STMICROELECTRONICS N.V. By allowing playback of Motion-JPEG (MJPEG) video files, TouchGFX brings extra pizzazz to small devices like home-automation products, wearables, medical devices, and industrial sensors, allowing rich features such as instructional guides or entertaining startup and pause screens to enhance the user interface. Developers can use their own MJPEG files or choose from the sample movies provided. A new video widget in TouchGFX Designer, with properties including start, stop, repeat, and go-to-frame, simplifies prototyping and is added to the application by drag and drop.
TouchGFX 4.18allows video decoding in either software or hardware. Hardware decoding is possible with STM32 MCUs that contain a suitable decoding peripheral, such as theSTM32F769andSTM32H7B3. Software decoding is available on all series devices except the STM32G0 series. Various strategies for video buffering, including direct rendering to the frame buffer and double buffering, help optimize memory demand and performance.
Additional new features ofTouchGFX 4.18include enhanced support for collaborative working, using XML to store text data and translations. XML simplifies sharing and merging various elements of the project as multiple team members contribute. The powerful and convenient features of previous TouchGFX versions are retained, including the partial frame buffer for very low RAM use, ultra-efficient rendering that prevents tearing effects, and support for low-cost non-memory-mapped SPI Flash.
For an easy start to GUI development projects,TouchGFX 4.18comes with examples showing how to use the new video capabilities and the necessary TouchGFX Board Setup (TBS) for the popular STM32 Discovery boards.
ST has also updated and extended the selection of display shields that help developers quickly get their user-interface projects running. The updated X-NUCLEO-GFX01M2 for Nucleo 64 boards has a 2.2" QVGA serial interface display and now supports theNUCLEO-WB55RG, making it easy to add a display to a Bluetooth® application. A newX-NUCLEO-GFX02Z1for Nucleo 144 has a high-speed parallel interface and QSPI Flash memory on-board, supporting among others theNUCLEO-U575ZI-QBoth are supported in TouchGFX 4.18.
TouchGFX 4.18is available now, free of charge, from st.com. The newX-NUCLEO-GFX02Z1Nucleo 144 Display Shield is also available now, at a retail price of $35.00. The X-NUCLEO- GFX01M2 will be available in December, also at $35.00.
