First, you need to determine the type and connection method of the external device, such as serial ports, USB, Bluetooth, etc. Then, based on the communication protocol and interface of the external device, write the corresponding Python program to establish the connection and communication.<\/p>\n<p>Here is an example code in Python to connect to a serial device:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">import<\/span> serial\r\n\r\n<span class=\"hljs-comment\"># \u6253\u5f00\u4e32\u53e3<\/span>\r\nser = serial.Serial(<span class=\"hljs-string\">'COM1'<\/span>, <span class=\"hljs-number\">9600<\/span>, timeout=<span class=\"hljs-number\">1<\/span>)\r\n\r\n<span class=\"hljs-comment\"># \u53d1\u9001\u6570\u636e<\/span>\r\nser.write(<span class=\"hljs-string\">b'Hello, World!'<\/span>)\r\n\r\n<span class=\"hljs-comment\"># \u8bfb\u53d6\u6570\u636e<\/span>\r\ndata = ser.readline()\r\n<span class=\"hljs-built_in\">print<\/span>(data)\r\n\r\n<span class=\"hljs-comment\"># \u5173\u95ed\u4e32\u53e3<\/span>\r\nser.close()\r\n<\/code><\/pre>\n<p>In the code example above, the Python serial module is used to establish a connection with a serial device. The serial.Serial() function is used to open the serial port, followed by using the write() method to send data, the readline() method to read data, and finally the close() method to close the serial port.<\/p>\n<p>You can choose the appropriate Python module and method to establish connection and communication based on the type of external device and communication method.
