What: /sys/bus/iio/devices/triggerX/trigger_polarity
KernelVersion: 4.11
Contact: fabrice.gasnier@st.com
Description:
The STM32 ADC can be configured to use external trigger sources
(e.g. timers, pwm or exti gpio). Then, it can be tuned to start
conversions on external trigger by either:
- "rising-edge"
- "falling-edge"
- "both-edges".
Reading returns current trigger polarity.
Writing value before enabling conversions sets trigger polarity.
