ST Launches X-NUCLEO-GFX01M1 Display Board
Available with various STM32 MCU development boards
TouchGFX 4.15 supports non-memory-mapped SPI flash


A solution has been released that allows developers to easily add displays to a variety of embedded devices. STMicroelectronics announced on the 19th that it has released the 'X-NUCLEO-GFX01M1' display expansion board for the STM32 NUCLEO board.

The new expansion board includes a 2.2-inch QVGA (320×240) SPI display, 64Mbit SPI NOR Flash, and a joystick, and can be used with various STM32 MCU development boards such as the NUCLEO-G071RB.

Developers can add a small display to any device for as little as $5 using the X-NUCLEO-GFX01M1, the STM32G0 MCU family, and TouchGFX software.

The latest 4.15.0 version of TouchGFX software reduces GUI RAM footprint by up to 90%, allowing simple GUIs to be implemented using only 16 to 20 KB of internal MCU RAM.

A new rendering algorithm optimizes partial screen updates in an optimized order, improving GUI performance and enabling additional updates while preventing visually distracting tearing effects.

It also supports non-memory-mapped SPI flash, allowing additional low-cost off-chip storage for memory-intensive graphics resources such as images and fonts.

Application templates optimized for the STM32G071 NUCLEO board and display kit provided by TouchGFX Designer This allows for easy implementation of GUI prototypes. If necessary, RTOS can be applied to the configuration, and the TouchGFX generator can be used to change to other hardware.
