STM32N6570-DK How to use Camera(DCMIPP?)-Display with touchGFX GUI

[JinukLee]

Hello ST Team,

I am working with the STM32N6570-DK board and trying to display the live camera feed on a TouchGFX application.

I cannot find any ready-to-use example that integrates DCMIPP (Camera) and TouchGFX.

Current Situation:

1. TouchGFX Designer: I have created a UI with a transparent area in the center (Alpha = 0) to display the camera feed. (Please see the attached screenshot).

2. Cube IDE Firmware:  I found the DCMIPP_ContinuousMode example and confirmed that it works fine independently. However, merging it into a TouchGFX project manually is quite difficult for me.

My Question:
Is there a simple, official example or Application Note demonstrating Camera Preview (maybe on Layer 0) + TouchGFX UI (maybe on Layer 1) for the STM32N6570-DK?

Since I am new to the STM32N6 series, a detailed, step-by-step explanation would be very helpful.

I would appreciate a quick guide or a GitHub link.
Thanks.

Hello,

From my understanding, the video frame must be resync by the TouchGFx engine.

You can refer to the following documentation :

MJPEG Video | TouchGFX Documentation

I would start the trial with simple jpeg picture from the camera (DCMIPP+VENC) then configure Touchgfx to linked the image output buffer to the input widget cf Decoding Strategies chapter.

Regards,

Simon
