The SPI (Serial Peripheral Interface) is one of the most widely used synchronous serial communication protocols in embedded systems, playing a crucial role in STM32 development. Compared to I2C and UART, SPI is particularly suitable for high-speed data acquisition, memory expansion, and display driving due to its full-duplex communication, high transmission rates, and hardware slave … Read more
Implementing the SPI (Serial Peripheral Interface) driver on the STM32 microcontroller for communication with sensors. The content includes SPI initialization, data transmission, error handling, debugging techniques, and the use of logic analyzers. The code is based on the STM32Cube HAL library, suitable for the STM32F4 series (such as STM32F407), and uses a generic sensor (like … Read more

Hello everyone, welcome to<span>LiXin Embedded</span>. In embedded development, whether it is sensors, memory chips, or GPIO expansion modules, the presence of I2C can be seen everywhere. In this article, we will start from the basic working principles of I2C and delve into common issues and their debugging methods. Why Choose I2C The I2C bus is … Read more
Why is I2C so important? In modern electronic devices, communication between chips is ubiquitous. For example, your device has dozens of sensors and chips that need to “talk” to each other—the accelerometer needs to inform the processor of the device’s motion state, the touchscreen needs to relay user click information, and the camera needs to … Read more
