Hello all

Do we knoiw for the example like ( https://support.touchgfx.com/docs/development/scenarios/running-graphics-from-external-ram ) but for the STM32H750B-DK board where the bigger LCD is used?

Any comments are more than welcome!

Hello @total_and_STM32.

Could you please elaborate on what your question is?

If you are looking for examples on how to integrate a larger display with the STM32H750B-DK, I would recommend you to first of all have a look at the TouchGFX Board Setup (TBS) available in TouchGFX Designer for the STM32H750B-DK. Assuming the larger display also uses a parallel RGB interface, it should be fairly straightforward to configure it by modifying the LTDC settings in STM32CubeMX.

Best regards,
Johan

Thanks for your reply,

It looks very promising, thank you again!

For fun, have a look at what I am going through https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/touch-gfx-and-custom-lcd/td-p/861733 since this information was not known to me :) need to review  the actual TouchGFX Board setup as described here https://support.touchgfx.com/docs/development/scenarios/scenarios-create-at 

This information should pop up the first thing when someone opens the Touch GFX documentation :)

Anyway, thanks!!! Fingers crossed, this will help me set up

I do not think you can use that documentation link in your current state. The procedure described there is for later, when your board setup is running and you want to e.g. distribute it or base multiple GUI projects on the same hardware setup.

What I am referring to are the TBSs that are available in TouchGFX Designer under the "Create" tab.

These are complete TouchGFX board setups for some of the graphics-relevant evaluation boards. They are open source and can be used as a reference when developing board setups for custom hardware.

Best regards,

OK! Thanks!

So, when "the project" is created in the TouchGFX designer for the STM32H750b-dk, how can it then be opened in the CUBE IDE, or CUBE MX, where the LTDC is set up for the custom LCD?

Is this the idea, or is the resolution, etc. of the display defined within the TouchGFX Designer?

So far, I cannot define the dimension nor the color depth while the display orientation can be determined, see below.
