| + | ====Raspberry Pi 3==== | ||
| + | The Raspberry Pi is a very small computer that has the characteristics of the computers people would use 15 years ago. | ||
| + | Raspberry Pi 3 characteristics: | ||
| + | * Broadcom BCM2837 SoC (4 ARM Cortex-A53); | ||
| + | * GB of RAM; | ||
| + | * integrated WiFi and BLE; | ||
| + | * HDMI port, an Ethernet port and four USB ports; | ||
| + | * several pins to use for electronics: | ||
| + | * two 5V pins; | ||
| + | * two 3.3V pins; | ||
| + | * 8 ground pins; | ||
| + | * 26 data pins; | ||
| + | * 1 PWM pin. | ||
| + | {{ :iot:labs:raspberry_pi3.png?500 |}} | ||
| + | The Raspberry Pi 3 has 26 GPIO soldered pins and 5 GPIO pins that you need to solder. These may be used to control electronics connected to the Raspberry Pi. Among the things that can be done are: | ||
| + | *light up LEDs; | ||
| + | *place buttons; | ||
| + | *use relays; | ||
| + | *control motors. | ||
| - | Let's see what you can do with your Intel® Edison board. | + | It is important to know how these pins can be accessed. For the Raspberry Pi, Wyliodrin uses the WiringPi pins layout described below. |
| + | {{ :iot:labs:pins-raspberrypi.png?700 |Raspberry Pi 3 Pins Layout}} | ||
| - | Intel® Edison is a tiny computer that allows you to easily create the Internet of Things projects you always dreamed of. | + | ====Wyliodrin STUDIO==== |
| - | It aims at enabling beginners, students, teachers, makers and any technology enthusiast to ease their everyday lives by using systems they've built themselves. | + | |
| - | The Intel® Edison was designed with wearable devices in mind. Its small dimensions and the integrated Wi-Fi and Bluetooth make it a great component for any wearable device. | + | Wyliodrin STUDIO is a web-based platform for Internet of Things applications development. You are going to use this platform throughout the course for programming and controlling the Raspberry Pi. |
| - | The next depicts the emplacement and the numbering of the pins on the Intel® Edison breakout board. | + | |
| - | {{ :iot:labs:edison_pins.png?300 |{{:iot:labs:edison_pins.png?300|}}}} | + | |
| - | The Edison can be connected to an expansion board that gives you the possibility to access up to 40 pins. What is important to know is that the board itself has no ADC, however the expansion board does and they are connected via the SPI pins. Thus with the help of the expansion board you can create a system that actively interacts with its environment. | + | In order to connect the Raspberry Pi to Wyliodrin STUDIO you will need an SD Card with minimum 4 GB (class 10 is recommended). You also need to assure the Raspberry Pi has a network connection or a serial connection to your computer (Ethernet or serial cable). |
| - | The board consists of a dual-core Intel® Atom CPU and 32-bit Intel® Quark™ micro-controller. | + | Setting up the board requires the following steps: |
| - | ==== Key features of Intel® Edison ==== | + | *Install Wyliodrin STUDIO; |
| - | Key features of Intel® Edison: | + | *Download the Raspberry Pi SD Card Image; |
| - | - an Intel® SoC that includes a dual-core, dual-threaded Intel® Atom CPU at 500 MHz and a 32-bit Intel® Quark micro-controller at 100 MHz | + | *Write the image to an SD Card; |
| - | - 1 GB RAM memory | + | *Connect the board to your computer; |
| - | - Integrated Wi-Fi Broadcom 43340 802.11 a/b/g/n | + | *Connect the board to Wyliodrin STUDIO |
| - | - Integrated Bluetooth 4.0 | + | |
| - | - Programmable through the Arduino integrated development environment (IDE) that is supported on Microsoft Windows*, Mac OS*, and Linux host operating systems, Intel® XDK, Eclipse and //Wyliodrin//. | + | |
| - | - Support for Yocto 1.6. | + | |
| - | ====Wyliodrin Setup}==== | + | |
| - | {{:iot:labs:edison.png?300|}} | + | |
| - | In order to setup your Wyliodrin account and connect your board, please go to https://wyliodrin.cs.pub.ro/. | + | |
| - | Sign in with one of your Facebook, Google or GitHub accounts. After signing in, right at the top of the projects page you will find the //Add new board// button. Please press the button and continue below to add the embedded board to your account. | + | |
