DVP FPC-24 MT9M114 Camera Module
################################
Overview
********
This shield supports mt9m114 camera modules which use a 24-pin FPC connector and a DVP
(Digital Video Port), aka parallel interface. These camera modules are compatible and provided
together with the i.MX RT1050, RT1060 and RT1064 EVKs as specified here `Camera iMXRT`_.

Requirements
************
This shield can only be used with a board which provides a configuration for a 24-pins FPC
connector with DVP (parallel) interface, such as the i.MX RT1050, RT1060, RT1064 EVKs.
Programming
***********
Set ``-DSHIELD=dvp_fpc24_mt9m114`` when you invoke ``west build``. For example:
.. zephyr-app-commands::
:zephyr-app: samples/subsys/video/capture
:board: mimxrt1064_evk
:shield: dvp_fpc24_mt9m114
:goals: build
