DCMIPP overview

DCMIPP overview}

  • Pipe 1 is enabled using CMW_CAMERA_Start(DCMIPP_PIPE1, *ptr_dst, CAMERA_MODE_CONTINUOUS); to continuously transmit images from imx335 to the LTDC frame buffer (lcd_bg_framebuffer).
  • Pipe 2 is enabled using CMW_CAMERA_Start(DCMIPP_PIPE2, *ptr_dst, CAMERA_MODE_SNAPSHOT); to capture one frame (in the nn_in buffer) before launching the inference in the NPU.
  • For each capture the ISP configuration is updated to enhance the image quality depending on the illumination conditions. It is initialized through ISP_Init and then executed with ISP_BackgroundProcess.

For more details of DCMIPP see Digital camera interface pixel pipeline (DCMIPP) in STM32N6 Reference manual.
