How to display string by calling function outside the touchGFX

[Paco]

Hi all.

I'm using STM32H747I-DISCO bord, and I am working on displaying string on LCD by using touchGFX.

By the way I want to display string by calling function which exists outside of touchGFX.

For example, the function is exists in GPIO interrupt handler or main function. When the function is called, touchGFX action react and display string. The action is configured to display string in response to the function call in advence.

In TouchGFX Tutorials, trigger example for LCD touch operation(click button,etc) is provided, but trigger example that is not related to touchGFX is not provided.

Please tell me how to display string by calling function outside the touchGFX.

Thank you in advance.

Hello @Paco,

By "When the function is called, touchGFX action react and display string", you mean that this function is called by another task that should then update the string ?
