examples for X-NUCLEO-GFX01M1

[dsamm]

we've just purchased a couple of  X-NUCLEO-GFX01M1 kits and want to test them with different nucleo boards.

The X-NUCLEO board should be compatible with the following: NUCLEO-F030R8, NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC, NUCLEO-F401RE, NUCLEO-F410RB, NUCLEO-F411RE, NUCLEO-F446RE, NUCLEO-G071RB, NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L412RB-P, NUCLEO-L433RC-P, NUCLEO-L452RE, NUCLEO-L452RE-P and NUCLEO-L476RG.

what is the best (and quickest) way to evaluate/test the display with L4 and F4 boards?

From TouchGFX Designer there is only one choice of template available working with the STM32G0 MCUs

I'm in the same situation. Also, I can't find the manual for the card (UM2750). When will it be ready?

That's the same for me! I'm interesting to develop something with STM32 other than the "default one" they provide as a starting demo

It seems no one is taking care of that. Maybe on YouTube we can find something?

Touch gfx from v4.15 as a template for the xnucleo gfx board.

But where are the three demo highlighted by the teaser video :?https://youtu.be/4DSb1-yuf2c

this demo Is very impressive for a SPI screen.

thx

Yes, I know the video in the link you post. impressive!

The point is that I'm dealing with touchgfx by starting from a template (in my case for the STM32F746-Discovery).

Even if I'm using a template, I spent some days on YouTube to find the "adjstument" needed for running the board with proper operation of the touch screen (why that ?? Why it doesnt work buy itself without "manual" adjustment?)

But I don't want to go OT with the '746

Yes there is the template for the XNUCLEO GFX expansion board, but it refers to coupling the expansion with the STM32G071-NUCLEO or in other words the template is for the '32G017 cpu.

Is it easy to migrate form the STM32G0 to another member of the STM32 family?

I've no idea, since I never try a project starting from scratch.

Hi Enzo,

Unfortunately I’ve no experience with Touch GFX. I’ve planned to acquire some and for this purpose I’ve build kind of STM32G071-NUCLEO and XNUCLEO GFX clone in order to start with a working environment and port it to other custom board with various CPU and SPI screen. That’s part of end of year vacation planning !.

To answer your question, yes it’s no so difficult to port a CubeMX HAL based software between STM32 families. Generate a project for G071- Xnucleo GFX with Touch GFX, this will be your source then generate with CubeMX a target project for your 32F746-Discovery with the same configuration (ports, names, peripheral) than the source one : open the .ioc file in source project and clone the configuration in the target, don’t forget to add ‘touchGFX’ Software pack and also ’XCUBE display extension board’ software pack. Generate the code a start porting ...

If you already made some YouTube search you should know those :

• integration tuto : https://www.youtube.com/watch?v=9QDWti5RzBU
• A whole course playlist : https://youtube.com/playlist?list=PLnMKNibPkDnEeRXg7w6DLVDfrovQJ3KAI
• A playlist with many tech video related to touch GFX integration : https://youtube.com/playlist?list=PLnMKNibPkDnGCh1M8IOCjtnJHbg9UNiMW

The configuration of the G071 board that should be replicated of the F746 is (this is a cubeMX report) :

Dear Chris,

Thanks for you reply and Happy New Year!

I appreciated a lot your suggestions. I will try to put them in practice soon.

I'm still engaged in another project.

Keep in touch!

Regards

Enzo
