MicroPython-LIS3DH

MicroPython library for the LIS3DH IMU

This is the IMU IC used on the TinyPICO Play shield.

Currently under development

Proper interrupt support

Example usage

import lis3dh
from machine import Pin, I2C

i2c = I2C(sda=Pin(21), scl=Pin(22)) # Correct I2C pins for TinyPICO
imu = lis3dh.LIS3DH_I2C(i2c)

# If we have found the LIS3DH
if imu.device_check():
    # Set range of accelerometer (can be RANGE_2_G, RANGE_4_G, RANGE_8_G or RANGE_16_G).
    imu.range = lis3dh.RANGE_2_G

    # Loop forever printing accelerometer values
    while True:
        # Read accelerometer values (in m / s ^ 2).  Returns a 3-tuple of x, y,
        # z axis values.  Divide them by 9.806 to convert to Gs.
        x, y, z = [value / lis3dh.STANDARD_GRAVITY for value in imu.acceleration]
        print("x = %0.3f G, y = %0.3f G, z = %0.3f G" % (x, y, z))
        # Small delay to keep things responsive but give time for interrupt processing.
        time.sleep(0.1)
        ```
