好的，其它EMWIN界面都能调出来显示。状态栏和窗口都不刷新。


代码根据ST官方的示例改的。大概代码如下：

  WM_SetCreateFlags(WM_CF_MEMDEV);   
    GUI_EnableAlpha(1);
    WM_MULTIBUF_Enable(1);

窗口存储设备和三缓冲，二选一，两个都定义会导致，之前版本实测，会导致仅存储设备起作用。


其它的地方要测试下程序才行。

WM_SetCreateFlags(WM_CF_MEMDEV);   
    GUI_EnableAlpha(1);
    WM_MULTIBUF_Enable(1);

意思是只需要WM_SetCreateFlags(WM_CF_MEMDEV);        就可以了？搞不懂，为什么定时器中途会挂掉。。。

修改后解决了吗

很难说，目前没出，即使要出问题，也不知道什么时候出了，这个不像那种随时可复现的问题。反正现在老化起的。       
现在只用了MEMDEV那个。
现在都在定时器里面这样干了。
WM_InvalidateWindow(WM_GetClientWindow(pMsg->hWin));
/* Refrish real time display */   
WM_InvalidateWindow(pMsg->hWin);

然后新建定时器都是在case WM_INIT_DIALOG:里面建立的。       

然后现在在弄FREERTOS+GUIX，OLED,SPI,可想而知306，GUI的定时器和任务都在运行，屏幕上就是不出主界面。这样时间成本最小。之前是FREERTOS+STEMWIN.
反正想多个方案做备份，修改后需要长时间测试，不知道什么时候会出问题。。

很好，GUIX主界面出来了。。。哈哈哈。。。
