The full English name of SPI is Serial Peripheral Interface, which, as the name suggests, is a serial peripheral interface.SPI is a synchronous serial communication interface specification primarily used for short-distance communication in embedded systems.This interface was developed by Motorola in the mid-1980s and has since evolved into an industry standard.SPI is a high-speed, full-duplex, … Read more
1. Overview of SPI Communication SPI (Serial Peripheral Interface) is a synchronous serial communication protocol developed by Motorola (now NXP), primarily used for short-distance, high-speed communication between master and slave devices. Its features include full-duplex transmission, master-slave architecture, and no complex protocol layers, making it widely used in embedded devices such as memory (e.g., Flash), … Read more
1. Introduction to SPI SPI, which stands for Serial Peripheral Interface, is a synchronous serial communication protocol originally defined by Motorola for its MC68HCXX series processors. The SPI interface is primarily used for communication between EEPROMs, FLASH memory, real-time clocks, ADCs, as well as digital signal processors and digital signal decoders. SPI is a high-speed, … Read more
Introduction Hello everyone! Today, I want to share an exciting technology for engineers in the industrial communication field—PLC Protocol Penetration. Don’t be intimidated by this technical term, I will unveil its mysteries in the most relatable way.Imagine: PLCs in the workshop can directly “talk” to cloud servers, and devices from different brands can collaborate seamlessly … Read more
Click the aboveblue text to follow us In embedded systems, the Serial Peripheral Interface (SPI) and its extensions (such as DSPI and QSPI) are widely used for high-speed communication with external devices (such as sensors, memory, LCD controllers, etc.). The main differences are as follows: 1 SPI SPI (Serial Peripheral Interface) is a full-duplex synchronous … Read more

Introduction HTTP GET requests are one of the most common request methods in web development, used to send data to the server to retrieve resources. Meanwhile, header information plays a crucial role in HTTP requests, helping us control the state and format of data transmission. This article will detail how to send HTTP GET requests … Read more
I’ve seen someone ask this online, so I would like to share my answer. The person asking further elaborated: If I treat the server’s HTML, CSS, images, etc. as files transferred to the client and then assemble them for display, can I achieve the functionality of a webpage? This is a seemingly simple question that … Read more
