Calibration Procedure
This chapter illustrates the calibration steps of LG69T (AA) EVB, and the calibration process is based on
the premise that the user has fixed the EVB. No displacement or rotation of the EVB should occur after
calibration, as described in the following chapters.
The calibration process needs to be repeated only in the following cases:
⚫
The EVB has been moved and reinstalled.
⚫
During a DR cold start and when the NVM is blank or invalid.
⚫
Please strictly follow the steps in
Chapter
to complete the angle calibration process, because any
improper operation may affect the calibration.
