| 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] |
