The OIS driver plugin is used to control the LC898122AXA OIS module. It provides control for quite a few all the features of the OIS module. These features are explained in this user guidedetail below.
Note: This module has been enabled with the AR2520 and the AR1335 sensors so far. If your sensor is not supported, this plugin will not show up in the Plug-ins menu. To add new sensors, please contact the dev team.
To Start the OIS Driver plugin, start :
- Start DevWare/DevWareX application and load the sensor data file for the sensor.
- Load the INI preset required, and get the sensor to stream.
- Then go
...
- to Plug-ins->OIS Driver.
The following window comes up.

The EEPROM is used to store the Calibration data. The user can enter the EEPROM slave address and start address from which to load the EEPROM data. It is assumed that the EEPROM data is stored in the following format. If the format of the calibration data stored in the EEPROM changes, please contact the dev team.

Slave Address – Enter the slave address of the EEPROM.
Start Address – Enter the start address at which the contents are stored. The first 4 bytes must be the pattern mentioned above, if the EEPROM data is valid.
Load Calibration Data Button – Click this button after entering the Slave and Start addresses, to load calibration data from the EEPROM to the OIS module.
...
This plugin also provides a way to test the Gyro. Click this button to run the test. The status will show up below.
