CubeIDE 1.0.0 + TouchGFX 4.10.0: Working project inside (STM32F746G-DISCO)

[Martin KJELDSEN]

Hello everyone,

Due to an increasing number of people having issues with CubeIDE and TouchGFX Integration i'm attaching a working project for STM32F746G-DISCO for your inspection - There were a good number of things to do before it worked, only some of which i highlighted in my quick-guide and even some of those steps were a bit ambiguous and could be executed in different ways.

I've written down what i've done to get this project working and i will use this in planning a video tutorial - It has to be somewhat official, so i can't simply start up the screencast and start talking. But i'll keep you updated.

This project worked for me. I successfully tried to modify the screen with TouchGFX and then I rebuilt the project with STM32Cube IDE.

Thank you Martin Kjeldsen for your help.

[Martin KJELDSEN]

Awesome, you're welcome! The slow boot time is because i created the project using the board selector, initializing peripherals with default values. This includes Ethernet and apparently that stack is very slow to start.

Very nice! And a project for STM32F469 Disco? Is it possible? :smiling_face_with_halo:

Thanks Martin

[shorai]

Me too.

[Martin KJELDSEN]

I will do the video first and then i may try to do more projects.

One word: AWESOME!

Thank you SO much for this @Martin KJELDSEN​

This is truly appreciated - works out-of-the.. well, not box, but zip file :D Amazing!

[Martin KJELDSEN]

Wohoo! Nice! Glad it works for you :)

​Hi Martin!

For me it doesn't worked.

After unpacking the 7z-file I saw that the  ".project/.cproject /.mxproject..."-files are completely empty? I'm able to open the "project from file System" with CubeIDE but there is no project afterwards at project explorer. I guess the reason for that are the empty project files.

Is there anything to do before?

[MSeit]

​Hi Martin!

Sorry - was my fault - the (company-) installed 7z tool was out of date... and therefore some files were empty...?

[Martin KJELDSEN]

So it's working for you now?

[MSeit]

Hi Martin!

YES!!! There was one warning while compiling – but nothing serious – and then display showed the two red and green boxes and buttons.

I also tried to do some changes with TouchGfx – so implemented two company backgrounds – and it worked from the first trial on!!

Later on I also changed names and behavior and properties of buttons inside TouchGfx, saved it, switched immediately to CubeIDE and the project compiled with all changes without any error! No need to generate code inside TouchGfx - only saving it.

Thanks a lot!!

I’ve seen that there are a huge number of differences to my first generated code (made with CubeIDE & TouchGfx like described by ST in former articles) especially also in the project preferences.

Some behavior of my CubeIDE was strange too before – could not “exclude from build�??? – and this also worked now. I guess you have had a lot of work to get it run ;-)?

Waiting for an instruction document or video or whatever to see the magic!

Best regards Marco

Thanks!

I was also able to modify the TouchGFX code, generate it, and flash the Disco board.

Looking forward to your video.

[Martin KJELDSEN]

Hope you enjoyed the video. I realize there are a few issues with it based on feedback from users that i may fix up.

Martin,

I am pretty new with the STM32 in general. I was adding some images into your example with TouchGFX and got the following error:

==========================================================================

............ region `FLASH' overflowed by 45788 bytes

collect2.exe: error: ld returned 1 exit status

make: *** [makefile:99: f746g-disco-test.elf] Error 1

"make -j8 all" terminated with exit code 2. Build might be incomplete.

==========================================================================

I have created other projects with TouchGFX that used more images in the past so it is likely your example project has something setup up differently that is causing it to use the flash differently. In those previous examples, I used the TouchGFX "run target" option which had no problems. When running your example, the "run target" button is disabled.

Any ideas on how to resolve this would be greatly appreciated.

[scottSD]

It looks like the flash is not setup with nearly enough flash space as is available for the STM32F746G-DISCO:

I found the following TouchGFX link discussing configuration of the STM32F746G-DISCO and it said to set this to 24 instead of 1:

https://touchgfx.zendesk.com/hc/en-us/articles/360019884752-Configuring-STM32F746G-DISCO

However, when I tried the configuration (by using the STM32CubeMX perspective in STM32CubeIDE) I got a different compile error altogether. This time, it is failing for not knowing where the TouchGFX simulator files (SDL2/SDL_video.h) . I ran into this error when trying to use STM32CubeIDE in the past and did not find a way to resolve this.

Interestingly, I ran into this same or a similar error when trying to get Atollic TrueSTUDIO to work with TouchGFS.

Any suggestions?

Hello Martin,

For now I'm using the working project you gave us. I'm creating a pulse generator for test equipment. You were speaking of a tutorial video in a previous comment , but I can't find the link ?

Best regards,

Valentin

[Martin KJELDSEN]

It's a sticky now in the TouchGFX sub-forum.

[Valentin Gros]

Ah ok I didn't see you updated it. Thank you, I'll watch it !

Hello Martin,

Your example works fine but It does not work anymore if I do any modification in the Designer !? If I try to (re) generate the code, I get this error:

and of course in Cube I also get errors:

I have also to re-exclude the simulator stuff folders and files...

Any ideas ?

Thanks in advance,

Hi @jea74​,

You must remove the "post generate" command in the .touchgfx project file. It's trying to execute sw4_project_updater.rb but it does not know CubeIDE. It's a bug that has been reported.
