Overview
7+
********
8+
9+
This shield supports mt9m114 camera modules which use a 24-pin FPC connector and a DVP
10+
(Digital Video Port), aka parallel interface. These camera modules are compatible and provided
11+
together with the i.MX RT1050, RT1060 and RT1064 EVKs as specified here `Camera iMXRT`_.

Requirements
70+
************
71+
72+
This shield can only be used with a board which provides a configuration for a 24-pins FPC
73+
connector with DVP (parallel) interface, such as the i.MX RT1050, RT1060, RT1064 EVKs.
74+
75+
Programming
76+
***********
77+
78+
Set ``-DSHIELD=dvp_fpc24_mt9m114`` when you invoke ``west build``. For example:
79+
80+
.. zephyr-app-commands::
81+
:zephyr-app: samples/subsys/video/capture
82+
:board: mimxrt1064_evk
83+
:shield: dvp_fpc24_mt9m114
84+
:goals: build
85+
