How to add user source files to STM32CubeMX project?

I created a project with STM32CubeMX, generated the source code (for MDK-ARM5), then expanded my code by adding a couple of new source files.

Later, I went back to tweak my original Cube project and when I regenerated the source code, it deleted my new source files and created a new Keil project that didn't know about my new sources.

Is there a trick to doing what I want here? My workaround so far is to store my new code in a separate folder - but I still have to re-add them to my project if I ever re-generate the source code.

Thanks.

Hi seymour.jim,

First, be sure that you are using the last version of CubeMx (4.16.0 now)

For the option ''Keep user code when generating'' ( in â€œProject settingâ€� -> â€œCode generatorâ€�), it is checked by default but also you can verify it

.

Try to copy and paste the files that you want to add in source folder of your generated project -> add the files in workspace â€“> regenerate project.

Thanks. I am using the latest version and that option was selected.

But now I'm having trouble duplicating the original bug, so I'm not 100% sure about it anymore.

I still have to manually add my custom source files to the project when I do a regenerate, but the files themselves didn't get deleted the last couple of times I tried this.

Weird.

Hi seymour.jim,

So it's OK. It seems that the first time you were not adding the files to the generated project's repository.

I am fairly confident that I can reproduce the problem, so I don't think it's ''OK''. But it clearly does not happen all the time, so it's not the big, scary bug I thought it was.
