The A pin to use.
For pins P0.0 through P0.31, use the pin number. For example,
to use P0.16 for the A pin, set:
a-pin = <16>;
For pins P1.0 through P1.31, add 32 to the pin number. For
example, to use P1.2 for the A pin, set:
a-pin = <34>; /* 32 + 2 */
This property is required. |
|
|
The B pin to use. The pin numbering scheme is the same as
the a-pin property's.
This property is required. |
|
|
The LED pin to use for a light based QDEC device. The pin
numbering scheme is the same as the a-pin property's.
|
|
|
The enable pin to use, to enable a connected QDEC device. The
pin numbering scheme is the same as the a-pin property's.

|
Time LED is enabled prior to sampling event (in us)
This property is required. |
|
|
Number of steps on the rotating wheel
This property is required. |
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “nordic,nrf-qdec” compatible.
