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
In embedded systems, efficient data transmission is key to connecting processors with peripheral devices. SPI (Serial Peripheral Interface), as a high-speed synchronous serial communication protocol, has become the preferred solution for interactions with peripherals such as sensors, memory, and display modules due to its flexible configuration, full-duplex capability, and low-latency characteristics. This article will comprehensively … Read more
I2C Bus (Inter-Integrated Circuit）is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripherals. It is a widely adopted bus standard in the field of microelectronics control. It is a special form of synchronous communication, characterized by fewer interfaces, simple control methods, fewer device packaging forms, and high communication rates. The I2C … Read more
Search WeChat Jicheng Training JICHENGPEIXUN Serial port, short for serial port interface, is also known as serial communication interface or COM interface. Serial communication refers to a communication mode that uses a serial communication protocol to transmit data bit by bit over a single signal line. Serial ports are classified according to electrical standards and … Read more
Click the blue text to follow us 0. Introduction: Computer communication is divided into serial communication and parallel communication. Parallel communication: Typically transmits data bytes simultaneously using multiple data lines. Serial communication: Transmits data bytes one bit at a time over a single transmission line. Each has its own advantages and disadvantages: Parallel communication: Simple … Read more
Introduction to Serial Communication Classification Based on Data Transmission Direction Simplex: Data transmission only supports data transfer in one direction. Half-Duplex: Allows data to be transmitted in both directions. However, at any given time, data can only be transmitted in one direction, which is essentially a switched direction simplex communication; it does not require separate … Read more
