Display the camera image using TouchGFX.

Hi ,

I'm developing a product on an STM32N6 using TouchGFX. I need to display the image coming from the camera input on the product on the TouchGFX. During our tests, we were able to directly print the image from the DCMI input to the screen and it worked. However, we need an example that takes this image and displays it on the TouchGFX. The AI example prepared for the N6 actually includes this type of work, but the code is not accessible. Could you please share the relevant project or the relevant part so I can integrate it into my project, or could you provide an example project for this?

What camera?

What product?

How to write your question to maximize your chances to find a solution

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I asked a very clear, general question.

I'm developing an HMI using the STM32N655. I'm using a PAL analog camera connected to the DCMI interface with this MCU. In our work, we displayed the camera image coming from DCMI directly on our screen via the LTDC interface using DMA. This was a test for hardware validation.

Currently, I'm working on displaying the live camera image from DCMI on the HMI I'm developing. Therefore, I need an example that displays the image from the DCMI interface using a widget on TouchGFX for the STM32N655.

I also have an STM32N6-DK. This demo kit includes a camera. In the demo software, the image from the camera is displayed to the user on the screen. If possible, I would prefer to share this example.
