description: |
|
||||
STMicroelectronics LSM9DS1 9-axis IMU (Inertial Measurement Unit) sensor
|
||||
accessed through I2C bus.
|
||||
|
||||
This binding describe only the inertial part : accelerometer and gyroscope.
|
||||
|
||||
When setting the accel-range, gyro-range, imu-odr properties in
|
||||
a .dts or .dtsi file you may include lsm9ds1.h and use the macros
|
||||
defined there.
|
||||
|
||||
Example:
|
||||
#include <zephyr/dt-bindings/sensor/lsm9ds1.h>
|
||||
|
||||
lsm9ds1: lsm9ds1@0 {
|
||||
...
|
||||
|
||||
accel-range = <LSM9DS1_DT_FS_4G>;
|
||||
imu-odr = <LSM9DS1_IMU_14Hz9>;
|
||||
gyro-range = <LSM9DS1_DT_FS_2000DPS>;
|
||||
};
|
||||
|
||||
compatible: "st,lsm9ds1"
|
||||
|
||||
include: [sensor-device.yaml, i2c-device.yaml]
