SPI Peripherals: The Bridge for High-Speed Synchronous Serial Communication

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

An Overview of UART Modes in STM32

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

Understanding STM32 Serial Communication

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

Detailed Explanation of UART Waveforms

UART is an asynchronous full-duplex serial communication protocol consisting of two data lines, Tx and Rx. Since there is no reference clock signal, both parties in communication must agree on serial baud rate, data bit width, parity bit, stop bit, and other configuration parameters to communicate at the same rate. Asynchronous communication transmits one character … Read more
