VEYE-MIPI-290/327 is a is a special camera module which is compatible with RASPBERRY PI. She use SONY STARVIS sensor——IMX290/IMX327 and has excellent ISP functions build-in.The output format is stanard UYVY stream. It is very easy to use it with RASPBERRY PI.Of course, she also has some subtle differences with the official version. She only support 1080p resolution,and i2c cmd is different.

Theoretically,VEYE Camera Modules support all Raspberry Pi. For performance reasons, I recommend you use 3,3+,4 version.  This article uses Raspberry Pi 3B as an example to explain how the VEYE-MIPI-290/327 camera module working with  Raspberry Pi.  It also explain the specials  of RPI Computer Module and Zero using VEYE Camera Module.

'''Essentials You Need：'''
 +
 
 +
*Raspberry PI Items : RPI, Network, MicroSD Card, Power, Monitor
 +
*Camera Module Items : VEYE-MIPI-290/327，FFC，Dupont Wire，Lens，Adaptor Board. （We developed 2 types of adaptor boards, [[Mini Adapter Board|Mini Adaptor Board]] and [[Adapter Board for Raspberry Pi|Adaptor Board]]. Mini board only support Standard RPI，Adaptor Board support both Standard RPI and CM & Zero.)

====Toolkits Overview====
 +
[[File:Rpi github overview.jpg|alt=|center|thumb|600x600px|Software Tookits on github]]
 +
Software toolkits contains three parts. ''veye_raspcam'' is raspcam alike Video Stream Toolkits, D_mipi_rpi is D-SDK Video Stream Toolkits, ''i2c_cmd'' is Video Control Toolkits.
 +
 +
*Video Stream Tookkits provides real-time display, capture, video recording, etc.
 +
*Video Control Toolkits is a shell script which provides ISP parameters configuration capbility.
 +
*Both is Open Source.<br />

===Video Control Toolkits Manual===
 
===Video Control Toolkits Manual===
 +
On Raspberry Pi, I2C-0 is used by GPU. We use I2C-1 as control bus for VEYE Camera Module. We provide a Shell Script — camera_i2c_config— to config pin usage.

===RPI Computer Module and RPI Zero Additional Info===
 
===RPI Computer Module and RPI Zero Additional Info===
 +
 +
====Overview====
 +
RPI CM and Zero have a different MIPI CSI-2 port with standard RPI. And CM has can support dual cameras. Here I use a VEYE-MIPI-290/327 and a RPI CM3 as an example.
 +
 +
PS： I use a Computer Module IO Board Plus designed by [http://www.waveshare.net/ WAVESHARE ELECTRONICS]. The official CMIO Board is similar.
 +
 +
====Hardware Setup====
 +
 +
=====Connecting Video Stream Port=====
 +
 +
*Connect the VEYE Camera Module the CSI-2 port using FFC Cable（'''type A''').
 +
*Connect Dupont Line as shown below. VEYE-MIPI-290/327 need an addtional power.
 +
*CM3 can support dual cameras.
 +
 +
=====Connecting I2C to CMIO=====
 +
 +
*CAM1：
 +
 +
Attach CD1_SDA to GPIO2 .
 +
 +
Attach CD1_SCL to GPIO3 .
 +
 +
*CAM0：
 +
 +
Attach CD0_SDA to GPIO44 .
 +
 +
Attach  CD0_SCL  to GPIO45 .
 +
 +
For RPI official CMIO board, please refer to [https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-camera.md Link].
 +
 +
For WAVESHARE CMIO board, as shown below.

====System Setup and Configuration====
 +
For RPI official CMIO board, please refer to [https://www.raspberrypi.org/documentation/hardware/computemodule/cm-emmc-flashing.md Link].
 +
 +
For WAVESHARE CMIO board, please refer to [http://www.waveshare.net/w/upload/4/46/Compute_Module_IO_Board_PLUS_User_Manual.pdf Link]，Page 7.
 +
====Video Stream Toolkits====
 +
All command support  [-cs] option.
 +
 +
option -cs 0 to control CAM0, -cs 1 to control CAM1. For example:
 +
 +
*veye_raspipreview
 +
 +
<code>./veye_raspipreview -cs 0 -t 20000</code>
 +
 +
Dispaly real-time video to HDMI output,from CAM0, lasts 20 seconds.
 +
 +
*veye_raspivid
 +
 +
<code>./veye_raspivid -cs 1 -t 5000 -o ~/test.h264</code>
 +
 +
Implement H.264 format encoding and record for 5 seconds from camera 1，Record the stream data to file ~/test.h264.<br />
 +
====Video Control Toolkits====
 +
Downloading dt-blob.bin file from link,and upload it to /root/,reboot RPI.
 +
 +
CM3 use I2C-1 to control 2 cameras，It is time-sharing multiplexing.
 +
 +
<code>./camera_i2c_config [cameranum]</code>
 +

 +
<br />Other options see : [[VEYE-MIPI-290/327 i2c/zh|VEYE-MIPI-290/327 i2c]]
 +
===FFC Cable Remarks===
 +
 +
*For Standard RPI，use FFC cable TypeB.
 +
 +
[[File:Veye Base Adapter FFC.jpg|center|thumb|600x600px|FFC Cable TypeB.]]
 +
 +
*For RPI CM3 ，use FFC cable TypeA.
