Following the previous article, Verilog *1* SPI – Development, we have simulated the design, but we have yet to see how it looks on the actual circuit. Without hands-on experience, it remains theoretical; simulation is merely a tool to expedite the actual circuit development, and we must not lose sight of that. First, let’s take … Read more
Someone is usingthe STM32H563 development productand has enabledDMA mode forSPI communication. They discovered an issue where, when theSPI data width is configured to16 bits or32 bits, using theSTM32 HAL library’sSPI DMA API start function results in no data transmission. However, if theSPI data width is configured to8 bits, the transmission works normally. What could be … Read more
In the SPI tolerance settings, different volume and area tolerances are established for various component types (such as R/C, IC, BGA, Chip, etc.), primarily based on the following core principles: 1. Component Structure and Soldering Characteristics ● R/C Components (Resistors/Capacitors): ○ Simple structure, small pad size, high precision requirement for solder volume. ○ Volume tolerance … Read more

Word count: 8843, reading time approximately 45 minutes A Comprehensive Comparison of UART and SPI in Embedded Systems UART and SPI are key communication methods in the electronics field. UART is suitable for simple long-distance connections, while SPI excels in fast data transmission. They are used in GPS modules, SD cards, and microcontrollers, and understanding … Read more
Editor SPI (Serial Peripheral Interface) is a high-speed full-duplex synchronous serial communication interface developed by Motorola, widely used for communication between microcontrollers and various peripherals (such as Flash, sensors, ADCs, etc.). This article will introduce the working principle of SPI and demonstrate how to use the SPI interface through practical code examples from the STM32 … Read more
Silence is golden, but it will eventually shine. Hello everyone, I am Silent. As a Java developer, have you ever encountered this dilemma: as the project grows larger and features keep piling up, you find that the core code’s coupling degree is increasing, and replacing a certain component requires significant changes, even a complete refactor? … Read more
1. What is QSPI? The SPI protocol actually includes three types of protocol interfaces: Standard SPI, Dual SPI, and Queued SPI, corresponding to 3-wire, 4-wire, and 6-wire configurations respectively. (1) Typically, when we refer to SPI, we mean Standard SPI, which has 4 signal lines: CLK, CS, MOSI, and MISO. The data line operates in … Read more
