01SD Card SD Card is the abbreviation for Secure Digital Card, which translates directly to “secure digital card.” It is a proprietary non-volatile storage card format developed by the SD Association for portable devices. Due to its small size, fast data transfer speed, and hot-swappable features, it is widely used in portable devices. The standard … Read more
Buses, buses, they always get you tangled up. In this world, signals may be the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses are used for interconnections between peripheral chips and processors within … Read more
In the SMT (Surface Mount Technology) production line, the birth of each circuit board is a game of precision and efficiency. From solder paste printing to component placement, and then to soldering and curing, even the slightest flaw in any link can trigger a “butterfly effect”—leading to unstable product performance at best, or mass rework … Read more
Click the Blue Text Follow Us Introduction to SPI SPI (Serial Peripheral Interface) is a synchronous serial communication protocol used for data transmission between devices over short distances. It is commonly used for communication between microcontrollers and external devices such as sensors, flash memory, displays, etc. SPI has the following main characteristics: Basic Principles SPI … Read more
Hello everyone, I am XXX. Today I bring you a detailed analysis of microcontroller communication protocols, including mainstream protocols such as UART, I2C, and SPI. These protocols are the bridge for data exchange between microcontrollers and other devices, and mastering them is crucial for embedded system development. Let’s break them down one by one, and … Read more

Source: https://blog.csdn.net/an520 UART, SPI, and I2C are very common serial communication methods in embedded development. The underlying principles of these communications are not difficult, but many beginners struggle to learn them. Today, I will share some common low-level data transmission principles of communication. UART Serial Port UART: Universal Asynchronous Receiver-Transmitter. UART is the most common … Read more
Abstract: This paper proposes a design method and specific implementation plan for a control system based on dual STM32 chips. The control system uses two STM32F107VCT6 chips as master and slave controllers, communicating via a high-speed SPI interface to ensure real-time performance during the control phase. The hardware layout of the system is introduced, and … Read more
