# Click the blue text to follow us and never miss exciting content Origin of SPI The SPI interface was first proposed by Motorola (now NXP) for high-speed data transfer between processors and peripheral devices. Due to its simplicity, efficiency, and low resource consumption, it quickly gained widespread adoption and became one of the most … Read more
👇Click to follow for daily technical insights!👇 1 Introduction SPI: Serial Peripheral Interface, a serial peripheral interface. SPI was developed by Motorola around 1985 and is a synchronous serial interface suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors … Read more
Introduction The previous article detailed the SPI module under the Autosar architecture diagram, but did not cover the SPI communication bus. This article is a repost of what I consider to be a well-written introduction to the SPI communication protocol for your reference. Reference Articles: AUTOSAR-MCAL–Detailed Explanation of SPI Module (I) AUTOSAR-MCAL–Detailed Explanation of SPI … Read more
Click the blue text Follow us 1. Clock Synchronization Issues in Serial Data Sending serial data (such as USB, UART, I2C, SPI, etc.) is done over a single data bus. If a continuous stream of 01 signals is sent to the receiving device over this bus, the difference in clock frequencies between the sender and … Read more
Hello everyone, I am Daji Zong, and today I will talk about two commonly used communication buses on microcontrollers: SPI and I2C. As the names suggest, SPI stands for Serial Peripheral Interface, while I2C stands for Inter-Integrated Circuit Bus. Both are common methods for chip-to-chip communication. Introduction to SPI The SPI bus consists of four … Read more
Comparison of I2C and SPI Communication Protocols In microcontroller development, peripheral expansion is an inevitable task, such as connecting sensors, displays, or memory. Both I2C and SPI are commonly used communication protocols, each with its own advantages and disadvantages, suitable for different scenarios. This article will help you understand the basic concepts, hardware connections, code … Read more
Communication between electronic devices is like communication between humans, as both parties need to speak the same language. In electronic products, these languages are called communication protocols. Previously, I shared separate articles on SPI, UART, and I2C communication; this article compares them. Serial vs Parallel Electronic devices communicate by sending data bits. A bit is … Read more
1. Qiu Qianzhang’s Lightness Skill: UART In “The Legend of the Condor Heroes”, Qiu Qianzhang says, “UART is like my lightness skill, gliding over the water to cross the river.” To cross the river (communication), one must set up hidden stakes in advance, and while moving, the steps must be fixed according to the distance … Read more
