Issue: Interfacing of STM32 H747I-DISCO Board with B-CAMS-OMV Camera Module and LCD

[mrinalinibarik]

Hello All, 

I'm currently working with the STM32 H747-DISCO board, but I'm encountering some difficulties in interfacing both the B-CAMS-OMV Camera Module and the LCD. After flashing the camera module, it successfully captures images, and I've also flashed the LCD, which displays the Embedded Wizard GUI. However, only one of them seems to be working at a time. Could you please advise if there are any steps I might be missing? Additionally, I'm seeking guidance on how to interface both the camera and LCD simultaneously. If there are any resources available, I'd appreciate it if you could share them with me.

Hello @mrinalinibarik ,

Many examples use the STM32 H747I-DISCO Board with B-CAMS-OMV Camera Module and LCD.

For that I a recommend you take a look at these examples like as:

• Examples  in FP-AI-VISION1 package.
• DCMI_CaptureMode this example explains how to use the DCMI to interface with a camera module and continuously capture images to a Camera Frame Buffer located in external SDRAM. Each camera image is then copied to the LCD display frame buffer using the DMA2D in ARGB8888 format.
• DCMI_SnapshotMode this example describes how to use the DCMI to interface with a camera module, capture a single image in Camera Frame Buffer (320x240 with RGB565 format) and once full frame camera is captured
  display it on the LCD in ARGB8888 format.

Thank you.
