LSM6DSL: IMU sensor Monitor

Overview

This sample sets the LSM6DSL accelerometer and gyroscope to 104Hz and enable a trigger on data ready. It displays on the console the values for accelerometer and gyroscope, plus optionally the values of any magnetometer or pressure sensor attached to it (sensorhub function).

Requirements

This sample uses the LSM6DSL sensor controlled using the I2C or SPI interface. It has been tested on both 96Boards Argonkey and disco_l475_iot1 board.

Building and Running

This project outputs sensor data to the console. It requires an LSM6DSL sensor, which is present on both the 96Boards Argonkey and disco_l475_iot1 board.

Building on ArgonKey board

cd $ZEPHYR_BASE/samples/sensors/lsm6dsl
mkdir build && cd build
cmake -GNinja -DBOARD=96b_argonkey ..
ninja

Building on disco_l475_iot1 board

cd $ZEPHYR_BASE/samples/sensors/lsm6dsl
mkdir build && cd build
cmake -GNinja -DBOARD=disco_l475_iot1 ..
ninja

Sample Output

LSM6DSL sensor samples:

accel (-3.184000 -0.697000 9.207000) m/s2
gyro (0.065000 -0.029000 0.002000) dps
magn (-0.042000 0.294000 -0.408000) gauss
- (0) (trig_cnt: 190474)

<repeats endlessly every 2 seconds>

Note

The magn row is displayed only when running sample onto 96b_argonkey board, where a magnetometer is connected to LSM6DSL.
