Interfacing with hardware in TouchGFX Applications

[Martin KJELDSEN]

Due to popular demand, here's the information we have on interfacing with peripherals on an STM32F769-DISCO board in a TouchGFX Application.

I have two resources for this:

1. Video: I did a webinar last year on this topic where we create an application using v4.9.3 of the TouchGFX designer and interact with push buttons through a GUI + turn on an LED using a TouchGFX Button: https://www.youtube.com/watch?v=jQO7zhX0e0Q
2. Article: https://support.touchgfx.com/docs/development/ui-development/touchgfx-engine-features/backend-communication/. Here are the direct links for the demos i did in TouchGFX 4.9.3 (should be upgradeable) using GPIO and EXTI approach: EXTI, GPIO.

Disclaimer: The examples in the article are not maintained throughout new versions of TouchGFX.

Feel free to comment if you have any issues. Thank you!

Best regards,

Martin

Hi @Martin KJELDSEN​ ,

Could you please provide the project file of the hardware integration project demonstrated in the Youtube webinar video? I went through the link in the comment section but it's broken.

Thanks,
