Pros and Cons of Visual Studio Code

Intuitive and Highly Customizable Interface  

  • Visual Studio Code (VS Code) offers an intuitive user interface that is easy to navigate, making it accessible even for beginners. It provides extensive customization options including themes, keyboard shortcuts, and workspace settings which outperform many other lightweight editors, allowing engineers to tailor their experience to individual preferences.

Rich Ecosystem of Extensions  

  • VS Code boasts a robust marketplace with thousands of extensions that expand its functionality—such as code linters, debuggers, and connectors with other services. This vast ecosystem outshines many comparable tools in offering specific features needed by firmware engineers, such as device integration and platform-specific compilers.

Effective Integration with Source Control  

  • It seamlessly integrates with Git and other version control systems. The built-in tools for staging, committing, and branching allow firmware engineers to manage code versions with ease, providing a smoother experience compared to some other text editors that require additional setup for streamlined Git operations.

Resource Intensive for Extended Use  

  • VS Code, while lightweight compared to full-fledged integrated development environments (IDEs), can become resource-intensive, especially when multiple extensions or large projects are used. This can be a disadvantage compared to simpler editors like Sublime Text, which generally consumes fewer system resources.

Lacks Built-in Advanced Debugger Tools  

  • By default, VS Code does not come with advanced debugger tools frequently required by firmware engineers, such as those available in more dedicated IDEs like Eclipse. While extensions are available, they often do not match the depth and integration of tools found inherently in more specialized software.

Complex Setup for Some Embedded Development Tasks  

  • Setting up a complete and efficient embedded development environment with VS Code can be complex and time-consuming, as it often requires multiple plugins and configuration tweaks. Compared to dedicated embedded development IDEs such as Keil or IAR, which offer comprehensive solutions right out of the box, VS Code requires more customization effort to achieve similar results.
