When starting to learn about embedded systems or microcontroller systems, most people’s learning method is to find video tutorials or books to learn by themselves. Some may spend money to enroll in a training class to learn with a teacher. When you slowly become capable of writing code independently, you might feel like you have … Read more
This article mainly shares an open-source management module that helps achieve layered management of applications and hardware in an MCU project. Nowadays, project requirements are more complex, which naturally imposes stricter demands than before. From a technical perspective, I still recommend that everyone should maintain a layered structure (application and driver) in their projects. This … Read more
This Session’s Learning Implementing Two Lines of Different Content on LCD Using Code Knowledge Points for This Session: Understand how to achieve a two-line display effect on the LCD (the last learning session of microcontrollers this semester) Learning Tools: Computer, Keil uVision4 software, Proteus software Microcontroller Explanation After several weeks of studying microcontrollers, I believe … Read more
Introduction Microcontrollers are quite “low-level” and “hardware” components, lacking complex data structures and intricate programming algorithms. We only need to understand and program from the perspective of how the microcontroller executes. For the average person, there is no need to delve deeply into the subject, as most of us are merely users of microcontrollers, not … 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
Introduction The STM32 series chips are developed based on the Cortex-M3 core. They adopt the industry-leading Cortex-M3 core architecture, utilizing Harvard architecture and the Thumb-2 instruction set. They can achieve 32-bit performance with a 16-bit code density. Additionally, with single-cycle multiplication instructions, hardware division instructions, and a built-in fast interrupt controller, STM32 chips can run … Read more
● General Timer (TM2~TM5) The general timer is managed by the chip and can perform up counting, down counting, or both simultaneously. Additionally, these timers have other functionalities: input capture, output compare, PWM, and single pulse. ● From Manual to Flow The main module of the timer consists of a 16/32-bit counter and its related … 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
Have you ever wondered why software can control hardware? This article analyzes how the STM32 microcontroller combines software and hardware and how the microcontroller program is compiled and executed. Software and Hardware Integration Beginners often have a question: why can software control hardware? Just like the 51 microcontroller, why can we output high and low … Read more
