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,firmwarever,productmodel,videofmtcap,videofmt,ispcap,i2caddr,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
| value | description |
|---|---|
| 0x210 | CS-MIPI-IMX307 |
3.2 firmwarever
./cs_mipi_i2c.sh -r -f firmwarever
get firmware version, X.Y, 1.0 for example.
3.3 productmodel
./cs_mipi_i2c.sh -r -f productmodel
get product model，for example：CS-MIPI-IMX307
3.4 videofmtcap
./cs_mipi_i2c.sh -r -f videofmtcap
get camera video format capbility, for example:
1920*1080 30fps
1280*720 60fps
3.5 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
get and set current video format，for example:
1920*1080 30fps
1280*720 60fps
3.6 ispcap
./cs_mipi_i2c.sh -r -f ispcap
get camera isp capbility. Will add details later.
3.7 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.
3.8 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].
3.9 paramsave
./cs_mipi_i2c.sh -w -f paramsave
Write the configured parameters to flash. So parameters will not be lost when poweroff.
3.10 sysreset
./cs_mipi_i2c.sh -w -f sysreset
The camera reset to the factory default parameters.
