7.13 CSI-DCMI
7.13.1 Description
The STM32MP135F-DK Discovery kit provides an external camera module with a 1/4" color CMOS UXGA
2-megapixel image sensor. A CSI-DCMI bridge deserializes data from the camera module, which are then
transmitted to the MPU.
The resolution is up to 1600 x 1200 with 20 frames per second.
Output signals are 8-bit RGB RAW.
The control signals are I2C5.
7.13.2 DCMI I/O interface