| - | Afterwards, depending on the board you are connecting, you have to follow some different steps. | + | ===Install Wyliodrin STUDIO=== |
| - | - Flash the Edison | + | Go to [[http://wyliodrin.studio|Wyliodrin STUDIO]]. There are two ways you can use WyliodrinSTUDIO, one is to download the application and the other one is to use it in the browser. |
| - | - Download the board configuration file and write it to the Edison | + | |
| - | - Download the install script file and write it to the Edison | + | |
| - | - Copy configuration file | + | |
| - | - Run updates | + | |
| - | ==== Flash the Edison ==== | + | |
| - | To flash the Edison board you just need to follow //Step 1// and //Step 2// in the instructions on Intel's website. You will have to choose the Operating System that runs on the computer you are going to connect the Edison to. | + | |
| - | ==== Board activation ==== | + | |
| - | Copy the file //wyliodrin.json// on it. Make sure the file is named exactly //wyliodrin.json//. | + | |
| - | Copy the install script ((https://www.wyliodrin.com/public/scripts/install_edison.sh)) on it. Make sure it is named exactly //install_ edison.sh// | + | |
| - | {{ :iot:labs:files-list-edison.jpg?300 |}} | + | ===Set up the Raspberry Pi=== |
| - | Connect the USB to the Edison so that you see the console. Run **configure_edison --setup **. | + | In Wyliodrin STUDIO so to **Menu** and select **Documentation**. Choose Raspberry Pi and follow the steps.Connect the Raspberry Pi to the network via the Ethernet cable, then connect it to the platform. The default username is **pi** and the default password is **raspberry**. |
| - | This will configure the name of the board and WiFi. | + | |
| - | Please make sure that your WiFi is sending IP addresses in a network different than 192.168.2.0/24. | + | |
| - | To install Wyliodrin, run \\ | + | |
| - | ** mkdir /media/storage **\\ | + | |
| - | ** mount -o loop,ro,offset=8192 /dev/mmcblk0p9 /media/storage **\\ | + | |
| - | ** cd /media/storage **\\ | + | |
| - | ** sh install_edison.sh **\\ | + | |
| - | In a few moments you should see the board online. | + | |
| - | A full tutorial on how to setup your board is available online. ((https://projects.wyliodrin.com/wiki/boards_setup/inteledison))\\ | + | Once the board is connected double click its name and give it a more suggestive name so you can recognize it. Then, go to **network manager** and set the WiFi credentials. |
| - | You can watch a tutorial on how to add a new board online. ((https://www.youtube.com/watch?v=HHzWRNAYY40&list=PLHih6DnKQaoaMTyPOzn6-MaNppf4VoaRr&index=1)) | + | |
| - | === Connect an already flashed board === | + | |
| - | If your Intel® Edison is already flashed, all you need to do is to copy the wyliodrin.json file onto the board. | + | |
| - | Wire up the Intel® Edison to your computer in the same way as described in //Flash the Edison//. Make sure you use the USB adapter closer to the power. You should see a disk called Edison. | + | So you make sure nobody connects to your board, open the **Shell** tab and type **passwd**. Set another password for the user **pi**. |
| - | Copy the file //wyliodrin.json// on it. Make sure the file is named exactly //wyliodrin.json//. | + | Disconnect the board from the Ethernet cable and now you will be able to connect to it via WiFi. |
| - | Unplug all the cables form the board and plug them back. | + | ====Exercises==== |
| - | + | - Create a new Python application that prints your name in the console. | |
| - | Your board should get online. | + | - Load the **Music** example application, connect a speaker or headphones to the Raspberry Pi and make it sing. |
| + | - Install **Math.Pi** using the **package manager**. | ||
| + | - Create a Python application that prints your name every one second. | ||
| + | - Run the previously created application. Using the **task manager** identify the corresponding task and kill it. | ||
