STM32F469I-Discovery TouchGFX not working

[LDini.1]

Hello,

i need to setup a TouchGFX project for STM32F469i-Discovery.

I tried to create the project via STMCubeIDE with the TouchGFX Software Package.

But the Screen remains black.

I created the project in following steps:

1. Create Project from STMCubeIDE v. 1.10.1 and Board-Selector with default Values
2. Added Software Package TouchGFX 20.0
3. Configured LTDC, DISI Host and TouchGFX Graphic Application
4. Created TouchGFX Project from TouchGFX/ApplicationTemplate
5. tried to run the project without success

Is there something extra I need to do/implement ?

I already added the /BSP/Components and /BSP/STM32F469I-Discovery Folder

and managed to turn on the Display myself. But I still cant manage to display content on it.

Do i need to write code into the /TouchGFX/target c++ files?

I also created a second project with just TouchGFX Designer, but after running target the screen remains black too.

So neither STMCubeIDE or TouchGFX work for me. But the demo projects work perfectly.

I'm using STMCubeIDE version 1.10.1, TouchGFX Designer version 4.20.0 and Firmware Version 1.27.1.

I have attached a .zip File with both Projects.

"MCU_Display" was made with Cube-IDE 1.10.1 and TouchGFX 20.0

"TouchGFX" was made with TouchGFX Designer 20.0

I'm really looking forward for you replies, since I've been trying to get this running for a week of work now.

Thank you very much

Regards Luis

Hello LDini.1,

Might be related to drivers according to this thread but needs more investigation on our side. If it's the case, we'll need to find a way to make the TBS compatible with different screens (so different revisions of this board).

I don't have a workaround to suggest you yet, but I think this is not something patchable with STM32CubeMX configuration.

Hello,

sorry to bother you again.

We're thinking about buying a STM32F769I-EVAL Board.

Are there any problems considering TouchGFX known ?

Thank you very much

@Osman SOYKURT​ Any update / workaround for this issue (ticket n°138075)?

Hello JJaco.7,

Did you try @Romain DIELEMAN​ 's solution on this thread? We're waiting for the delivery of this board revision, couldn't test it here yet.

Got it up and running with TouchGFX in the meantime.

The LCD_Reset pin should indeed be set to PP instead of OD.

If anyone is interested, please let me know. Do not have an example application right now, just my actual project which I cannot share.

Created an example application with TouchGFX for board B08:

Binary:

Hello LDini.1,

A new TBS is now available on TouchGFX Designer 4.21.0 for this STM32F469I-Disco $AU1 revision (B08)

 

It should resolve the issue with the black screen.
