Raspberry Pi 3B
USB cable
Ethernet cable

What you need to know

Raspberry Pi is a low-cost general-purpose computing platform, running on a Debian-based Linux operating system. It can be also configured as an embedded system incorporating sensors, and programmed through MATLAB/Simulink. Raspberry Pi board is comprised of 1.2GHz Broadcom 64bit CPU and 1GB RAM, with in-built WiFi and Bluetooth Low Energy.

What you need to do

Frist step -Setup Board

Download the OS from the official website, in this post we chose Raspbian OS.
Burn the OS image to the SD card. You could use Win32DiskImager tool to do this job.
Setup the Raspberry Pi Raspbian OS to be compatible with MATLAB and Simulink support package for Raspberry Pi. Copy the Shell script corresponding to your Raspbian version to the Raspberry Pi hardware from there and run the shell script on the Raspberry Pi terminal.
Test the connection between MATLAB and Raspberry Pi, on the MATLAB command prompt, execute the following

myrpi = raspi('Device IP address','Username','password')
% Device IP adress - IP address of your raspberry pi
% Username - Username associated with the login on Raspberry Pi
% Password  - Corresponding password

After execution, if the command returns a valid Raspi object, the setup for Raspberry Pi is successful.

Second step-Run First Alogrithm

myrpi = raspi('Device IP address', 'Username', 'passward');
witeLED (myrpi, 'led0', 1);   % Switch on led0
witeLED (myrpi, 'led0,  0);     % Switch off led0

The above code will instruct the board to switch on or off led0. You can make the LED bink in a loop with a period of 1 second as well:

for i = 1:10
  writeLED(rpi, led, 0);
  pause(0.5);
  writeLED(rpi, led, 1);
  pause(0.5);
end

Third step- Interact witch Raspberry Pi Board

openShell(myrpi)

A terminal window will appear and you can execute Linux commands there. Then you can interaci by the session with the berry Pi board.

Forth step-Shutdown the board

There is no a shutdown button on the board so the correct procedure is not to unplug the power cable. Instead, you shall execute the shutdown instruction in either the MATLAB command window or the terminal session. The following MATLAB command will shut down the system in one minute

system(myrpi, 'sudo shutdown -h');

Alternatively, you can enter the Linux command in the terminal session.

sudo shutdown -h

Finally , I hope you enjoy playing Raspberry Pi!!
