Hello,
I successfully solder and connect my FRDM-MCXN947 to OV7670 camera and LCD PAR-LCD-S035 since I am able to run the demo "Multiple face detection on MCXN947" provided using MCUXpresso Projects from Application Code Hub.
My problem is that I encounter the following issue executing the "frdmmcxn947_smartdma_camera_flexio_mculcd example" : only one line of the camera is displayed on the top of the LCD display.
I am running the latest MCUXpresso version (24.12)
I get the "frdmmcxn947_smartdma_camera_flexio_mculcd example" directly from MCUXpresso using "Welcome"->Import SDK Examples ->Go straight to the Wizard" then frdmmcxn947 board (SDK 2.x_MCXN947/version 2.16.100/Manifest 3.14.00), then "display_examples" then "smartdma_camera_flexio_mculcd".
This project compiles, download and executes correctly but I get a black lcd screen with only one line updated by the camera.
I read the doc given on AN14191.pdf ( on https://docs.nxp.com/bundle/AN14191/page/topics/software.html#topic_30f829c2-0650-45e1-ab55-32097902... ) but that doesn't help much to understand the poorly commented code of the example.
Many thanks for your help,
Thierry
Dear Alice,
Thank you so much, it works now : the problem was the source code example :
I used the one provided from the MCUxpresso interface (Import SDK Examples ->Go straight to the Wizard" then frdmmcxn947 board (SDK 2.x_MCXN947/version 2.16.100/Manifest 3.14.00), then "display_examples" then "smartdma_camera_flexio_mculcd")
which is faulty.
The AN14191SW.zip is perfect ! (and totaly different).
Have a nice day !
Hello @tgrandpi
Please download the code from the AN14191 resource https://www.nxp.com/docs/en/application-note-software/AN14191SW.zip .
I've tested it on my end, it works well.
Thank you.

Thank you Alice, but I already did that 3 modifications in order to run successfully the "Multiple face detection" demo.
So this is not a hardware problem since that demo work.
Thank you for your help.
Hello @tgrandpi
