What is MATRIX HAL?
HAL or Hardware Abstraction Layer is the lowest level layer of the MATRIX Creator drivers. You can either interact directly with HAL, or use the higher level components like MALOS or the MATRIX OS to tinker with the MATRIX Device. This uses C++ drivers for available sensors and hardware.
Things Needed
Raspberry Pi
Matrix Device
Micro SD Card
Active Internet Connection
A Power Adapter ( Min 2.3 Amp)
Camera (Optional)
Step 1 : Setting Up Raspberry Pi
Download and burn latest Raspbian image to a micro SD card and insert it into the raspberry Pi.
Now power it up with a power adapter that can provide at least 2.5 Ampere. Now fire up your terminal and create a password for the user ‘pi’ by executing the command
sudo passwd pi
Connect your Raspberry Pi to a WiFi router or Wired network and make sure it is connected by checking whether it is getting an IP address from the switch.
Now perform and update and upgrade by running
sudo apt update -ysudo apt upgrade -y
Step 2 : Connect MATRIX Device to Raspberry Pi
Now simply align the header pins and slowly connect the MATRIX device to your Raspberry Pi
Step 3 : Adding the key and repository
curl https://apt.matrix.one/doc/apt-key.gpg | sudo apt-key add - echo "deb https://apt.matrix.one/raspbian $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/matrixlabs.list
Step 4 : Perform Update and Upgrade
sudo apt-get update sudo apt-get upgrade
Step 5 : Installing the MATRIX Software
sudo apt-get install matrixio-creator-init sudo reboot
Step 6 : Setting Up HAL
Install Required Packages
sudo apt-get install git cmake g++ libfftw3-dev wiringpi libgflags-dev
Step 7 : Download HAL
git clone https://github.com/matrix-io/matrix-creator-hal.git
Step 8 : Build
cd matrix-creator-hal/ mkdir build cd build/ cmake .. make -j4
Running the Demos
Now from the build folder, go to the folder demo
cd demos/
From there, you can choose any demo script and run it
./arc_demo
./mic_energy
