TouchGFX Designer does not generate Text code (Text.cpp)

[GS1]

Hi all,

Hi Martin,@Martin KJELDSEN, 

now that version 4.26.0.  of TouchGFX is out, I tried to migrate my huge project (90 screens) to this new release, but I can not get texts being generated.

What I have done:

I used the latest STM32CubeMX version (6.15.0) and regenerated code of the project with TouchGFX Version 4.26.0 selected. Then I opened TouchGFX Designer 4.26.0, migrated my project and generated code too.

There were several warnings concerning the Unicode characters like the following sample:

WARNING - Char 0xC0 is used but does not exist in the font!
WARNING - A total of 64 Unicode characters did not exist in the font!

In the first run, texts were generated correctly.

But as soon as I change a text or add a new text, these changes are no longer regenerated when pressing "Generate code".

Then I tried several things (proposed on a different post):

- Change all wildcard character sets from 0x20...0xFF  to 0x20...0x7E.   Did not help!

- Generate a blank (Simulator) app and imported the GUI: Text generation then works! But I need the design im my project folder, therefore:

- I then tried to import this GUI back into my original project: Text generation doesn't work then!

- I tried to generate a new (simulator) design in my current project folder and import from the working generated new project: Text generation still doesn't work.

I am out of ideas, how to fix this issue!

Can anyone tell, what is wrong and how I can fix this?

P.S: Version 4.24.1. ist the last working version for me. This issue arose with Version 4.25.0. already. 

Please can anyone of the employees have a look, what was changed from 4.24.1 to 4.25.0 so that these releases don't generate text anymore??

Thanks for help.

Hello @GS1,

Have you check if your project uses char 0xC0 and if your font contains it too ? You can use FontForge to check that.

Hi Louis,

I only use 3 font types: Calibri, CalibriB (Bold) and AbsolutDB (ABSN_.TTF)

Using FontForge I see that both fonts should have 0xC0. This is a character which I don't use in my application (À).

I only use the german " äöü ÄÖÜ ß " and the  "  ² " character from the calibri fonts, but these are available in the font. 

Any other possible reason?

Could you send me the fonts ?

Hi Louis,

I have done another try, which also failed:

I redefined the Wildcard character sets to only have 0x20 - 0x7E (instead of 0xFF).

This eliminated the WARNING messages, however changes in the texts are still not generated.

In Version 4.24.1 everything is working perfectly.

I have attached a zip file with my 3 fonts.

Hope you can find a reason...

Hello @GS1 ,

Have you tried to delete the generated folder and regenerate ?

BR,

[GS1]

Yes, I tried that. Then this folder is not regenerated.

Can you try with different fonts (only use verdana for all your typo) ? Can you send the log output ?

[GS1]

After changing the Typographies of my several font sizes from Calibri to Verdana and changing the contents of 2 texts to make sure, that texts need to be generated,  the only thing that happens is as follows:

- in the asset \ fonts folder the verdana.ttf is added 

In the sub folder under "generated" for text and fonts:

- text source files are not created. Previous files are untouched

- font source files for the different typography are not created. Only the Calibri files still exist untouched.

The log is as follows (don't know where to find a file):

Then I deleted the complete folder "generated" and pressed "Generate code" again.

This should regenerate all sub-folders and files.

But the only subfolder in "generated" now are: 

- gui_generated

- simulator

and a file named user.config

Missing folders: 

- fonts

- texts

- images

- videos (which I actually don't use/need) 

Please note: 

I am not using the Simulator (this is not possible in the current configuration) and therefore I deleted the command calls in the Config-build setup for the simulator creation. Same applies for the Target, because the target is created with Keil separately. The TouchGFX application is running on a custom board with 2 processors, which are loaded separately via my own lootloader into system. The 2 processors have different tasks to aquire data from CAN busses, store data to SD card and flash, etc. The 2  STM32H7A3  communicate via internal SPI ports.
