7 Functions list
7.1 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.

./gx_mipi_i2c.sh -w drc [0,255] -b your_i2c_bus_number
Digital wide dynamic range. Range [0-255], 0 indicates off.
7.6 IO Control
7.6.1 trgdelay
./gx_mipi_i2c.sh -r trgdelay -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgdelay [0,1000000] -b your_i2c_bus_number
Trigger delay, effective under both soft trigger and hard trigger mode.
range: 0 to 1000000 (unit: microsecond)
7.6.2 trgedge
./gx_mipi_i2c.sh -r trgedge -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgedge [0,1] -b your_i2c_bus_number
Effective trigger edge in hard trigger mode.
| value | description |
|---|---|
| 0 | Rising edge |
| 1 | Falling edge |
7.6.3 trgexp_delay
./gx_mipi_i2c.sh -r trgexp_delay -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgexp_delay [0,100000] -b your_i2c_bus_number
Exposure delay, i.e. the time to turn on the Strobe signal in advance.
range: 0 to 1000000 (unit: microsecond)
The difference between trgexp_delay and trgdelay, see manual for details.
7.6.4 outio1_rvs
./gx_mipi_i2c.sh -r outio1_rvs -b your_i2c_bus_number
./gx_mipi_i2c.sh -w outio1_rvs [0,1] -b your_i2c_bus_number
Reverse OUT_IO1 high and low levels if set to 1.
8 Notes
Note1: All parameters of exposure time are in microseconds. However, due to the properties of the sensor, the actual exposure time unit of the sensor is 1 line, can not be accurate to 1us.
9 Configuration Method for Typical Application Scenarios:
9.1 Stream mode:
./gx_mipi_i2c.sh -w imgacq 1 -b your_i2c_bus_number
9.2 Trigger mode:
./gx_mipi_i2c.sh -w imgacq 0 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w workmode 1 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgsrc 0 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgnum 1 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trginterval 0 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w trgone -b your_i2c_bus_number
According to the above command, you can take a picture.
9.3 Sync mode:
Note: The synchronous mode requires two cameras.
./gx_mipi_i2c.sh -w slavemode 0 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w slavemode 1 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w workmode 4 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w workmode 4 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w imgacq 1 -b your_i2c_bus_number
./gx_mipi_i2c.sh -w imgacq 1 -b your_i2c_bus_number
./veye_raspipreview -cs 1 -p '0,0,1000,520' -t -1
./veye_raspipreview -cs 0 -p '600,0,1280,720' -t -1
After completing the above configuration, you can proceed to start capturing images.
Please note that if you need to adjust the frame rate during the image acquisition process, you must first stop the acquisition before making the changes.
After stopping the acquisition, the camera will still complete the capture of the current frame.
The newly set parameters will only take effect afterward.
