上传一直失败,人快崩..求问各位大佬出现这种状况咋整,网上说可能驱动没装或者端口被占用,可我看都是好的,换过别的也都是can‘t set com-state for… 这到底要咋办啊现在连个blink都上传不了
Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: - Use the onboard LED. - Note: Most Arduinos have an on-board ...
根据您的安装,您可能可以直接添加新的Statechart模型,或者可能必须使用Other,选择Yakindu,然后选择Statechart模型。现在,您应该看到的是第二张图片:一个进入状态和一个名为 StateA 的通用第一状态。 左侧的文本框允许您声明相关的事件和变量状态图,右边的区域是图形状态图编辑器。 我们将需要一个事件:按钮。双击左侧的...
