HAL is the lowest-level abstraction for the MATRIX Creator drivers. You can interface directly with HAL, or use the higher level components like MALOS, and the MATRIX OS itself.
It does have some package dependencies, so please make sure to install the pre-requisites.
$ sudo apt-get install cmake g++ git libfftw3-dev
To start working with HAL directly, you'll need to run sudo make install to get the build running.
$ mkdir build
$ cd build
$ cmake ..
$ make && sudo make install
