Hardware button with TouchGFX for screen transition

[Josh_W020]

Hi,

I have been trying to implement the functionality to change the currently active screen on TouchGFX using a hardware button with no luck so far.

I'm using an STM32H743zit6.

Here are the resources I've looked at but haven't managed to get working:

Any help would be greatly appreciated,

Thanks.

Which part are you stuck on:

• change the currently active screen?
• detecting a hardware button?

Hello,

I think you need to use application().gotoScreen2CoverTransitionxxx() API from the button callback.

See for example this thread.

Ohh boy zero info... Try this

run simultor and press A key on keyboard Work transition ?

Interaction1 in my example is add on main screen (FYI your screen marked to start) and transition go to Screen1...

When this works ok you can step to physical button code ...
