# About
This is a manual test application for the ISL29020 light sensor driver.
# Usage
This test application will initialize the list sensor with the following parameters:
- Mode: Ambient light measurement
- Range: 16000LUX
After initialization, the sensor value is read every 250ms and printed to the STDOUT.
To verify the seen value you can hold the sensor into a bright light or shield the sensor to
see the value changing.
