A few days ago, a beginner asked me why, after running through all the examples on the STM32 development board—from lighting LEDs, handling buttons, serial communication to ADC acquisition—he felt he understood the code. However, when it came to starting a project, his mind went blank, and he had no idea where to begin. It … Read more
For embedded development beginners, the choice of the first development board directly determines the difficulty of getting started – choosing the right one can yield great results with minimal effort, while choosing the wrong one may lead to discouragement. This article compares five popular development boards: 51 Microcontroller, STM32, Raspberry Pi Pico, Raspberry Pi, and … Read more
Project Background: A “Random Crash” Bug Caused the Loss of Over 200 Chips, Exceeding 80,000 At that time, we were developing a motor control board based on STM32F407. After mass production and programming, we found that: Some boards were unresponsive after startup Some crashed after running for a while without restarting or output Some got … Read more
This article introduces the concept of tasks in the FreeRTOS operating system, including task creation, deletion, and task states.1. TaskFreeRTOS tasks are the core units for implementing concurrent execution of multiple tasks, essentially functions with independent execution environments.Each task is an infinite loop function (or a self-deleting function) that has its own stack space and … Read more

1.Hardware Introduction The photoresistor is a special resistor made from semiconductor materials such as sulfide or selenide, and its working principle is based on the internal photoelectric effect. As the light intensity increases, the resistance value rapidly decreases. The charge carriers generated by the light participate in conduction and drift under the influence of an … Read more
IntroductionIs debugging STM32 giving you a headache lately? UART printing is too slow and resource-consuming, and you have to set breakpoints just to check variables. Not to mention, tracking high-frequency signals is nearly impossible… Don’t worry, today I want to introduce you to a powerful tool—MCUViewer—that will completely liberate your debugging process. What is MCUViewer?MCUViewer … Read more

What is preemption? What is response priority? What is the purpose of priority grouping? Why does the priority you set not take effect at all?Don’t … Read more
Introduction: In early February or March, the author replicated a simple desktop pet – the STM32 desktop robotic dog based on online tutorials. Although it is a robotic dog, the author has finally found some free time to open source the relevant code and design. Interested readers can give it a try. Main Content: Hardware … Read more
