Overview
7+
********
8+
9+
The ArduCam CU450 OV5640 shield provides the OV5640 image sensor on a 40-pin FFC connector,
10+
supporting both the DVP (Digital Video Port) interface and the MIPI CSI-2 interface.
11+
It is designed specifically for the Renesas `EK-RA8P1`_ evaluation kit.

Requirements
102+
************
103+
104+
This shield requires a board with a 40-pin FFC connector. The Renesas EK-RA8P1
105+
evaluation kit is fully supported.
106+
107+
.. note::
108+
While the CU450 OV5640 module and connector provide both DVP and
109+
MIPI CSI-2 interfaces, only the DVP interface is currently supported
110+
on Renesas RA SoCs. MIPI CSI-2 is not yet supported on this platform.
111+
112+
Programming
113+
***********
114+
115+
Set ``--shield arducam_cu450_ov5640_dvp`` when you invoke ``west build``. For example:
116+
117+
.. zephyr-app-commands::
118+
:zephyr-app: samples/drivers/video/capture
119+
:board: ek_ra8p1/r7ka8p1kflcac/cm85
120+
:shield: arducam_cu450_ov5640_dvp
121+
:goals: build
122+
123+
