Analog inputs (ADC)

Overview

Many of our products have analog inputs. On the MX-4 platform they are accessible under /opt/hm/pic_attributes/ (see below). Otherwise we use the standard Linux Industrial I/O Subsystem. You can then access the ADC from sysfs, typically /sys/bus/iio/devices/iio\:device*/.

Platform specific

• MX-4
  • MX-4 T30/T30fr
  • C61 IO
  • CT
• MX-V

Example

IIO

cat /sys/bus/iio/devices/iio:device0/*DIG_IN_AN_8_raw

MX-4

cat /opt/hm/pic_attributes/analog_1
