STemWIN How is this library doing today?

Luki · ‎2026-04-13

How is it with availability, are we updating what was once part of CubeMX? namely STemWin, i.e. the Segger enWIN version that was offered for free for the STM32 processor?

I didn't find anything about ST, except that it's not part of newer versions of CubeMX.

You can find STemWIN on Segger's website, but they're basically just trying to sell emWIN at a discount.

Alternatively, where can I download the latest version of this library?

Thank you for the information.

I think it's obsolete - replaced by TouchGFX ?

See: did the future version of STM32CubeMX support STemWin? - Feb 2020

And: Stemwin update plan - Aug 2022

Segger still have the general emWin product:

Still listed as a Partner product, but "Licence Type: Commercial with free trial version" - no longer free:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hello @Luki.

ST discontinued STemWin a few years ago. This means it is no longer free for new projects, and it has not been included in STM32CubeMX for quite some time.

That said, emWin is still an active GUI library, and SEGGER remains a valued ST partner. They continue to invest in supporting selected new STM32 devices.

ST’s investment in GUI software is focused on TouchGFX, which brings better UI performance, ease of use, and technical support benefits for STM32 users. In parallel, ST is also partnering with alternative GUI software providers such as SEGGER.

Best regards,
Johan
