x-cube-n6-camera-capture Application

Computer Vision application to capture video stream using USB UVC.

Streamed video format is 800x480 YUV422 at 30 frames per second.

Package Content

This package contains in the Binary directory ready-to-flash Intel hex files for STM32N6570-DK and NUCLEO-N657X0-Q platforms.

For each platform, there are two binary flavors:

• front: It's a selfie-like orientation.
• rear: It's a camera-like orientation.

Hardware Support

MB1939 STM32N6570-DK

• The board should be connected to the onboard ST-LINK debug adapter CN6 with a USB-C to USB-C cable to ensure sufficient power.

• An additional USB cable to connect USB1 (CN18) to the host computer for UVC streaming.

• OTP fuses are set in this example for xSPI IOs to get the maximum speed (200MHz) on xSPI interfaces.

• 3 cameras are supported:

  • MB1854B IMX335 (Default camera provided with the MB1939 STM32N6570-DK board)
  • STEVAL-55G1MBI VD55G1 camera module
  • STEVAL-66GYMAI VD66GY camera module

MB1940 NUCLEO-N657X0-Q

• The board should be connected to the onboard ST-LINK debug adapter CN10 with a USB-C to USB-C cable to ensure sufficient power.

• An additional USB cable to connect USB (CN8) to the host computer for UVC streaming.

• OTP fuses are set in this example for xSPI IOs to get the maximum speed (200MHz) on xSPI interfaces.

• 3 cameras are supported:

  • MB1854B IMX335
  • STEVAL-55G1MBI VD55G1 camera module
  • STEVAL-66GYMAI VD66GY camera module

Tools Version
