👉STM32CubeIDE Tutorial Collection Recently, my company received a lawyer’s letter from MDK, leaving us no choice but to use open-source or free IDE tools. Considering various factors, I ultimately decided to use the STM32CubeIDE provided by STMicroelectronics. I found that there are relatively few tutorials on CubeIDE available online, which inspired me to create a … Read more
1. Memory Mapping In the memory mapping diagram of the STM32F429 chip, it can be seen that the peripherals are allocated 512M of space; however, the actual peripherals do not utilize the entire 512M of memory. When operating peripherals, it is sufficient to manipulate their corresponding memory addresses. For more detailed peripheral memory addresses, refer … Read more
STM32CubeIDE integrates the STM32CubeMX graphical configuration tool and a powerful code generation engine, allowing developers to automatically generate initialization code through intuitive pin dragging and peripheral selection, significantly reducing low-level configuration time. Whether it’s GPIO, timers, UART, or ADC, everything can be configured with a single click. Coupled with the HAL library‘s standardized API, even … Read more

SPI Physical Layer SPI generally uses 4 lines for communication: NSS: Chip select line MOSI: Master data output, slave data input MISO: Master data input, slave data output SCK: Clock line, provided by the master 2. Protocol Layer (1) Basic SPI Communication Timing (2) … Read more
Click the blue text Follow us 1. Introduction to I2C The I2C communication protocol (Inter-Integrated Circuit) was developed by Philips. Due to its fewer pins, simple hardware implementation, and strong scalability, it does not require external transceivers for communication protocols like USART or CAN, and is now widely used for communication between multiple integrated circuits … Read more
STM32CubeIDE is an integrated development environment officially launched by ST, which integrates code writing, compilation, debugging, and downloading functions, and includes the graphical configuration tool STM32CubeMX. It supports the HAL library and provides a complete solution from hardware configuration to firmware development, making it especially suitable for beginners and rapid prototyping.The combination of Keil and … Read more
This article is reprinted from the Jishu Community Author: Once a Job’s Tears Introduction Recently, I had the privilege of experiencing the Lingdong Micro MM32F5265 development board. The MM32F5260 is equipped with the Arm China “Star-MC1 core” processor, which offers high performance and is aimed at high-reliability application fields such as home appliances and industrial … Read more
01 Introduction In the development of embedded systems based on STM32 microcontrollers, GPIO (General Purpose Input/Output) control is one of the most fundamental and common operations. By using the STM32 HAL library, configuring and controlling GPIO can be done easily. This article will demonstrate how to use the STM32 HAL library for GPIO control and … Read more
Reminder: This article provides a detailed analysis of the functions related to GPIO configuration in the HAL library, including MX_GPIO_Init(), HAL_GPIO_WritePin(), and HAL_GPIO_Init(). At the end of the article, a description of the f1 series GPIO port registers is attached. MX_GPIO_Init() First, let’s look at the source code: void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct = {0}; /* … Read more
Introduction In serial communication applications, we often use receive and transmit interrupts, which most of you are familiar with. There is a very useful interrupt that may be overlooked, which is the bus IDLE interrupt. When a frame of data transmission ends, the bus will maintain a high level state, at which point the MCU’s … Read more
