CS-MIPI-X i2c
cs_mipi_i2c.sh Shell scripts usage
1 Introduction
The cs_mipi_i2c.sh script is a toolset for configuring CS-MIPI-X series cameras through the I2C.
2 RaspberryPi Only, Set IO config
Include the following files,camera_i2c_config、i2c_read、i2c_write、cs_mipi_i2c.sh.
Running
./enable_i2c_vc.sh
./camera_i2c_config
first,it will config IO pin. Then you can run cs_mipi_i2c.sh.
2.1 camera_i2c_config USAGE
- for standard RPI, just run
./camera_i2c_config
- for RPI Computer Module
./camera_i2c_config [cameranum]

3 cs_mipi_i2c.sh USAGE
./cs_mipi_i2c.sh
this shell scripts should be used for CS-MIPI-IMX307!
Usage: ./cs_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2 -p3 param3 -b bus
options:
-r read
-w write
-f [function name] function name
-p1 [param1] param1 of each function
-p2 [param1] param2 of each function
-p3 [param1] param3 of each function
-b [i2c bus num] i2c bus number
-d [i2c addr] i2c addr if not default 0x3b
support functions: devid,hdver,camcap,firmwarever,productmodel,videofmtcap,videofmt,ispcap,i2caddr,streammode,powerhz,sysreset,paramsave
Pi3B / Pi3B+ / 3A / 4B(1G/2G/4G),we use i2c0
Compute Module/ CM3,we use i2c1,please add -b 1 option.
3.1 devid
./cs_mipi_i2c.sh -r -f devid
0x02 | 2 lan mipi |
3.2 hdver
./veye_mipi_i2c.sh -r -f hdver
get hardware logic version
value | description |
---|---|
0xXY | Version X.Y |
for example:
0x22 means V2.2
3.3 firmwarever
./cs_mipi_i2c.sh -r -f firmwarever
get firmware version, X.Y, 1.0 for example.
3.4 productmodel
./cs_mipi_i2c.sh -r -f productmodel
get product model,for example:CS-MIPI-IMX307
3.5 camcap
./cs_mipi_i2c.sh -r -f camcap
get camera module capbility, each bit represents a function.

---|---|
0 | sync stream mode |
3.6 videofmtcap
./cs_mipi_i2c.sh -r -f videofmtcap
get camera video format capbility, for example:
1920*1080 30fps
1280*720 60fps
3.7 videofmt
./cs_mipi_i2c.sh -r -f videofmt
./cs_mipi_i2c.sh -w -f videofmt -p1 1920 -p2 1080 -p3 30
./cs_mipi_i2c.sh -w -f videofmt -p1 1280 -p2 720 -p3 60
./cs_mipi_i2c.sh -w -f videofmt -p1 640 -p2 480 -p3 130
get and set current video format,for example:
1920*1080@30fps
1280*720@60fps
640*480@130fps
3.8 ispcap
./cs_mipi_i2c.sh -r -f ispcap
get camera isp capbility. Will add details later.
3.9 powerhz
./cs_mipi_i2c.sh -r -f powerhz
./cs_mipi_i2c.sh -w -f powerhz -p1 50
./cs_mipi_i2c.sh -w -f powerhz -p1 60
value | description |
---|---|
50 | Power frequency is 50Hz |
60 | Power frequency is 60Hz |
Configure the power frequency of the environment in which the camera is used.
- 50Hz framerate is 25、50、100;60Hz framerate is 30、60、120.
- camera support antiflicker, accroding to powerhz setting here.
3.10 i2caddr
./cs_mipi_i2c.sh -r -f i2caddr -d i2caddrnow
./cs_mipi_i2c.sh -w -f i2caddr -p1 newi2caddr -d oldi2caddr
This module support i2c addr change by software, i2c addr range[0x3,0x77].
Note: only supported on firmware version >= 1.05
3.11 paramsave
./cs_mipi_i2c.sh -w -f paramsave
Write the configured parameters to flash. So parameters will not be lost when poweroff.
3.12 sysreset
./cs_mipi_i2c.sh -w -f sysreset
The camera reset to the factory default parameters.
3.13 streammode
value | description |
---|---|
0 | free running |
1 | sync mode |
value | description |
---|---|
0 | master |
1 | slave |
./cs_mipi_i2c.sh -r -f streammode
Read the current stream mode and master-slave mode
./cs_mipi_i2c.sh -w -f streammode -p1 0
Set the current camera to free running mode
./cs_mipi_i2c.sh -w -f streammode -p1 1 -p2 0
Set the current camera to sync mode, and set to master
./cs_mipi_i2c.sh -w -f streammode -p1 1 -p2 1
Set the current camera to sync mode, and set to slave
sync mode :Camera module Stream Mode manual
Note: only supported on camcap bit 0 is 1.
