ADC/DAC mode

Using the Dell Command | Configure application, you can switch GPIO to ADC (Analog-to-Digital Converter) or DAC (Digital-to-Analog Converter) mode. For more information, see the Dell Command | Configure Version 3.3 Command Line Interface Reference Guide at www.dell.com/support.

After switching to ADC or DAC mode, use the AD5593R IIO DAC/ADC Linux Driver to access ADC/DAC pins as described at wiki.analog.com/resources/tools-software/linux-drivers/iio-dac/ad5593r#driver_testing
NOTE: System reboot is required to apply changes.
Access the ADC/DAC pins through IIO. For example: 
/sys/bus/iio/devices/devices/iio:device0
/sys/bus/iio/devices/devices/iio:device1
