In Python, you can use the pyserial library to read USB data.<\/p>\n

Firstly, you need to install the pyserial library. You can install it using the following command:<\/p>\n

pip install pyserial\r\n<\/code><\/pre>\n
The steps for reading USB data are as follows:<\/p>\n
    \n
  1. Import the pyserial library.<\/li>\n<\/ol>\n
    import<\/span> serial\r\n<\/code><\/pre>\n
      \n
    1. Create a serial port object:<\/li>\n<\/ol>\n
      ser = serial.Serial('\/dev\/ttyUSB0'<\/span>, 9600<\/span>)  # \u6839\u636e\u5b9e\u9645\u60c5\u51b5\u4fee\u6539\u4e32\u53e3\u53f7\u548c\u6ce2\u7279\u7387<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Read data:<\/li>\n<\/ol>\n
        data = ser.read()  # \u8bfb\u53d6\u4e00\u4e2a\u5b57\u8282\u7684\u6570\u636e<\/span>\r\n<\/code><\/pre>\n
        Or<\/p>\n
        data = ser.readline()  # \u8bfb\u53d6\u4e00\u884c\u6570\u636e\uff08\u4ee5\u6362\u884c\u7b26\u7ed3\u5c3e\uff09<\/span>\r\n<\/code><\/pre>\n
          \n
        1. Close the serial port.<\/li>\n<\/ol>\n
          ser.close()\r\n<\/code><\/pre>\n
          The complete sample code is provided below:<\/p>\n
          import<\/span> serial\r\n\r\nser = serial.Serial('\/dev\/ttyUSB0'<\/span>, 9600<\/span>)\r\n\r\nwhile<\/span> True<\/span>:\r\n    data = ser.readline()\r\n    print<\/span>(data)\r\n\r\nser.close()\r\n<\/code><\/pre>\n
          In the code above, ‘\/dev\/ttyUSB0’ is the path to the USB serial device, which can be modified according to the actual situation. 9600 is the baud rate, which can also be modified according to the actual situation. Then, continuously read and print out the data using a loop.<\/p>\n","protected":false},"excerpt":{"rendered":"
