^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) The ISL29003 is an integrated light sensor with a 16-bit integrating type
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) ADC, I2C user programmable lux range select for optimized counts/lux, and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) I2C multi-function control and monitoring capabilities. The internal ADC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) artificial light sources.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The driver allows to set the lux range, the bit resolution, the operational
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) mode (see below) and the power state of device and can read the current lux
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) value, of course.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) The ISL29003 does not have an ID register which could be used to identify
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) it, so the detection routine will just try to read from the configured I2C
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) address and consider the device to be present as soon as it ACKs the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) transfer.
