Peripheral DCMIEdit

The Digital CaMera Interface (DCMI) is a synchronous parallel interface able to receive a high-speed data flow from an external CMOS camera module.

DescriptionEdit

The DCMI interface available on ETRA SOM is based on STM32MP1 SoC.

The DCMI port supports the following standards and features:

  • 8-, 10-, 12- or 14-bit parallel interface
  • embedded/external line and frame synchronization
    • note that the VSYNC external signal is not available if the NAND flash is populated on board of the SoM
  • continuous or snapshot mode
  • crop feature
  • supports the following data formats:
    • 8/10/12/14-bit progressive video: either monochrome or raw bayer
    • YCbCr 4:2:2 progressive video
    • RGB 565 progressive video
    • compressed data: JPEG

Pin mappingEdit

The Pin mapping is described in the Pinout table section
