Pressing the button brings up the project screen ? I need to help

[H??el.19]

I uploaded the project in this image to stmf746g-disco This project has no interface

keil file of the project is here

then I made a simple interface using touchgfx

The problem is how do I integrate the interface code with my real project?

I've seen something like this done by doing some research and watching videos and I've tried

here I created a variable called "buttonclicked"

here already touch gfx has created their own

I'm getting an error here

and most importantly, I do not know how to do this after correcting the error

even if this error is resolved, I don't know how to integrate the next steps

need your help thank you.

in short, how do I integrate my project that I use to draw a wave in my keil project into touch gfx

When I press the RUN button, I want it to bring up the screen in the first image

So what I want to say above is that it has a very simple expression.

When I press the button I want me to open the main project page

this screen but

touch gfx projects are saved as .cpp, but my project is written in .c

[H??el.19.75]

I need to write c code to the function I created here but how do I write c code here? because folder is .cpp

[H??el.19.75]

Sorry, i'm not available for team viewer. You still haven't answered my question:

Are you willing to re-create your simple gui in TouchGFX? You're mixing two different ways of drawing a gui which just complicates things. Your gui seems simple enough to try to re-create.

c and c++ can coexist. If you're not willing to create your application in TouchGFX you may be able to program both applications separately onto the board, and when you press a button then have your program counter jump to the old application, and vice versa if you want to go back to TouchGFX.
