SCA3300-D01 3-axis Industrial Accelerometer and Inclinometer with Digital SPI Interface Library

This repository contains a minimal driver to use Murata SCA3300-D01 3-axis device.

Information

First of all this library is really light. The code is probbaly not perfect but works. Feel free to fork it :)

This project is based on Meson/Ninja build system
More information Menson/Ninja : http://mesonbuild.com/

You will find 3 sub folders.
Once contains the library, once an Hello World and the last one some unit tests.

As the project is base on Meson you can find configuration files as:
Master Meson file
Binary Meson file
Librairie Meson file

Build

Native compilation

[nicolas:sca3300]% mkdir build && meson build

Cross compilation ( for Raspberry pi 3 )

[nicolas:lib]% mkdir buildcross
[nicolas:lib]% meson buildcross --cross-file cross_file.txt

Note: As with Make you have access to the clean command:

[nicolas:lib]% ninja -C buildcross clean
ninja: Entering directory `buildcross'
[1/1] 'Cleaning'

Build static library and example binary

[nicolas:lib]% ninja -C buildcross
