Five Considerations for Microcontroller Embedded Programming

Five Considerations for Microcontroller Embedded Programming

In the process of microcontroller programming, if a designer can master multiple programming languages simultaneously, then that designer is undoubtedly a very talented individual. However, mastering assembly, C, and C++ at the same time is quite challenging, and many beginners struggle significantly while learning just one of these languages. This article specifically compiles opinions from … Read more

In-Depth Analysis of Zephyr Code Relocation Technology: From Principles to Best Practices

In-Depth Analysis of Zephyr Code Relocation Technology: From Principles to Best Practices

In modern embedded system development, code relocation technology is becoming a key means to optimize system performance. Imagine a scenario where your real-time control system experiences a 30% delay in critical interrupt response due to Flash access latency, or is unable to add new functional modules due to Flash capacity limitations. These are the pain … Read more

Introduction to Assembly Language: Using Debug Tools

Introduction to Assembly Language: Using Debug Tools

1. Physical Memory Layout Formula When you see an address like 0B3F:0100 in debug, remember the physical address calculation formula: For example, 0B3F*10h+0100=0C3F0. This formula explains why CS:IP always points to strange memory locations (a legacy black magic of old programmers). 2. Core Command Anatomy Command Prototype: -a [address]Parameter Description: If address is not filled, … Read more
