Introduction

The OIS driver plugin is used to control the LC898122AXA OIS module. It provides control for quite a few features of the OIS module. These features are explained in this user guide.
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 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.

OIS Driver Features

Initialize OIS Driver Button – Click this to initialize the OIS module.

Calibration Data

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.

OIS Control

There are two modes of OIS control, automatic and manual.
Manual Control
The default is manual control. It exposes two sliders, one for X direction, and other for Y direction. Slide these to see the lens moving in X and Y direction respectively. The hall sensor values can also be accessed by clicking the "Read values" button. The range for this data is -0.4 to + 0.4.
Auto OIS
This enables the OIS module in the LC898122. User can select movie mode or still mode using the radio buttons.

Focus control

This plugin provides manual focus control. There are two types of VCM drive supported with the LC898122 module, i.e. differential and single ended. Select the appropriate value. Please note that this re-initializes the OIS module. You have to reload Calibration data, if you are not using the default values.
After selecting the VCM drive, control the lens position with the slider.

Test Gyro

This plugin also provides a way to test the Gyro. Click this button to run the test. The status will show up below.
