CubeMX5.2/TouchGFX4.10.0/STCUBEIDE1.0 or SW4STM32 or TrueAtollic working properly with 32F746NGDiscovery

[KMunj]

Has anyone got CubeMX5.2/TouchGFX4.10.0/STCUBEIDE1.0 or SW4STM32 or TrueAtollic working properly with any Discovery board? I mean be able to build with no errors and ​run it on any Discovery board? I had it working with CubeMX4.xx/TouchGFX4.10.0/SW4STM32. But when I  updated CubeMX4.xx to 5.2, I get build errors. I tried the procedure put by Zhi Pang on the community, but it doesn't work anymore. I get build errors.

If you have it working please send me some info on how you did it.

Thanks

Hi @KMunj​,

There are some quirks to work out, but it should be possible to, with a little bit of effort, make TouchGFX run on a disco board with a parallel RGB screen. e.g. STM32F746G-DISCO.

Can you tell me how far you got? I will write a sticky with some of the initial issues we've identified here re: TouchGFX/CubeIDE integration.

​Thanks Martin for responding.

I am using 32F746Discovery Board as per your recommendation. Unfortunately I can't make much progress. I get errors immediately.

I open IDE and select 32F746Discovery. I keep all the defaults and name the project and open. Then I select graphics and select TouchGFX. I make sure every thing in that window is correct. (Attached -2). Then I do "Clean Build" and "Build". I get 4 errors. (Attached -3). So I do "Clean Build" and do "Execute" TouchGFX. It gets started and gives error "Error during code generation" (Attached -4). Then I tried to build the code, but IDE gets hung up.

Next time around, I did "Execute" 1st before and clean/build. But TouchGFX give same error "Error during code generation". I also selected C++ instead of C as Targeted language, but no matter I can't get rid of "Error during code generation" on TouchGFX.

If you need additional, info please let me know.

Thanks

​Looks like I can do only one attachment.

Here is -2.

Hi @KMunj​,

I created a sticky that should help you through creating a CubeIDE/TouchGFX project. Some of the issues you're having here are addressed there, i believe. Try it out and let me know, okay?

Thanks!

Best regards,

Martin

​Thanks, Martin. I would like to try this sticky. But where can I find it. I searched under your name on the Community but couldn't find it. I tried to google it too. But no luck.

Please provide the link to this sticky for creating a CubeIDE/TouchGFX project.

Thanks.

At the top of the TouchGFX subforum (this forum). Here's the direct link.

Hope it helps!

​Thanks, Martin.

I don't know how to do #7. Is there any sticky for following how to do this?

1. The library settings are wrong. Include the touchgfx library in MCU G++ Linker\Libraries:
   1. Libraries (-I): touchgfx-float-abi-hard
   2. Libraries search path (-L): \Middlewares\ST\TouchGFX\touchgfx\lib\core\cortex_mx\gcc\

Thanks.

Hi @KMunj​,

I'll update the description to be more concise - Here's a few screenshots of how to do this:

​Thanks, Martin.

I followed all your steps, but something is still missing.

In your step 3, I added LCD Reset Pin XRES = PI12. This was required to make TouchGFX OK to Execute.

Without clicking Execute I built the project, but I got 7 errors. Please see attached.

Then I went thru rest of the steps. When I went to step 8 and built the code again, IDE got hung up.

I waited for 15 minutes, but no luck.

Thanks

These errors seem to indicate that you did not Execute the TouchGFX designer (not saying you didn't :) ) - Because those files should get generated into your project folder.

Thanks for the hint about LCD reset pin - You're right i accidentally left that out.

[KMunj]

​Now I opened the windows task manager and killed the IDE.

I reopened the IDE and built the project again. This time it didn't get hung up, but got 3 errors.

Please see attached.

Thanks

Kiran

You have not excluded the simulator folder from compilation. I think CubeIDE/CubeMX reset / overwrote your local project changes if you re-generated code. You probably weren't getting those errors the first time around.
