3Development environment

3.1 Demonstration software

The demonstration software supporting the X-NUCLEO-GFX01M1 and X-NUCLEO-GFX01M2 expansion boards

is available from the X-CUBE-DISPLAY STM32Cube Expansion Package and must be programmed into

the corresponding Nucleo board. The latest versions of the demonstration source code and associated

documentation can be downloaded from www.st.com.

4Quick start

Before the first use, make sure that no damage occurred to the board during shipment:

• All socketed components must be firmly secured in their sockets

• Nothing must be loose in the board plastic bag or in the box

To start using the X-NUCLEO-GFX01M1 or X-NUCLEO-GFX01M2 expansion board, follow the steps below:

1. Plug the board on a compatible STM32 Nucleo development board

2. Download the evaluation firmware and full set of documentation from www.st.com/en/product/x-cube-display

and program the target device

3. Evaluate the graphic possibilities of STM32 devices combined with the TouchGFX Engine graphic library in

X-CUBE-TOUCHGFX or develop your own application
