STM32 Embedded graphic solution targeting battery driven applications with square and round displays resolutions up to 450x450

Solution Description

This Graphical User Interface (GUI) solution enables developers to easily add a smartphone-like GUI to your battery driven devices, ensuring a long battery life. 

You can now deliver a superior user experience while taking the full advantage of STM32 Ultra Low Power (ULP) family microcontrollers STM32L4 (Link). STM32L4 ULP family offer you advanced graphical features link 2D-DMA ChromART, CRG optimized for round display and MIPI display interface. 

The TouchGFX software engine utilize all graphical features of the STM32L4 micro creating a high performant application with a smartphone look and feel. The TouchGFX package supports you with a smooth development process....   

The full STM32 Graphical User interface offer is structured around the following pillars:

  • Industry’s broadest advanced graphic enabled MCU offer
  • State-of-the-art graphical development tools available for free
  • Support and documentation center
  • Reference designs and selected design partners
