Davis <afd@ti.com> 6Description: 7 Get and set the resistance and the capacitance settings for the 8 Transimpedance Amplifier. Y is 1 for Rf1 and Cf1, Y is 2 for 9 Rf2 and Cf2 values. 10 11What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_raw 12Date: May 2016 13KernelVersion: 14Contact: Andrew F. Davis <afd@ti.com> 15Description: 16 Get measured values from the ADC for these stages. Y is the 17 specific stage number corresponding to datasheet stage names 18 as follows: 19 1 -> LED2 20 2 -> ALED2/LED3 21 3 -> LED1 22 4 -> ALED1/LED4 23 Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1 24 respectively which simply helper channels containing the 25 calculated difference in the value of stage 1 - 2 and 3 - 4. 26 The values are expressed in 24-bit twos complement. 27 28What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_offset 29Date: May 2016 30KernelVersion: 31Contact: Andrew F.
