For my latest project (details coming soon available here) I acquired a couple of LIS3DH triple-axis accelerometers. As most of the products available through Adafruit are fairly well used, I didn’t bother checking what libraries were available before buying, but unfortunately for me only a C++ library had been written. I didn’t feel like learning C just for the purpose of this project, and so the only option left was to write my own Python library!
Thankfully I had some excellent starting points with the aforementioned C++ library, as well as the Python I2C library that Adafruit have published. I found myself referring back to the manufacturer datasheet quite often as well, mainly to clarify what each register contained.
While the task initially looked rather daunting (having had zero prior experience with bit-bashing through registers) – I found that with some pre-existing code to crib from, the various functions took shape rather quickly, and within an afternoon I’d produced a library exposing all the basic functions I’m likely to need for this project. I’ve put my code on Github in the hope that people will contribute to filling in the gaps, and improving where necessary.
