LSM6DS3TR-C MicroPython Library

The LSM6DS3TR-C is an always-on 3D accelerometer and 3D gyroscope that includes additional built-in functions such as:

• Pedometer
• Tap and double tap recognition
• Significant motion and tilt detection
• Free-fall detection

Example Program

An example showing the basic setup and reading of the Gyro and Accelerometer.

from machine import I2C
from lsm6ds3 import LSM6DS3, NORMAL_MODE_104HZ
import time

i2c = I2C(0, scl=13, sda=12)
sensor = LSM6DS3(i2c, mode=NORMAL_MODE_104HZ)

while True:
    ax, ay, az, gx, gy, gz = sensor.get_readings()
    print("Accelerometer\nX:{}, Y:{}, Z:{}\nGyro\nX:{}, Y:{}, Z{}\n\n ".format(ax, ay, az, gx, gy, gz))
    time.sleep(1.0)

Functions

.get_readings()

Get the current X Y Z values from the Accelerometer and Gyro. Returns ax ay az gx gy gz

Output:

>>> sensor.get_readings()
(-5839, -5124, -10199, 192, 12030, 24831)

.get_step_count()

Get the current number of steps detected by the sensor. Returns an integer value.

Output:

>>> sensor.get_step_count()
29

.reset_step_count()

Reset the step counter to 0

.tilt_detected()

Returns 1 if the sensor detects tilt on the X Y or Z axis and 0 if no tilt detected.

.sig_motion_detected()

Returns 1 if the sensor detects significant motion and 0 if no significant motion detected.

.single_tap_detected()

Returns 1 if the sensor detects a single tap on the X Y or Z axis and 0 if no tap detected.

.double_tap_detected()

Returns 1 if the sensor detects a double tap on the X Y or Z axis and 0 if no double tap detected.

.freefall_detected()

Returns 1 if the sensor detects it is currently in free fall and 0 if no free fall detected.
