Gauge application working directly from touchgfx but not working when trying to run it through STM32CubeIDE. Please help to solve this issue

[Alexandre RENOUX]

Hello,

I know it has been a while and sorry for that...

Could please elaborate your issue ? What board do you use ? What is the Gauge application you are talking about ?

What is the setup when it is working and when it is not with CubeIDE ?

This way we will be able to give you a proper answer.

Thanks for the reply.

I am talking about the application given on the link below:

https://github.com/touchgfx/touchgfx-open-repository/tree/master/widgets/Gauge

Using STM32F746G-DISCO board, STM32CubeIDE v1.2.0 and TouchGFX v 4.13.0

When implemented this Gauge example using TouchGFX directly then it worked.

But after adding same thing from STM32CubeIDE then the screen on which added this widget is not responding and the whole application freezes.

Hello,

When you say adding the same thing from CubeIDE, what exactly did you do ?

Are you using the AT 3.0.0 STM32F746G-DISCO available in TouchGFX Designer ?

I need more information to help you with your problem.

Yes I am using the AT 3.0.0 STM32F746G-DISCO available in TouchGFX Designer

I followed the procedure given on the link below:

https://www.youtube.com/watch?v=12KXreXaLp0

then added Gauge.cpp and Gauge.hpp files in the screen1_screen generated under TouchGFX/gui/ in the STM32CubeIDE.

Below is my Screen1View.hpp

#ifndef SCREEN1VIEW_HPP
#define SCREEN1VIEW_HPP
 
#include <gui_generated/screen1_screen/Screen1ViewBase.hpp>
#include <gui/screen1_screen/Screen1Presenter.hpp>
#include <gui/screen1_screen/Gauge.hpp>
class Screen1View : public Screen1ViewBase
{
public:
    Screen1View();
    virtual ~Screen1View() {}
    virtual void setupScreen();
    virtual void tearDownScreen();
protected:
    Gauge MyGauge;
private:
    static const uint16_t CANVAS_BUFFER_SIZE = 7200;
    uint8_t canvasBuffer[CANVAS_BUFFER_SIZE];
};
 
#endif // SCREEN1VIEW_HPP

Basically tried to add Gauge widget in the generated project.

Hello,

To me the Youtube video you are referring to is a strange way to get the code up and running with CubeIDE.

Please follow these steps:

• Open Designer and select the AT v3.0.0 STM32F746G-DISCO
• Generate code from Designer
• Copy the Gauge.cpp and .hpp files respectively in TouchGFX\gui\src\common and TouchGFX\gui\include\gui\common
• Modify your Screen1View.cpp and .hpp accordingly
• You should have a folder called STM32CubeIDE/, enter this folder.
• Double-click on the .project, it will open the project in CubeIDE
• Include Gauge.cpp in your project by clicking and dragging the file from your Windows explorer to the folder architecture on the left (now CubeIDE knows that this file needs to be compiled)
• Build project
• If any errors, please post it here to see what's the problem

When I tried this debug halts and not enabling Resume button.

Following is the debug console data:

It suppose to enable Resume button (F8) but nothing happens even after 10 minutes.

Do you have any video tutorial for this?

Hello,

It looks like you can build the project correctly but you cannot download the binary file and debug (correct me if I'm wrong). It seems to me that it's a problem related to your ST-Link or your launch configuration. 

Can you check your launch configuration (right-click on project > Properties > Run/Debug settings > Edit) ?

This is my debug setting.

This setting works with my other projects.

[Alexandre RENOUX]

Hello,

The Debug probe should be ST-LINK (ST-LINK GDB server) and then enable external loader and select the correct one as shown below.

You can also uncheck "Verify Flash Download" to accelerate the download process.
