Raspberry Pi Python i2c library for the ADXL3453-axis MEMS accelerometer IC which is used in breakout boards like the Adafruit ADXL345 Triple-Axis Accelerometer (http://shop.pimoroni.com/products/adafruit-triple-axis-accelerometer).
This library is a basic implementation of the i2c protocol for the IC offering a simple way to get started with it on the Raspberry Pi.
You can import the module and get a sensor reading like this:
from adxl345 import ADXL345
adxl345 = ADXL345()
axes = adxl345.getAxes(True)
print("ADXL345 on address 0x%x:" % (adxl345.address))
print(" x = %.3fG" % ( axes['x'] ))
print(" y = %.3fG" % ( axes['y'] ))
print(" z = %.3fG" % ( axes['z'] ))
or you can run it directly from the command line like this:
python3 adxl345.py
which will output the current x, y, and z axis readings in Gs.
