# Apache Blinky

## Overview

Apache Blinky is a skeleton for new Apache Mynewt projects.  The user downloads
this skeleton by issuing the "newt new" command (using Apache Newt).  Apache
Blinky also contains an example app and target for use with Apache Mynewt to
help you get started.

## Building

Apache Blinky contains an example Apache Mynewt application called blinky.
When executed on suitably equipped hardware, this application repeatedly blinks
an LED.  The below procedure describes how to build this application for the
Apache Mynewt simulator.

1. Download and install Apache Newt.

You will need to download the Apache Newt tool, as documented in the [Getting Started Guide](https://mynewt.apache.org/latest/get_started/index.html).

2. Download the Apache Mynewt Core package (executed from the blinky directory).

```no-highlight
    $ newt upgrade
```

3. Build the blinky app for the sim platform using the "my_blinky_sim" target
(executed from the blinky directory).

```no-highlight
    $ newt build my_blinky_sim
```

The Apache Newt tool should indicate the location of the generated blinky
executable.  Since the simulator does not have an LED to blink, this version of
blinky is not terribly exciting - a printed message indicating the current LED
state.  To learn how to build blinky for actual hardware, please see the
[Getting Started Guide](https://mynewt.apache.org/latest/get_started/index.html).
