19 "Ten Thousand Miles" Raspberry Pi Car——VSCode Learning (Multiple C File Link Debugging) [Copy link]

 

In the past, when programming embedded systems, you didn’t need to worry about compiling and linking when using Keil or IAR, because the IDE was ready. Writing multiple C files on Linux requires compiling them separately, or writing Makefile files, which greatly reduces development efficiency.

Earlier we introduced debugging with VSCode. In fact, as long as you add the files that need to be linked in the generated tasks.json, you can perform multi-file link compilation and debugging.

Procedure

First, open VSCode, clear the workspace of the existing project, click "Open File", select the folder where the driver routine is located, and refer to the previous VSCode debugging post to build the debugging project.

Then, based on the originally generated tasks.json file, add the wiringPi link library and three other cpp file commands, as shown in the red box below.

Operation effect

Press F5 to debug (do not press the run arrow in the upper right corner).

Through simple settings, the compilation, linking and debugging of multiple C files can be achieved. Sharpening the knife does not delay the chopping of wood, and subsequent development work will be more convenient and quick.

question

In VSCode, you can use CMake to compile and link multiple C files. What is this? Is it necessary to learn it?

Is it difficult to achieve these? How long does it take to get started? Thank you!

I don't quite understand what you mean by implementation. If you want to talk about getting started, I'm not even getting started yet. I've never been exposed to Linux before, and I don't have anyone to guide me. I'm just groping on my own, stumbling along the way, and I don't know when I'll be able to get started, but I'm just enjoying it.

If the project is not large and only has a few files, there is no need to use cmake. If the project is large, the compilation speed will affect the development efficiency, and you have to consider the makefile issue.

The easiest way is to install VS on your computer and connect to your Raspberry Pi remotely.
