Introduction to ARM Bare-Metal Programming and Embedded Systems Getting Started with ARM Bare-Metal Programming: From Zero to Embedded Development Hello everyone, I’m Daodao. Today, let’s talk about ARM bare-metal development. Many beginners feel overwhelmed when they see ARM, thinking it’s particularly difficult. In fact, it’s not; once you grasp the essentials, writing a simple LED … Read more
Getting Started: Bare-Metal Programming on ARM Cortex-M Microcontrollers Bare-metal programming typically refers to the process of writing programs to control hardware devices directly without an operating system. For embedded system developers, this is a fundamental and important skill. Today, I will guide you through how to implement bare-metal programming on ARM Cortex-M series microcontrollers. Starting … Read more

This article introduces a precise delay method in the Cortex-M kernel. Introduction Why learn this delay method? Many times when we run an operating system, we generally occupy a hardware timer – SysTick, and the clock tick of our operating system is generally set to 100-1000HZ, which means an interrupt occurs every 1ms – 10ms. … Read more
Reply 1024, randomly give you beautiful wallpapers Debugging breakpoints tracking is an important means of analyzing code and solving bugs during software development. The use of debugging tools varies across different IDEs, but the debugging features provided are certainly comprehensive. Many programmers’ debugging abilities are limited to basic step execution and breakpoint jumping, unaware that … Read more
From time to time, friends ask: Where can I find good embedded projects? How can I improve my programming skills? Are there any practical projects to share? Today, I will take some time to organize some open source projects that I think are quite good, hoping to help everyone.

Select “GuaGua Little Master” at the top, choose “Pin/Star Public Account“ Useful content delivered promptly! Summary: For microcontroller programs, everyone is familiar, but not many truly consider the architecture. With the continuous increase in program development, architecture is very necessary. There are roughly three architectures for applications: 1. Simple front and back sequential execution program, … Read more
1. Basic Concepts In embedded operating systems, BootLoader runs before the operating system kernel and is the first piece of code executed after the system is powered on. It initializes hardware devices, establishes a memory space mapping, and configures the system’s software/hardware environment to an appropriate state to prepare the environment for the operating system … Read more
Selected from GitHub Author: Zoltan Baldaszti Compiled by: Machine Heart Editor: Chen Ping The Raspberry Pi, though small—only the size of a credit card—functions just like a regular computer, capable of connecting to TVs, monitors, keyboards, and mice. It can handle text, spreadsheets, media, and even games. So how can this magical little computer be … Read more
Robots have a long history. In ancient times, the Hebrews wrote an article called “The Living Automaton” to help with tedious labor; Da Vinci designed the “Mechanical Knight” in 1495; and Westinghouse’s Televox robot was created in 1927, allowing humans to send commands using voice. These achievements paved the way for the future vision of … Read more
