Additionally, modifying container impacts every screen using it, which vastly simplifies developments. They enable programmers to reuse a set of widgets across multiple screens without having to reconfigure them every time. Containers are often the building blocks of an interface. To make widgets more straightforward, designers can group them inside a container. The software comes with many predefined widgets, such as a gauge, clock, or graph, and developers can design their custom widgets. In its most simplistic form, TouchGFX Designer relies on widgets, a representation of a feature drawn on the screen. There are also existing default setups for the ST development boards to hasten developments and serve as examples. Indeed, Generator creates empty functions to guide developers and facilitate board initialization. Developers still have to fill some blanks with their user code and perform optimizations, but this new plugin makes starting a project a lot more straightforward. TouchGFX Generator works with STM32CubeMX to generate a significant portion of the TouchGFX abstraction layer. We support nearly all STM32 Discovery Kits with a display, and the new plugin works with any STM32 MCU with a Cortex-M0+, M4, or M7. TouchGFX Generator TouchGFX Generator and Designer working together on a smartwatch As a result, developers can check if their animations waste MCU resources by unnecessarily invalidating assets. Similarly, pressing F2 highlights invalidated areas, meaning the sections of the frame that the system must update. For instance, it is easier to take various screenshots and study animations frame by frame. Part of its appeal is that it offers keyboard shortcuts to streamline workflows. TouchGFX Simulator helps developers preview their graphical user interface before running it onto their MCU. The system will automatically update TouchGFX Designer without needing to close the application. Similarly, a developer can start with TouchGFX Generator, move to TouchGFX Designer, and then go back to STM32CubeMX to change the display resolution. IOC file to apply the new settings immediately. TouchGFX Designer is an integral part of the TouchGFX ecosystem. For instance, as long as users choose a 3.0 template, it is possible to start the project in Designer, then take it to STM32CubeMX, set up the Discovery board or MCU, and let TouchGFX Generator (see below) update the. UI elements in TouchGFX Designer often take the form of widgets one adds and configures through the utility’s interface. Hence, running example codes and demos takes minutes, which means creating proofs-of-concept faster. A startup screen helps choose the demo application, an ST development board, and then configures everything. There are also more full-fledged demos like dice animation, scene transitions, or a pool monitoring system. Developers can start with example projects, such as a clock, gauge, or animated image. It’s a utility with a WYSIWYG approach where designers create what their users will see and interact with. TouchGFX Designer is often the first tool developers use when starting their UI. TouchGFX Designer creating a UI for a coffee machine To help them in the process, TouchGFX Documentation provides information on the framework’s APIs or available development tools. Additionally, the ability to access the code generated allows expert engineers to optimize it. It is also extensive as it handles 2D and 3D objects, videos, animations, transitions, etc. Hence, the framework is intuitive and reflects one’s experiences. TouchGFX works under the assumption that interfaces consist of screens users navigate. TouchGFX is ST’s free-to-use framework that helps create graphical user interfaces on STM32 microcontrollers. Written in C++, the engine takes advantage of optimizations on ST devices.
