V4L2 mode for Raspberry Pi
How to use VEYE and CS series camera module on Raspberry Pi(V4L2 mode)
1 Introduction
For the use of VEYE series and CS series camera modules on the raspberry Pi platform, we provide veye_raspicam software, an application layer open source software similar to the raspicam. This series of software, without driver support, has good compatibility with different versions of piOS.
However, we think that the V4L2 driver mode also has a wide range of applications. The two modes cannot be used at the same time, which is embodied in whether the driver is installed or not. It will be described in detail later.
This article describes how to call the camera modules of VEYE series and CS series through V4L2 on the raspberry Pi platform.
2 Hardware Setup
VEYE series camera module setup on rpi
CS series camera module setup on rpi
3 RaspberryPi System Setup and Configuration
RaspberryPi System Setup and Configuration
4 Driver Installation
4.1 Download the driver
git clone https://github.com/veyeimaging/raspberrypi_v4l2.git
4.2 Install the driver
cd raspberrypi_v4l2/release/
chmod +x *
sudo ./install_driver.sh [camera module]
camera module：could be veye327,csimx307,cssc132.
4.3 Uninstall the driver
If you need to change to using the camera by veye_raspicam software, or if you want to change to a driver of another camera module model, you must first uninstall the current driver.
sudo ./uninstall_driver.sh [camera module]
camera module：could be veye327,csimx307,cssc132.
5 Check and Test the Camera
Check the camera probe status
- VEYE-MIPI-327
dmesg | grep veye
You can see:
veye327 camera probed
- CS-MIPI-IMX307
dmesg | grep 307
You can see:
camera id is cs-mipi-imx307
- CS-MIPI-SC132
dmesg | grep 132
You can see:
camera id is cs-mipi-sc132
5.1 List the video device
ls /dev/video0
The device node exsit.
5.2 List the available video modes
v4l2-ctl --list-formats-ext

7 Video Control Toolkits Manual
Because of the high flexibility of our camera parameters, we do not use V4L2 parameters to control, but use scripts to configure parameters.

8 Source code cross compilation
The main resources in this section are the official piOS building method. We use the method of cross-compilation, and the 5.4.72 version of 32bitOS is taken as an example.
The following operations are done on ubuntu PC.
