2.5D Accelerator with massive hardware optimizations for rich UIs on STM32, fully integrated in X-CUBE-TOUCHGFX. Learn more.


TouchGFX is an advanced, free-of-charge GUI optimized for STM32 microcontrollers. Taking advantage of the STM32 graphical hardware acceleration, architecture, and ecosystem, TouchGFX accelerates the HMI-of-Things revolution through the creation of stunning smartphone user interfaces on embedded devices ranging from simple low-color UI applications up to high-resolution and high-color UI applications.

TouchGFX is optimized for STM32 microcontrollers, needing only a limited amount of memory for running smooth GUIs.

The TouchGFX solution is distributed as an STM32Cube Expansion Package (X-CUBE-TOUCHGFX), which includes all TouchGFX software to hep users develop their UI application. TouchGFX interoperability within the STM32 ecosystem provides users with an easier and faster development process.
