Digital Camera Interface (DCMI) for STM32 MCUs

If you like it, share it

Below there is the diagram for interface a CCD DCMI camera to the STM32.

The reference application note is the AN5020.

STM32 MCUs embed a digital camera interface (DCMI), allowing connection to efficient parallel camera modules.
The AN5020 application note gives STM32 users a grasp of basic concepts, with easy-to-understand explanations of the features, architecture and configuration of the DCMI.
It is supported by an extensive set of detailed examples.
The STM32 that support DCMI interface are listed below.

  • STM32F2
  • STM32F4
  • STM32F7
  • STM32H7
  • STM32L4

For more info read the AN5020.

STM example

  • STM32 food recognition
    • The examples provided from STM (in the function pack) are food recognition applications.
    • They recognize among 18 classes of common food such as pizza, hamburger, and Caesar salad.
    • The kit is based on: STM32F4DIS-CAM (use the: OV9655 CMOS sensor connected via DCMI bus to STM32H7) + STM32H747I-DISCO (based on STM32H747XIH6)
