| <h2 id="blinky-your-hello-world-on-a-target-board">Blinky, your "Hello World!" on a Target Board</h2> |
| <p>The set of Blinky tutorials show you how to create, build, and run a "Hello World" application that blinks a LED on the various target boards that Mynewt supports. The tutorials use the same Blinky application from the <a href="/os/get_started/project_create">Creating Your First Project</a> tutorial. </p> |
| <h3 id="objective">Objective</h3> |
| <p>Learn how to use packages from a default application repository of Mynewt to build your first <em>Hello World</em> application (Blinky) on a target board. Once built using the <em>newt</em> tool, this application will blink a LED light on the target board.</p> |
| <h3 id="available-tutorials">Available Tutorials</h3> |
| <p>Tutorials are available for the following boards:</p> |
| <ul> |
| <li><a href="/os/tutorials/arduino_zero.md">Blinky on an Arduino Zero</a></li> |
| <li><a href="/os/tutorials/blinky_primo.md">Blinky on an Arduino Primo</a></li> |
| <li><a href="/os/tutorials/olimex.md">Blinky on an Olimex</a></li> |
| <li><a href="/os/tutorials/nRF52.md">Blinky on a nRF52 Development Kit</a></li> |
| <li><a href="/os/tutorials/rbnano2.md">Blinky on a RedBear Nano 2</a></li> |
| <li><a href="/os/tutorials/blinky_stm32f4disc.md">Blinky on a STM32F4-Discovery</a></li> |
| </ul> |
| <p>We also have a tutorial that shows you how to add <a href="/os/tutorials/blinky_console.md">Console and Shell to the Blinky Application</a>. |
| <br></p> |
| <h3 id="prerequisites">Prerequisites</h3> |
| <p>Ensure that you meet the following prerequisites before continuing with one of the tutorials. </p> |
| <ul> |
| <li>Have Internet connectivity to fetch remote Mynewt components.</li> |
| <li>Have a computer to build a Mynewt application and connect to the board over USB.</li> |
| <li>Have a Micro-USB cable to connect the board and the computer.</li> |
| <li>Install the newt tool and toolchains (See <a href="/os/get_started/get_started.md">Basic Setup</a>).</li> |
| <li>Read the Mynewt OS <a href="/os/get_started/vocabulary.md">Concepts</a> section. </li> |
| <li>Create a project space (directory structure) and populate it with the core code repository (apache-mynewt-core) or know how to as explained in <a href="/os/get_started/project_create">Creating Your First Project</a>. |
| <br></li> |
| </ul> |
| <h3 id="overview-of-steps">Overview of Steps</h3> |
| <p>These are the general steps to create, load and run the Blinky application on your board:</p> |
| <ul> |
| <li>Create a project.</li> |
| <li>Define the bootloader and Blinky application targets for the board.</li> |
| <li>Build the bootloader target.</li> |
| <li>Build the Blinky application target and create an application image.</li> |
| <li>Connect to the board.</li> |
| <li>Load the bootloader onto the board.</li> |
| <li>Load the Blinky application image onto the board.</li> |
| <li>See the LED on your board blink.</li> |
| </ul> |
| <p><br></p> |
| <p>After you try the Blinky application on your boards, checkout out other tutorials to enable additional functionality such as <a href="../project-slinky/">remote comms</a> on the current board. If you have BLE (Bluetooth Low Energy) chip (e.g. nRF52) on your board, you can try turning it into an <a href="../ibeacon/">iBeacon</a> or <a href="../eddystone/">Eddystone Beacon</a>! </p> |
