创建一个文件,然后通过创建一个例子`File@ class, 和调用FileSystem.open()(暗示你想创建程序的地方),来打开它。在"/tmp"(驻留在RAM,来保存闪存读/写电路的有限制的数值)保存程序。 void uploadScript() { File script = FileSystem.open("/tmp/wlan-stats.sh", FILE_WRITE); [Get Code] 用File.print(...

These pins are what we use to read and write information that has a range of values, such as the position of a dial, the distance of an object from an infrared sensor, or the brightness of an LED light. In addition to the digital and analog pins, there are connectors relating to the...
然后,我们使用ser.write方法向Arduino发送数据,并使用ser.readline方法从Arduino接收数据。最后,我们关闭了串口。 控制Arduino 接下来,我们将介绍如何使用Python编程来控制Arduino的输入和输出。 假设我们连接了一个LED到Arduino的数字引脚2上,并希望通过Python程序来控制该LED的开关。首先,我们需要在Arduino上编写一个简单的...
