Geneva. STMicroelectronics ratified its TouchGFX software package for simpler user interface (UI) designs that work collaboratively with STM32 microcontrollers. The 4.21 runs through the NeoChrom GPU processor, and utilizes TouchGFX Stock to control graphics for end-products.

The updated 4.21 features a new widget in the TouchGFX Designer tool to support Scalable Vector Graphics image format (SVG).  

The package contains the TouchGFX Designer with 50+ developments that are ideal for home appliances, building automation controls, industrial machinery, fitness trackers and other wearables, and medical devices.
