Y is the 7 specific stage number corresponding to datasheet stage names 8 as follows: 9 10 == ========== 11 1 LED2 12 2 ALED2/LED3 13 3 LED1 14 4 ALED1/LED4 15 == ========== 16 17 Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1 18 respectively which simply helper channels containing the 19 calculated difference in the value of stage 1 - 2 and 3 - 4. 20 The values are expressed in 24-bit twos complement. 21 The LED current for the stage is controlled via 22 out_currentY_raw. 23 24What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_offset 25Date: May 2016 26KernelVersion: 27Contact: Andrew F.
