TouchGFX- STM32F423ZHT6

Hi,

STM32CubeIDE- 1.13.2

TouchGFX -  4.24.0

STM32F423ZHT6 evaluation board has lack of LTDC and DMA2D compare to other STM32F4 series. I want to turn on the LCD panel (NHD-2.8-240320AF-CSXP-FCTP-ND) and it display the white background. Can any one please guide me? How to do it.

Hello @Marudhupandian ,

 

TouchGFX allows for a simple and quick control of a screen thanks to its framework but it is not plug and play for all boards.
For a few STM32F4 we have made a TBS (TouchGFX Board Setup) that allows those board to be plug and play but this is not available for the STM32F423HT6.
This means that you have to create your TBS yourself, basically giving TouchGFX the information about your board speed, communication protocol, screen technology, etc.

You can find how to make a TBS in our documentation : board-introduction 

Furthermore, you can check the other F4 series TBS by opening TouchGFX Designer, clicking on "Create new" and typing "f4" to see al the available TBS for F4 series boards:

You can also check some videos, here is a complete but long one : How to integrate TouchGFX in a custom board 

 

I hope this helps.

Thanks for your quick reply @GaetanGodart

I already watched that video https://youtu.be/SRQD8JMeg_k?si=oWqNTiEddbzsl_pj

Here, STM32F413ZHT6 does not have LTDC. So I'm using FSMC as a LCD interface.

Marudhupandian_0-1725277210389.png

 

I create a TouchGFX project via STM32CubeIDE-> TouchGFX-> ApplicationTemplate.touchgfx.part 

Then I created an example project.

Marudhupandian_2-1725277465562.png

 

Marudhupandian_1-1725277447458.png

 

Then I run a TouchGFX project and refresh it. After compile successfully. In between that where I put a LCD initialization code?

 

When I enter the Program and run target. I got failed message.

Like:

No problem!

The error happens during compilation.
Apparently, there is no Makefile.
Can you check that you have a Makefile in the gcc fodler?

If you don't, you should create one (you can get very inspired by the ones we created for boards similar to yours).

This is my make file;

This make file seems to only be good to run the simulator as it seems to call "make generated/simulator/gcc/Makefile".
I could be wrong though.

Do you have a Mafekile in generated/simulator/gcc?

Yes, I've Makefile in generated/simulator/gcc

Hello @Marudhupandian ,

 

Are you sure that you have a gcc folder and a Makefile in it?
When I look at your screenshots, I see that you have the TouchGFX folder but I do not see the gcc folder.
The TouchGFX and gcc folder should be at the same level :

Can you double check that please?

Hi @GaetanGodart 

You are correct. I don't have gcc file. How to make gcc file.
