Emwin 定时器工作若干时间后不能进 case WM_TIMER:
在window中，每秒刷新一次数据，创建定时器成功，刷新也正常，只是几小时，或者几天，几十天后，界面不刷新了。挂上仿真器后，也复现了现象，发现界面也能切换，界面切换回去，部分条件分支也是执行了的，但WM_TIMER就是进不去，不知道什么原因。
部分代码如下：
WM_SetFocus(pMsg->hWin);
hTimerTime = WM_CreateTimer(pMsg->hWin, ID_ACQ_TIMER_TIME, 1000, 0);
case WM_TIMER:
WM_InvalidateWindow(WM_GetClientWindow(pMsg->hWin));
/* Refrish real time display */
WM_InvalidateWindow(pMsg->hWin);//定时器消息，这里要特别注意，如果想要定时器周期性执行，而不是只执行一次，必须得调用重启定时器函数WM_RestartTimer()。在这个消息里面将桌面窗口无效，从而会触发窗口管理器去执行WM_PAINT消息，这样就实现了定时修改桌面窗口背景色。
WM_RestartTimer(pMsg->Data.v, 1000);
break;
刚才又试了下，将这个界面结束掉，重新进界面，又可以刷新了，重开界面会重新创建定时器的，难道定时器某种原因挂掉了？ ccschen 发表于 2022-9-8 23:11

这里怎么更新了两次，你的是框架窗口？仅更新客户区就行了。
WM_InvalidateWindow(WM_GetClientWindow(pMsg->hWin));
WM_InvalidateWindow(pMsg->hWin);
另外是不是更新内容很多，如果更新内容很多，使用局部区域更新的那个API方便些。

上次不是也不刷新么，就加了句，是重复了，测试了个多月，定时器就不刷新了。 是这样的，窗口128*64，上面一行做成的子窗口，用来显示状态，时间这些，下面就是主显示区域，都是WINDOW。子窗口里面有定时器，主窗口也有定时器。 之前状态栏那用这个函数 WM_CreateWindowAsChild，现在改成 WM_CreateWindow，不知道会有改善不。下面部分主界面都是用的GUI_CreateDialogBox。 ccschen 发表于 2022-9-9 15:07

这两个区别不大，你改用仅更新局部指定区域的API试试，另外你的这个分辨率只有128*64，很大概率不是更新上的问题，估计有地方实现有问题。 eric2013 发表于 2022-9-11 11:00

仅更新局部指定区域的API?
请明示？ eric2013 发表于 2022-9-11 11:00

关键是定时器中断不进了，不进WM_TIMER 状态栏参考ST官方的DEMO做的，刷新方式也是这样的。

已经解决了，就是在RTOS中定时发送事件给窗口，窗口再刷新，就不用窗口中的定时器了。
