Introduction¶
Adafruit CircuitPython module for the LSM303 6-DoF with 3-axis accelerometer and magnetometer
Dependencies¶
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Usage Example¶
import time
import board
import busio
import adafruit_lsm303
i2c = busio.I2C(board.SCL, board.SDA)
sensor = adafruit_lsm303.LSM303(i2c)
while True:
raw_accel_x, raw_accel_y, raw_accel_z = sensor.raw_acceleration
accel_x, accel_y, accel_z = sensor.acceleration
raw_mag_x, raw_mag_y, raw_mag_z = sensor.raw_magnetic
mag_x, mag_y, mag_z = sensor.magnetic
print('Acceleration raw: ({0:6d}, {1:6d}, {2:6d}), (m/s^2): ({3:10.3f}, {4:10.3f}, {5:10.3f})'.format(raw_accel_x, raw_accel_y, raw_accel_z, accel_x, accel_y, accel_z))
print('Magnetometer raw: ({0:6d}, {1:6d}, {2:6d}), (gauss): ({3:10.3f}, {4:10.3f}, {5:10.3f})'.format(raw_mag_x, raw_mag_y, raw_mag_z, mag_x, mag_y, mag_z))
print('')
