This is the 256th content shared by the platform.In process control systems, sensor transmitters collect data such as pressure, temperature, flow, and level, and send this information to a Programmable Logic Controller (PLC) or Distributed Control System. These transmitters rely on 4-20mA signals to send data to the controller. Despite the emergence of standards like … Read more
Recently, I spent some time organizing the verification of the SPI module in the USI module of the WUJIAN100 project. Here, I would like to share some of my thoughts and methods. Basic Introduction to the Design Functionality of the USI Module USI (Unified Serial Interface) is a combined module that includes UART, SPI, and … Read more
Hug pid:131183771 by:White It is still discussed in the Microelectronic System Click here to view the Microelectronic System review: SPI The specific transmission details of SPI are clearly explained there, so I will briefly mention it here without going into detail.

Ensuring system scalability is one of the core goals of our architectural design work. There are many ways to achieve scalability, and the JDK itself has a built-in SPI (Service Provider Interface) mechanism to help developers dynamically load various implementation classes, as long as these implementation classes follow certain development specifications. On the other hand, … Read more
1. Comparison of Communication Speeds: SPI, I2C, UART SPI > I2C > UART 1. Synchronous communication > Asynchronous communication; 2. In synchronous communication, a clock line must connect both ends of the transmission; 3. All are serial communication methods, while parallel communication is used for internal storage communication, such as flash; 4. The suitable transmission … Read more
