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_accelerometer
        accel_x, accel_y, accel_z = sensor.accelerometer
        raw_mag_x, raw_mag_y, raw_mag_z = sensor.raw_magnetometer
        mag_x, mag_y, mag_z = sensor.magnetometer

        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('')
        time.sleep(1.0)

Building locally¶

To build this library locally you’ll need to install the circuitpython-build-tools package.

python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools

Once installed, make sure you are in the virtual environment:

source .env/bin/activate

Then run the build:

circuitpython-build-bundles --filename_prefix adafruit-circuitpython-lsm303 --library_location .
