Everything you learn will be of great value for years and likely decades to come.

They are, and will remain, free software (open source), with decades of tradition, and no big surprises in sight. OTOH, if you do want to get serious, then I really suggest you invest some time, learn about the backend tool structure, and get the bare tools separately, and learn to use them directly.

Just don't take these tools too seriously, install something and see if it works. The idea is, you get something running quickly, then concentrate on the actual code. This being said, they don't require that much time, typically. So there is confusion, and all time you spend on these tools will be lost, you learn nothing. Then it got discontinued without a warning, and you needed something else which I forgot already, now you need Atollic TrueStudio, soon it will be something else again. Just a few years ago, you were not trendy if you didn't use CooCox. But you need to know the latest one in order to be the cool kid. They change names, ownerships, get discontinued, and everybody forgets about them. The "trend IDE of the year" pulls the carpet below your feet, well, every year. I understand your confusion trying to Google this matter. You'll also want to look into using STM32CubeMX, which is included within STM32CubeIDE, but can be installed separately. Perhaps try logging in before clicking the download button? I dislike all the website changes they've been making for the last year, and I figure they are breaking things.

I was able to download STM32CubeIDE last week. I think that TrueStudio and STM32CubeIDE are both partially closed-source, so use System Workbench if you want a fully open-source IDE. One note is that STM32CubeIDE does not have the capability to debug RTOS threads/objects whereas TrueStudio does. All three of these products are Eclipse-based and I've had an easy time going between them. A month or two ago, STM released STM32CubeIDE and announced that TrueStudio will no longer be released.


I've not used System Workbench in the last few years since switching to TrueStudio, but some of my students used it since it works on MacOS X whereas Atollic TrueStudio is Windows & Linux only. A few years ago, STM purchased Atollic, and made its TrueStudio product free. System workbench used to be the best-supported (only?) free IDE.
