The design trends in embedded HMI (Human-Machine Interface) are continuously evolving. With products getting smarter and offering an increasing number of features, end users expect HMIs to provide an engaging experience and easy access to product features.

Including a GUI (Graphical User Interface) in your products will allow you to design a more user-friendly, safe, and modern device, offering end users more value. The key design requirements of GUIs are shaped by the one device we all interact with every day: the smartphone in our pockets.

Ready to get started?

The STM32 family provides the tools required to easily add smartphone-like Graphical User Interfaces (GUIs) in embedded devices, accelerating the "HMI of Things" revolution.

Graphics on STM32 MCUs

Use GUIs to offer the best UX

To design embedded products offering an outstanding user experience, the STM32 family offers the industry’s broadest range of graphics-enabled MCUs with over 200 active part numbers, supporting different display interfaces and packaging options. The STM32 graphics enabled MCUs embed different features that allow developers to achieve the desired performance and optimization trade-offs required for embedded devices, such as:

  • The Chrom-ART Accelerator™ offers memory-efficient 2D graphics acceleration and enables smooth transitions and transparency effects while offloading the main CPU
  • NeoChrom GPU, New 2.5D Accelerator With Massive Hardware Optimizations for Rich UIs on STM32. The technology optimizes animations such as flips, spins, scaling, zooms, and more. In a nutshell, the new hardware IP accelerates texture mapping and alpha blending. Offloading these computations to NeoChrom GPU vastly increases the number of frames per second.
  • NeoChrom VG GPU is the first vector graphics accelerator specifically designed for vector graphics computations. It builds upon the technology of the NeoChrom GPU.
  • The JPEG codec allows you to add M-JPEG videos for branding and tutorials
  • Fast access to internal and external memory avoids bottlenecks, supporting smooth animations
  • The large internal memory supports a one-chip solution, without requiring an external RAM and Flash for small-resolution displays. This brings you additional flexibility to secure system architecture, your buffer strategy and memory budget
  • Support for large display interfaces with parallel interfaces, LCD-TFT, and MIPI-DSI embedded controllers

What it takes to develop a GUI

Creating a good GUI requires skills and expertise, and involves many building blocks, starting with the selection and sourcing of the right display and casing, the art-creation of menus and screens, the programming of the art-design into a user interface and the electronic development, before being able to connect the dots and to trigger the spark that will bring your design to life.

We know it can be overwhelming to develop a GUI.

That is the reason why ST provides state-of-the-art and MCUs, combined with the tools and the support you need every step of the way, to ensure you bring your GUI project to success.

Graphics on STM32 MPUs

The STM32 graphics offer is designed to help you create stunning graphical user interfaces (GUIs) on STM32 MPUs with ease. Building a GUI on an MPU requires optimization for memory usage, performance, input/output devices, power consumption, and user experience. ST recognizes these challenges and offers a range of graphics solutions, with ST Authorized partners' support, to help you create a GUI that is both visually appealing and optimized for performance. This comprehensive approach takes into account the unique constraints of embedded systems, ensuring your MPU-based GUI delivers a smooth and responsive user experience.

3D Graphics Processing Units (GPUs) offer the capability to handle complex 3D graphics calculations and rendering much faster than CPUs, while also being more power-efficient.
