STM32H745, Use of TouchGFX, Ethernet and LwIP

[QRobe.1]

I am currently working on a project using TouchGFX, Ethernet an LwIP on a STM32H745I board and I was wondering if anyone has encountered a similar issue.

I am using :

• the firmware package v1.9 for the H7 (I also tried with the v1.10),
• TouchGFX 4.18 (I also tried with 4.19).

I generated a project with TouchGFX Designer, and imported it on CubeIDE.

Then, I opened the .ioc file for adding the features of Ethernet and LwIP.

After generating the code, it seems that I cannot compile it because "lwip.h" is nowhere to be found, eventhough I can do "open declaration" and it opens a file from the upper folders. Here is a look at the project folders :

There is a Middlewares folder in the upper part but there is no Middlewares folder in the lower part. I tried to generate a project with the H747 board and the Middlewares folder is generated along with other folders :

 

Has anyone encountered this? Is it meant to be used that way?

Dont start create custom projects from TouchGFX.

I am having the same issues, no matter what I have tried I can build in CubeIDE, generate code or simulate in touchGFX but using run target from touchGFX gives errors.

It seems like touchGFX will not acknowledge any include or source paths you add in CubeIDE. I have not been able to find a work around and havn't found much additional information online...ST doesn't even respond to others asking similar questions.

I thought all this would have been fixed in the latest update to 1.10 and 4.20 but I am very close to abandoning their products, way to many bugs and problems. Their are other displays with GUI software that is way easier to work with....or should I say, they actually work.

I can only repeat my first reply.

Normal way for project start is in IDE new project. After add software package touchgfx into it, you will see, that run on target is disabled.

TouchGFX projects is only for demo, learning code without changes or very simple modification.

Hi

I had similar problem when I was trying to add USB feature from CubeIDE, while project was created using TouchGFX. Everything was compiled from TouchGFX tool. On my side, adding relative path to directories with required header files and relative path to source files in makefile_appli file (in gcc directory) resolved all compilation errors.

Below screenshot with makefile_appli changes:
