How to use VEYE-MIPI-X series camera module on Raspberry Pi（legacy mode）

1 Introduction

VEYE-MIPI-X is a is a special camera module which is compatible with RASPBERRY PI. It 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.

2 About piOS---Bullseye

The latest system of Raspberry Pi - bullseye has removed the support of raspicam by default. But we still have 2 ways to use it.

• 1, Use the legacy version of the OS, that is, do not upgrade to Bullseye.

https://www.raspberrypi.com/software/operating-systems/

• 2, Open legacy camera support in raspi-config on Bullseye. We have upgraded the program to accommodate this usage.

If you want to add the legacy camera interfaces to Bullseye, please click your update icon in the taskbar to update. Then open a terminal (Ctrl-Alt-T) and type ‘sudo raspi-config’, go to ‘Interface Options’ and then ‘Legacy Camera’, and reboot. These camera interfaces are deprecated, and we are not supporting them going forwards.

By the way, Use this cmd to check your system version:

lsb_release -a

3 Hardware Setup

Essentials You Need：

• Raspberry PI Items : RPI, Network, MicroSD Card, Power, Monitor

5 Sofware Toolkits Install

5.1 Toolkits downloading

There are two way to install software toolkits.

• 1. Clone from github

git clone https://github.com/veyeimaging/raspberrypi.git

• 2. Downloading from github (link here), upload to RPI using samba or USB disk.

5.2 Toolkits Overview

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.

7 Video Control Toolkits Manual

On Raspberry Pi, We use I2C-0 as control bus for VEYE Camera Module. We provide a Shell Script — camera_i2c_config— to config pin usage.

Video Control Toolkits Manual : VEYE-MIPI-290/327 i2c

The new version of PiOS use i2c-10. If i2c-10 doesn't work, try -b 0.

8 RPI Computer Module and RPI Zero Additional Info

8.1 Overview

RPI CM and Zero have a different MIPI CSI-2 port with standard RPI. And CM has can support dual cameras.

For CM3, I use a Computer Module IO Board Plus designed by WAVESHARE ELECTRONICS. The official CMIO Board is similar.

For CM4，I use official CMIO board.

8.2 Hardware Setup

8.2.1 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.

option -cs 0 to control CAM0, -cs 1 to control CAM1. For example:

• veye_raspipreview

./veye_raspipreview -cs 0 -t 20000

Dispaly real-time video to HDMI output,from CAM0, lasts 20 seconds.

• veye_raspivid

./veye_raspivid -cs 1 -t 5000 -o ~/test.h264

Implement H.264 format encoding and record for 5 seconds from camera 1，Record the stream data to file ~/test.h264.

8.5 Video Control Toolkits

Downloading dt-blob.bin file from link,rename to dt-blob.bin and upload it to /boot/,reboot RPI.

8.5.1 CM3

CM3 use I2C-1 to control 2 cameras，It is time-sharing multiplexing.

./camera_i2c_config [cameranum]

cameranum	description
0	CAM0
1	CAM1

./veye_mipi_i2c.sh -b 1

8.5.2 CM4

The CM4 module uses two I2C to communicate with two cameras respectively.

./camera_i2c_config

i2c bus num	description
0	CAM0
10	CAM1

./veye_mipi_i2c.sh -b [i2c bus num]
Other options see : VEYE-MIPI-290/327 i2c

9 FFC Cable Remarks

• For Standard RPI，use FFC cable TypeB.

FFC Cable TypeB.

• For RPI CM3 ，use FFC cable TypeA.

FFC Cable TypeA.
