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.

개요
Trigger를 활성화하지 않으면 sample은 측정한 light intensity를 2초마다 표시합니다.
Trigger를 활성화하면 마지막으로 읽은 sample을 중심으로 ±50 lux 범위 안에 있는 동안 ISL29035 light intensity를 10초마다 표시합니다. Sensor가 이 범위를 벗어난 intensity를 감지하면 application이 깨어나 값을 표시하고, 새 값을 중심으로 intensity range window를 다시 설정한 뒤 이전과 같은 동작을 계속합니다.
요구 사항
이 sample은 외부 sensor breakout을 사용합니다. Sensor를 I2C bus에 연결하고 interrupt signal을 식별하는 Devicetree overlay를 제공해야 합니다.

<repeats as necessary>ALERT는 조도가 현재 ±50 lux window를 벗어났음을 뜻합니다. 이어지는 Next alert outside가 새 중심값을 기준으로 계산한 다음 interrupt 범위를 보여 주며, 필요한 만큼 측정과 범위 재설정을 반복합니다.
