Custom project set up using Touch GFX on Riverdi STM32H7 Embedded Display

[koderboi22]

I have generated a new project with Touch GFX Designer where I created a text area and also created a button, to which I have linked an interaction. This interaction will call on a new virtual function which I then plan on integrating with my external project files. I've created my projects .c and .h files in which I'm writing a simple arithmetic calculation. Note that my project files are in C whereas the Touch GFX generated files are in C++, I now want to call the arithmetic function in the model.cpp file and I'm unable to run the simulator on the Designer as it gives me an error. 

File Path for Touch GFX generated files -> C:\TouchGFXProjects\MyApplication_2\CM7\TouchGFX\gui\src

Below are the files:

}

 presenter->MathTest(7, 4);



}



void Screen1View::GetResult(uint16_t Result){



   char buffer[20]; // Adjust the buffer size as needed

   snprintf(buffer, sizeof(buffer), "%u", Result);

   Unicode::strncpy(textArea1Buffer, buffer, TEXTAREA1_SIZE);

   textArea1.invalidate();

Hi @SofLit, I've made the changes as below but I'm getting an error message when I run the simulator:

This is the file path to the makefile: C:\TouchGFXProjects\Test\CM7\TouchGFX\simulator\gcc

Below is the makefile and as you can see in lines 24 and 25, we've added the additional source and include paths as you mentioned:

# Helper macros to convert spaces into question marks and back again
e :=
sp := $(e) $(e)
qs = $(subst ?,$(sp),$1)
sq = $(subst $(sp),?,$1)

# Get name of this Makefile (avoid getting word 0 and a starting space)
makefile_name := $(wordlist 1,1000,$(MAKEFILE_LIST))

# Get path of this Makefile
makefile_path := $(call qs,$(dir $(call sq,$(abspath $(call sq,$(makefile_name))))))

# Get path where the Application is
application_path := $(call qs,$(abspath $(call sq,$(makefile_path)../..)))

.PHONY: clean assets all

ifneq ($(words $(makefile_path))$(words $(MAKEFILE_LIST)),11)
all clean assets:
$(error Spaces not allowed in path)

Hello @koderboi22 ,

Your architecture is correct, however, you have defined the include files to be called when the simulator is not running and then you have set to call the function MathOp when the simulator is running. So, if you like to test your code in simulator, you should either remove the Marcos for the simulator or set them both to #ifdef simulator

I hope this helps you, don't hesitate to ask more questions.

@Mohammad MORADI ESFAHANIASL 

Indeed, I didn't see this part of code:

#ifndef SIMULATOR

#include "Mytest.h"

#include "stdio.h"

#endif

 I focused on the makefile!

[koderboi22]

Hi @Mohammad MORADI ESFAHANIASL ,

I have removed them both from the #ifndef SIMULATOR now:

#ifndef SIMULATOR

#include <gui/model/Model.hpp>

#include <gui/model/ModelListener.hpp>

#else

#include "C:/TouchGFXProjects/Test/CM7/Core/Inc/Mytest.h"

#endif



// Define the constructor for the Model class

Model::Model() : modelListener(0) {}



// Define the tick function for the Model class

void Model::tick() {}



// Define the MathTest function for the Model class

uint16_t Model::MathTest(uint16_t x, uint16_t y) {



#ifndef SIMULATOR

   // Include header and call MathOp function when not running in the simulator

   return 0;

#else

   // When running in the simulator, just return the sum of x and y

   uint16_t Result = MathOp(x, y);

   modelListener->GetResult(Result);

   return Result;

#endif

}

If not, can you please guide how to fix this.

Furthermore, I'm still receiving the same error as well.

[SofLit]

No.

Since you are using the simulator you need to define the flag SIMULATOR:

Replace:

#ifndef SIMULATOR

by

#ifdef SIMULATOR

So you need to remove 'n' from #ifndef

Or simply remove this definition.

[koderboi22]

I've done this however when I now build the code it says, that there is an undefined reference to the MathOp function.

[SofLit]

You need to add Mytest.c file to your project. To my knowledge in the Makefile under simulator\gcc:

ADDITIONAL_SOURCES := ../CM7/Core/Src/Mytest.c

[koderboi22]

So I've made both the changes as you mentioned however still I'm receiving the error, if there is a way to set up a meeting of some kind it'll be great help.

[SofLit]

Unfortunately, no meeting is possible.

If you can attach your project so TouchGFX experts can help you. 

If not possible, as said previously, you need to contact your local FAE for an efficient assistance.
