What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_raw Date: May 2016 KernelVersion: Contact: Andrew F. Davis 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 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/in_intensityY_resistance What: /sys/bus/iio/devices/iio:deviceX/in_intensityY_capacitance Date: May 2016 KernelVersion: Contact: Andrew F. Davis Description: Get and set the resistance and the capacitance settings for the Transimpedance Amplifier during the associated stage. What: /sys/bus/iio/devices/iio:deviceX/out_currentY_raw Date: May 2016 KernelVersion: Contact: Andrew F. Davis Description: Get and set the LED current for the specified LED active during this stage. Y is the specific stage number.
