2G 移动通信系统最具代表性的是欧洲的全球移动通信系统(Global System for Mobile Communication,GSM),它使得全球范围内的漫游成为可能,并成为世界上最广泛使用的标准之一。 随着互联网的发展,人们对数据业务的需求也越来越高。为了提高数据传输速率,在 2G 系统的基础上又出现了一些增强技术,如通用分组无线服务(General...
I2C is a communication bus designed by Philips, for chips to communicate with each other on a PCB. It is commonly used, however, for connecting sensors, such as the two examples later in this instructable and port expanders, because you can have multiple devices on the same two pins. 步骤...

在串行链路上,Modbus协议有两种传输模式——ASCII模式和RTU模式。其中,ASCII(AmericanStandard Code for Information Interchange)为美国国家信息交换标准编码,RTU( Remote Terminal Unit)为远程终端设备。所以RTU通信就是通过模拟远程终端设备读写寄存器。 RTU通信我们需要的辅助工具是VSPD(Virtual Serial Port Driver 9.0 ...

The socket module serves as the cornerstone for network communication, supporting both TCP and UDP protocols. he asyncio library enables asynchronous network operations, while paramiko provides SSH functionality. Common networking patterns: TCP server setup server = socket.socket(socket.AF_INET, socket....
When using a long connection, if there is no communication for a long time, it may be considered offline by the other end, resulting in disconnection. Therefore, in business scenarios, the module sends a packet of data to the other end at a fixed period o keep the long connection alive....
Sometimes we need to exchange some data with another microconrtoller in close range, then we can use I2C for this job, even better, with MicroPython, we can do it in less than 5 lines of code, here is how it's done on ameba RTL8722 from Realtek, Material
