The Raspberry Pi Foundation has updated several versions recently;
The use guide of C779/C790/X630 depends on the official Raspberry Pi OS version you are using. Different versions have different usage methods. If you have some questions, please contact us and attach the osversion you are using.(<span style="color:red;">Email: support@geekworm.com</span>)

Add the line if your shield support audio like C780C790
dtoverlay=tc358743-audio
please append the
If (and only if) you have a device such as the Auvidea B102 that supports the 22pin connector with all 4 lanes wired out(such as [[X1300]]), and are using a Compute Module with the CAM1 connector that also has all 4 lanes wired up, you can use

5. Reboot. If all is well you should get a /dev/video0 device, and "v4l2-ctl --list-devices" will tell you that it is provided by Unicam.
After connecting all the cables, power on the Raspberry Pi, the C779 /C790 indicator light is normally green, and after opening the Raspberry Pi terminal, enter the following command:
<pre>
pi@raspberrypi:~ $ ls /dev/video0
should now reflect the resolution detected.
8. The chip supports two formats - BGR3 RGB3(the default) and UYVY. BGR3 RGB3 is 24bpp, and UYVY is YUV4:2:2 16bpp.
Over the normal 2 CSI-2 lanes the data rate is such that BGR3 RGB3 can run at a maximum of 1080p30, whilst UYVY will go up to 1080p50. Use the following command to select UYVY, however your application may override that.
v4l2-ctl -v pixelformat=UYVY
