1. Reading from USB Devices To read data from a USB device, you can use the following code snippet: import usb.core import usb.util device = usb.core.find(idVendor=0x1234, idProduct=0x5678) if device is None: print("Device not found") ...
python Usb转串口环境安装及例子 大家好,这周我出差~~ 之前在调试python串口的时候也费了一些功夫,首先是搭建Python串口环境;之后是在网上找的Demo无法运行,最后是看官网的资料才入的门。。。 可爱的图标~~ 一.安装Python serial pip install pyserial 如果没有安装 python pip,执行 sudo apt install python-pip ...
