mv_mipi_i2c.sh Shell scripts usage
1 Overview
The mv_mipi_i2c.sh script is a tool set for configuring MV MIPI series cameras through the I2C.
This script is essentially an access to registers. For registers, please refer to MV Series and RAW Series MIPI Camera Register Map.
2 Raspberry Pi on Legacy mode Only, Set IO config
Note that if you are using v4l2 mode, you do not need to perform this step.
Running
./enable_i2c_vc.sh
./camera_i2c_config
first,it will config IO pin. Then you can run mv_mipi_i2c.sh.

8 Functions list
8.1 Note
The camera has two states, standby and running, after the start of image acquisition into the running state.
There are some registers that are write-protected in the running state, which will be marked with an asterisk. For example: trgsrc* .
There are some parameters that have strict range restrictions, and it's a good idea to try reading them when you're in doubt.
8.2 Basic Parameters
8.2.1 manufacturer
./mv_mipi_i2c.sh -r -f manufacturer -b your_i2c_bus_number
Get the manufacturer name, which is VEYE.
8.2.2 model
./mv_mipi_i2c.sh -r -f model -b your_i2c_bus_number
Get the product model, such as MV-MIPI-IMX178M / MV-MIPI-SC132M.
8.2.3 version
./mv_mipi_i2c.sh -r -f version -b your_i2c_bus_number
Get the Controller version number and Logical version number.
The system has two main control chips that serve the control and logic functions respectively.
8.2.4 serialno
./mv_mipi_i2c.sh -r -f serialno -b your_i2c_bus_number
Get the unique serial number of this module.
8.2.5 timestamp
./mv_mipi_i2c.sh -r -f timestamp -b your_i2c_bus_number
Time after system startup in Milliseconds.
This value starts counting again if you call the reboot command, or if the camera reboots unexpectedly.
8.2.6 errcode
./mv_mipi_i2c.sh -r -f errcode -b your_i2c_bus_number

8.5 Image Features
8.5.1 maxwh
./mv_mipi_i2c.sh -r -f maxwh -b your_i2c_bus_number
Get the maximum supported resolution of the sensor.
8.5.2 maxfps
./mv_mipi_i2c.sh -r -f maxfps -b your_i2c_bus_number
The maximum frame rate supported in the current mode.
Depending on the configured ROI, the maximum frame rate will be different. This parameter supports decimals.
8.5.3 fps*
./mv_mipi_i2c.sh -w -f fps -p1 [framerate] -b your_i2c_bus_number
./mv_mipi_i2c.sh -r -f fps -b your_i2c_bus_number
Configure the actual frame rate of the camera in the current mode.
Range:(0,maxfps].
In video streaming mode, this parameter determines the actual frame rate.
In normal trigger mode, it is recommended to set the fps to the maxfps value to ensure the highest trigger signal responsiveness.
8.5.4 roi*
./mv_mipi_i2c.sh -w -f roi -p1 [x] -p2 [y] -p3 [width] -p4 [height] -b your_i2c_bus_number
./mv_mipi_i2c.sh -r -f roi -b your_i2c_bus_number
ROI(region of interest) is the sensor output area, and the default is full screen output.
Parameter requirements:
[x] [y] [height] must be 4-aligned;
[width] must be 8-aligned;
The minimum ROI resolution will be different for different sensors.
For example, MV-MIPI-IMX178M minimum resolution is: 376*320;MV-MIPI-SC130M minimum resolution is 64*64.
The camera will make necessary adjustments to the user parameters to meet the parameter requirements.

9 Configuration Method for Typical Application Scenarios:
9.1 Manual Exposure Mode:
./mv_mipi_i2c.sh -w -f expmode -p1 0 -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f gainmode -p1 0 -b your_i2c_bus_number

./mv_mipi_i2c.sh -w -f mgain -p1 gain_you_want_to_set_dB -b your_i2c_bus_number
After configuration, read the parameters with the following commands to confirm they have taken effect:
./mv_mipi_i2c.sh -r -f exptime -b your_i2c_bus_number
./mv_mipi_i2c.sh -r -f curgain -b your_i2c_bus_number
Note: The maximum exposure time must be strictly less than the reciprocal of the fps.
9.2 Continuous Auto Exposure Mode:
./mv_mipi_i2c.sh -w -f expmode -p1 2 -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f gainmode -p1 2 -b your_i2c_bus_number

./mv_mipi_i2c.sh -w -f aemaxtime -p1 [16,1000000/fps] -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f agmaxgain -p1 [0,maxgain] -b your_i2c_bus_number
After continuous imaging for a while, you can read the current actual exposure time and gain using the following commands:
./mv_mipi_i2c.sh -r -f exptime -b your_i2c_bus_number
./mv_mipi_i2c.sh -r -f curgain -b your_i2c_bus_number
9.3 Normal Trigger Mode:
First, stop the image acquisition to enter a state where the trigger mode can be modified:
./mv_mipi_i2c.sh -w -f imgacq -p1 0 -b your_i2c_bus_number
In the following example, configure the camera for normal hardware trigger mode, where each trigger signal captures 1 image:
./mv_mipi_i2c.sh -w -f trgmode -p1 1 -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f trgsrc -p1 1 -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f trgnum -p1 1 -b your_i2c_bus_number
You may optionally execute the following two commands to set the trigger edge and delay:
./mv_mipi_i2c.sh -w -f trgedge -p1 [0,1] -b your_i2c_bus_number
./mv_mipi_i2c.sh -w -f trgdelay -p1 [us] -b your_i2c_bus_number
After configuration, you can start the image acquisition to accept trigger signals:
./mv_mipi_i2c.sh -w -f imgacq -p1 1 -b your_i2c_bus_number
