Apart from the official libraries part of STM32Cube, are there libraries compatible with the STM32duino SDK to use with the STM32F746G Discovery screen?
Thank you!

Hi
@Velero
I've made a test 1 or 2 years ago.
I've rebased it to the 1.8.0.
You can test it using this branch:
https://github.com/fpistm/Arduino_Core_ ... TEST_1.8.0
Discplay and touchscreen are functional.

Hi,
Can I use this in a PlatformIo arduino (I guess stm32duino) stm32f746-Discovery (disco_f746ng) project? If yes, how?
If not, can you recommend a suitable TFT/Touch library for stm32f746-disco to use in a pio arduino project.
Thanks in advance.

Well you will have to add it manually.

Hi
@ta1db and
@Velero
I've rebase the branch on top of 1.9.0 release and tested:

Hello @fpiSTM,
Is it possible to have this part of the upcoming 2.0.0 release?

I don't think it is only for example and not enough generic.

If not part of core release, is it possible to release just the libraries, LTDC and TS?
It will be interesting to have it managed directly by the IDE, as the others STM32DUINO libraries.

Same, I will not do this as it will require support and not enough generic and not enough time for this. You can do it on your own.

The libraries are working.
But, if touch doesn't work check the C Runtime Library you are using.
- With Newlib Standard, it blocks in TwoWire::allocateTxBuffer, realloc gives null result and we go directly in ErrorHandler.
- With Newlib Nano, everything works well, realloc allocates the buffer.
Don't know why I used Standard for this project. I usually use Nano.
