Description:
Reading returns the list possible quadrature modes.
What: /sys/bus/iio/devices/iio:deviceX/in_count0_quadrature_mode
KernelVersion: 4.12
Contact: benjamin.gaignard@st.com
Description:
Configure the device counter quadrature modes:
channel_A:
Encoder A input servers as the count input and B as
the UP/DOWN direction control input.
channel_B:
Encoder B input serves as the count input and A as
the UP/DOWN direction control input.
quadrature:
Encoder A and B inputs are mixed to get direction
and count with a scale of 0.25.
