In C++ development, debugging is an indispensable part of the process. Whether it is finding logical errors in the program or detecting memory leaks, the right debugging tools can significantly enhance our work efficiency. This article will introduce two commonly used C++ debugging tools: GDB and Valgrind, and provide detailed usage methods and code examples. … 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
Application Overview Hello everyone, I am Bao Ge! Today I bring you a super friendly communication upgrade tutorial for the S7-1200 PLC. As an experienced PLC user, I know that many friends encounter communication issues when first dealing with Siemens PLCs.This S7-1200 is, in my opinion, the most suitable PLC for beginners; it is not … Read more
Overview 1.1 What is the SWD Protocol SWD (Serial Wire Debug) is a two-wire debugging interface protocol developed by ARM, specifically designed for debugging and programming Cortex-M series microcontrollers. As a replacement for the traditional JTAG interface, SWD significantly reduces the number of pins while maintaining powerful debugging capabilities, making it the mainstream choice for … Read more
When programming in C++ under the Linux environment, multithreading provides excellent concurrency capabilities, allowing programs to perform more efficiently when handling complex tasks. However, multithreaded programming is not without its challenges; deadlock issues lurk like hidden “killers,” potentially causing programs to become stuck. Once a deadlock occurs, the program is trapped in an unbreakable loop, … Read more
On the long road of software development, bugs are like “little monsters” hiding in the dark, occasionally jumping out to cause trouble for developers. Once, the European Space Agency (ESA) launched the Ariane 5 rocket for the first time, which was an important moment in the history of space exploration, but a single line of … Read more
⬆ Follow “Python-Wu Liu Qi” to learn easily together～ After reading this article, your code debugging skills will improve 🌈Hey, friends! Today, let’s talk about those annoying error messages in Python programming. Writing code and encountering errors is a common occurrence. When faced with a pile of English error messages, how can you quickly identify … Read more
In the previous article, it was mentioned that in assembly, the content of registers is modified through assembly instructions to control the CPU’s operation. Several classifications of registers were also discussed.Understanding the concepts can be a bit dry, so today we will look at several registers through debugging on a PC, and also modify the … Read more
Scan the code to follow Chip Dynamics and say goodbye to “chip” blockage! Search WeChatChip Dynamics The C language does not have a true string type; instead, it uses a character array + ‘\0’ (null character) to represent a string. Thus, <string.h> provides a group of “text wizards” (string functions) to help us manipulate these … Read more
