And do you have something working now?

[KM L.1]

No

[Martin KJELDSEN]

Are you expecting some sort of help from me? I can't really tell.

[KM L.1]

yes very much....

[Martin KJELDSEN]

Then go ahead and explain to me what isn't working, what you're having issues with and how you'd like me to help.

[KM L.1]

I'm generating code in stm32cubeIDE and I wanted to communicate between hardware button and touchgfx GUI. But I'm unable to integrate HAL function with touchgfx .

I went through the article which you had sent but I don't have clarity where to write the code to use external event as trigger.

"But I'm unable to integrate HAL function with touchgfx ." - Please elaborate. What does this mean?

Do you have any code that correctly samples the joystick?

[KM L.1]

Ya I have code for joystick which I have worked on Keil….

[Martin KJELDSEN]

It's impossible for me to help you if you don't give me more details on what you need help with and what your issues are.

First thing is I wanted to know how to communicate between hardware button and touchGFX.

Then how to make hardware button to act as trigger as I went through your article I didn't get where to add that piece of code .

As I'm new for touchGFX and c++ I don't know how to integrate the joystick part with the touchGFX QWERTY keypad code . The thing is I wanted to operate QWERTY keypad using joystick buttons which is on eval board without using touch.
