Issue on connecting B-CAMS-OMV to STM32H747I-DISCO for video streaming #1

Description: I am working on a project to connect the B-CAMS-OMV camera module to the STM32H747I-DISCO board to stream video onto the inbuilt display. However, I’m facing difficulties getting the video to display. Below are the details of my setup, steps I’ve tried, and the specific problem I’m encountering.

Steps to Reproduce: Configured the DCMI on STM32H747I-DISCO to capture video from B-CAMS-OMV. Set up the display using LTDC (LCD-TFT Display Controller). Verified pin connections and checked clock settings in STM32CubeMX.

Expected Behavior: The video stream from the B-CAMS-OMV should display on the STM32H747I-DISCO’s screen.

Actual Behavior: The display remains blank with no video feed or data from the camera. No errors appear during compilation, so it’s unclear if the issue is with configuration or data handling.

System Configuration: Camera Module: B-CAMS-OMV, 8-bit interface. Microcontroller Board: STM32H747I-DISCO Tools Used: STM32CubeMX, STM32CubeIDE Display Resolution: 800x480

Request for Assistance: Guidance on correct DCMI and LTDC configuration for an 8-bit camera module. Any troubleshooting tips for verifying camera data stream. Sample code or similar configurations, if available.

Additional Context: Add any relevant links, screenshots, or configuration files that could help explain your issue further.

@Dinesh2613 I had a project that was also using stm32h7 with B-CAMS-OMV. Check out: https://github.com/PawelLawrynowicz/discovision. First check if your LCD is configured correctly (you can display anything at all). If thats the case there is probably some issue with camera's configuration. For us it was one of the clocks that was running too slow. Hope you can figure it out from here.
