EVM is covered. The green LED on the EVM hardware indicates power, and the red LED indicates if
an interrupt event has occurred. The LEDs will be enabled at the start of the utility and can be turned
on/off as an application preference from this menu item.
The
Main

item. This feature is useful for studying the lux-to-nits relationship for a particular LCD panel. This
feature can be accessed from the menu. Simply enable logging and select the interval at which to log
the data.
The firmware version of the EVM is noted in the lower right hand corner on the status bar.
