- Kernel driver isl29003
- =====================
- Supported chips:
- * Intersil ISL29003
- Prefix: 'isl29003'
- Addresses scanned: none
- Datasheet:

- Author: Daniel Mack <daniel@caiaq.de>
- Description
- -----------
- The ISL29003 is an integrated light sensor with a 16-bit integrating type
- ADC, I2C user programmable lux range select for optimized counts/lux, and
- I2C multi-function control and monitoring capabilities. The internal ADC
- provides 16-bit resolution while rejecting 50Hz and 60Hz flicker caused by
- artificial light sources.
- The driver allows to set the lux range, the bit resolution, the operational
- mode (see below) and the power state of device and can read the current lux
- value, of course.
- Detection
- ---------
- The ISL29003 does not have an ID register which could be used to identify
- it, so the detection routine will just try to read from the configured I2C
- address and consider the device to be present as soon as it ACKs the
- transfer.
- Sysfs entries
- -------------
- range:
- 0: 0 lux to 1000 lux (default)
- 1: 0 lux to 4000 lux
- 2: 0 lux to 16,000 lux
- 3: 0 lux to 64,000 lux
- resolution:
- 0: 2^16 cycles (default)
- 1: 2^12 cycles
- 2: 2^8 cycles
- 3: 2^4 cycles
- mode:
- 0: diode1's current (unsigned 16bit) (default)
- 1: diode1's current (unsigned 16bit)
- 2: difference between diodes (l1 - l2, signed 15bit)
- power_state:
- 0: device is disabled (default)
- 1: device is enabled
- lux (read only):
- returns the value from the last sensor reading
