New Electronics – ST releases TouchGFX 4.20 for advanced graphics on STM32 microcontrollers

STMicroelectronics has released version 4.20 of its TouchGFX user interface design software for STM32 microcontrollers.

The latest update includes support for ST’s new NeoChrom graphics accelerator, which is built into advanced microcontrollers such as the STM32U5 series.

Developed from ST’s Chrom-ART accelerator that manipulates pixels and shapes, NeoChrom allows full-screen rotation at any angle and supports texture mapping for smooth graphics and ease of use. improved.

With the on-chip NeoChrom accelerator, the latest STM32 microcontrollers are expected to elevate on-board graphics performance to the level of application processors used in modern smartphones and tablets. However, they are also more affordable, energy efficient and easier to use, according to ST. They can run on simple operating systems such as FreeRTOS and Microsoft Azure ThreadX, or even bare metal.

“TouchGFX 4.20 now enables developers around the world to unleash NeoChrom-accelerated graphics in embedded systems containing our latest and most power-efficient STM32 microcontrollers,” said Ricardo de-sa-Earp, Executive Vice President, subgroup of general purpose microcontrollers, microcontrollers and digital. CI Group, STMicroelectronics.

TouchGFX 4.20 added a number of new features for developers, including support for importing and exporting custom widgets. The environment includes TouchGFXDesigner, the graphical development tool, and the embedded software X-CUBE-TOUCHGFX, which provides all the firmware needed to run the user interface on the target MCU.

Fully integrated with the STM32Cube MCU development ecosystem, TouchGFX provides a complete end-to-end workflow that simplifies design and speeds time to market.

TouchGFX 4.20 is available now, free of charge, and can be downloaded directly from ST’s website.
