Python library for using a LIS3DH triple-axis accelerometer on a Raspberry Pi

python-lis3dh's Issues

Does not work with new restructed libs from Adafruit

Hi Matt,

great work! It helped me a lot!

But unfortunately there are small issues with the new restructured gpio/i2c libs from Adafruit.

There were 3 changes required to get it working for me:
in file LIS3DH.py:
a) line15: The import must be changed from from Adafruit_I2C import Adafruit_I2C to import Adafruid_GPIO.I2C as I2C
b) line 94: further the instanciaton from self.i2c = Adafruit_I2C(address, busnum=bus) to self.i2c = I2C.Device(address, busnum=bus)

in file testLIS3DH.py
c) line 16: the init of the sensor object need the bus number: sensor = LIS3DH(debug=True) to sensor = LIS3DH(bus=1,debug=True)

Thank you!
Best Regards

Michael

Implement 'click' functionality

The LIS3DH allows for the 'interrupt' (INT) pin to be set high according to a set of given parameters, functionality to set and make use of this is not currently exposed in this library.

Example C code here

Implement ADC reading

The LIS3DH has 3 analogue-to-digital converters on board. Currently these are not exposed through this library.

The datasheet section 8.2 refers, example C code here

Deprecated?

Adafruit has deprecated the Adafruit_Python_GPIO library (see https://github.com/adafruit/Adafruit_Python_GPIO) in favour of 'blinka' (https://github.com/adafruit/Adafruit_Blinka), which allows to use their full-fledged CircuitPython code for the sensor (https://github.com/adafruit/Adafruit_CircuitPython_LIS3DH).

The blinka library is exclusively for Python 3, so if you need a Python 2 compatible library for the sensor, this library here might still be useful. (I recently switched to using the CircuitPython library and it works perfectly.)

I want to thank @mattdy for providing this, it helped me a lot in the past few years!
