ISL29035: Digital Light Sensor
|
|
##############################
|
|
|
|
Overview
|
|
********
|
|
|
|
If trigger is not enabled the sample displays measured light intensity
|
|
every 2 seconds.
|
|
|
|
If trigger is enabled the sample displays light intensity from the
|
|
ISL29035 sensor every 10 seconds if it is within +/- 50 lux of the last
|
|
read sample. If the sensor detects an intensity outside that range the
|
|
application wakes, displays the intensity, resets the intensity range
|
|
window to center on the new value, then continues as before.
|
|
|
|
Requirements
|
|
************
|
|
|
|
This sample uses an external breakout for the sensor. A devicetree
|
|
overlay must be provided to connect the sensor to the I2C bus and
|
|
identify the interrupt signal.
