【问题描述】：
我正在使用 Vector CANoe 15.1 的演示版，目前，我已经成功创建了两个节点和两个面板。我创建了一些可以控制一些 LED 的按钮。我的想法是我想使用计时器，这样当我按下按钮时，我的 LED 会以 1Hz（1 秒）的频率闪烁。我设法让它在 5 个点火状态中的 3 个中工作，但在其他 2 个中却没有，即使我使用了相同的代码。也许如果我向您展示我的代码，您会更好地理解我。

当点火=0 或 1 时，只能作为 hazardLights 工作（左右同时闪烁）。问题是当我按下 HazardSwitch 时，LED 会亮起，但不会闪烁。我将附上一张包含图形的照片。前几秒钟，它应该如何工作（因为它在点火 = 2 或 3 或 4 时工作），然后你可以看到它在点火 = 0 或 1 时是如何工作的。
