MC3419 3-axis accel sensor
|
|
|
|
Example:
|
|
#include <zephyr/dt-bindings/sensor/mc3419.h>
|
|
|
|
mc3419: mc3419@0 {
|
|
...
|

|
|
lpf-fc-sel = <MC3419_LPF_DISABLE>;
|
|
decimation-rate = <MC3419_DECIMATE_IDR_BY_1>;
|
|
};
|
|
|
|
compatible: "memsic,mc3419"
|
|
|
|
include: [sensor-device.yaml, i2c-device.yaml]
|
|

|
This property specifies the connection for INT, this pin
|
|
defaults to active low when sample produce interrupt.
|
|
|
|
int-pin2:
|
|
type: boolean
|
|
description: |
|
|
This property is used for interrupt routing.The sensor
|
|
has two interrupt pins.By default the interrupt are routed
|
|
to interrupt pin 1, by enabled this property interrupt are
|
|
routed to interrupt pin 2.
