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

Running

./enable_i2c_vc.sh

./camera_i2c_config

first,it will config IO pin. Then you can run mv_mipi_i2c.sh.

3 Prepare

cd mv_tools_rpi/sources/

./make.sh

cd ..

chmod +x *

4 mv_mipi_i2c.sh USAGE

./mv_mipi_i2c.sh

Usage:  ./mv_mipi_i2c.sh [-r/w] [-f] function name -p1 param1 -p2 param2 -b bus

options:

    -r                       read

    -w                       write

6 Functions list

6.1 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.

6.2 Basic Parameters

6.2.1 manufacturer

./mv_mipi_i2c.sh -r -f manufacturer -b your_i2c_bus_number

Get the manufacturer name, which is VEYE.

6.2.2 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.

6.2.3 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.

6.2.4 serialno

./mv_mipi_i2c.sh -r -f serialno -b your_i2c_bus_number

Get the unique serial number of this module.

6.2.5 timestamp

./mv_mipi_i2c.sh -r -f timestamp -b your_i2c_bus_number

This value starts counting again if you call the reboot command, or if the camera reboots unexpectedly.

6.2.6 errcode

./mv_mipi_i2c.sh -r -f errcode -b your_i2c_bus_number

System error code, each bit represents an error type.

bit0: sensor error.

bit1: Logic module startup error.

bit2: Logic module communication error.

bit5: AA(AE&AG) regulation cannot reach the target brightness.

bit6: Authorization failure.

6.2.7 fmtcap

./mv_mipi_i2c.sh -r -f fmtcap -b your_i2c_bus_number

Capbility of data formats supported by the camera.

bit0: Mono8

6.2.8 factoryparam

./mv_mipi_i2c.sh -w -f factoryparam -b your_i2c_bus_number

All parameters restored to factory default values.

6.2.9 paramsave

./mv_mipi_i2c.sh -w -f paramsave -b your_i2c_bus_number

Save all parameters to flash, and they will not be lost when power off.

6.2.10 reboot

./mv_mipi_i2c.sh -w -f reboot -b your_i2c_bus_number

Reboot the camera.

6.2.11 i2caddr

./mv_mipi_i2c.sh -w -f i2caddr -p1 [new] -b your_i2c_bus_number

./mv_mipi_i2c.sh -r -f slavemode -b your_i2c_bus_number

Whether the sensor is operating in slave mode. In slave mode, the camera relies on external signals to provide XVS and XHS.

Writing this parameter will cause the camera to automatically save the current settings and reboot.

Currently, only RAW-MIPI-IMX462M support this function.

6.2.13 mcubypass

6.5 Image Features

6.5.1 maxwh

./mv_mipi_i2c.sh -r -f maxwh -b your_i2c_bus_number

Get the maximum supported resolution of the sensor.

6.5.2 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.

6.5.3 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.

6.5.4 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.

So it is highly recommended that you read out the actual ROI parameters after writing them.

6.5.5 imgdir

./mv_mipi_i2c.sh -w -f imgdir -p1 [0,3] -b your_i2c_bus_number

./mv_mipi_i2c.sh -r -f imgdir -b your_i2c_bus_number

value description
0 normal
1 mirror
2 flip
3 flip&mirror

The image is first flipped/mirrored and then ROI cropped. For details, please refer to the manual.

6.5.6 pixelformat

./mv_mipi_i2c.sh -w -f pixelformat -p1 [0,2] -b your_i2c_bus_number

./mv_mipi_i2c.sh -r -f pixelformat -b your_i2c_bus_number

value description
0 Mono8
1 Mono10
2 Mono12
4 UYVY

Note that for the MV-MIPI-IMX178M, the AD bits of the sensor is always 12 bits, and the logic unit performs data rounding to achieve a different pixel format.

6.5.7 blacklevel

  2. Run AE once and AG once.
  3. Wait 5 seconds.
  4. Check AE once and AG once result.

Read the sensor's register indirectly via the camera controller unit.

6.7 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.

Note2: AE: Auto exposure; AG: Auto Gain; AA: AE and AG.

Note3: The AAROI coordinates are relative coordinates within the ROI area.

Note4: For RAW Series, there are some functions that are not supported, please refer to the register list for details.
