What: /sys/bus/iio/devices/iio:deviceX/tia_resistanceY
/sys/bus/iio/devices/iio:deviceX/tia_capacitanceY
Date: December 2015
KernelVersion:
Contact: Andrew F. Davis <afd@ti.com>
Description:
Get and set the resistance and the capacitance settings for the
Transimpedance Amplifier. Y is 1 for Rf1 and Cf1, Y is 2 for
Rf2 and Cf2 values.
What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_raw
Date: May 2016
KernelVersion:
Contact: Andrew F. Davis <afd@ti.com>
Description:
Get measured values from the ADC for these stages. Y is the
specific stage number corresponding to datasheet stage names
as follows:
1 -> LED2
2 -> ALED2/LED3
3 -> LED1
4 -> ALED1/LED4
Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
respectively which simply helper channels containing the
calculated difference in the value of stage 1 - 2 and 3 - 4.
The values are expressed in 24-bit twos complement.
What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_offset
Date: May 2016
KernelVersion:
Contact: Andrew F. Davis <afd@ti.com>
Description:
Get and set the offset cancellation DAC setting for these
stages. The values are expressed in 5-bit sign-magnitude.
What: /sys/bus/iio/devices/iio:deviceX/out_currentY_raw
Date: May 2016
KernelVersion:
Contact: Andrew F. Davis <afd@ti.com>
Description:
Get and set the LED current for the specified LED active during
this stage. Y is the specific stage number.
