thegecko 0:103bac868627 105 ## What Blinky does
thegecko 0:103bac868627 106
thegecko 0:103bac868627 107 This is a short review of the Blinky code. More information is available on the user guide, where we explain [how to write mbed OS applications](https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/Full_Guide/app_on_mbed_os/) and how to [work with yotta](https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/Full_Guide/app_on_yotta/).
thegecko 0:103bac868627 108
thegecko 0:103bac868627 109 1. The code begins with ``include``. The included header is ``mbed.h``, from the ``mbed-drivers`` library. It is a key library for mbed OS, and includes most of the functionality standard applications need. yotta, our build system, includes ``mbed-drivers`` during compilation because that library is listed as a dependency in Blinky's ``module.json`` file.
thegecko 0:103bac868627 110
thegecko 0:103bac868627 111 1. mbed OS applications start with ``app_start``, replacing ``main``.
thegecko 0:103bac868627 112
thegecko 0:103bac868627 113 1. MINAR is the mbed OS scheduler; we use it here to create a callback that will run every 500 milliseconds. The function we're running is ``blinky``.
thegecko 0:103bac868627 114
thegecko 0:103bac868627 115 1. ``blinky`` creates a DigitalOut using the LED1 on our board. It then turns the LED on and off and prints its status to the terminal using ``printf``.

thegecko 0:103bac868627 118 **Tip:** To learn more about writing applications for mbed OS, see the [mbed OS user guide's review of Blinky](https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/Full_Guide/app_on_mbed_os/).

thegecko 0:103bac868627 123 ### If you're using yotta as a command-line tool
thegecko 0:103bac868627 124
thegecko 0:103bac868627 125 **Tip:** If you need help setting up yotta or building a project, see our [quick guide](https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/FirstProjectmbedOS/), which uses the same example.
thegecko 0:103bac868627 126
thegecko 0:103bac868627 127 To build Blinky with yotta as a command-line tool:
thegecko 0:103bac868627 128
thegecko 0:103bac868627 129 1. Clone the repository from GitHub:
thegecko 0:103bac868627 130
thegecko 0:103bac868627 131 ```
thegecko 0:103bac868627 132 $ git clone https://github.com/ARMmbed/example-mbedos-blinky.git
thegecko 0:103bac868627 133 $ cd example-mbedos-blinky
thegecko 0:103bac868627 134 ```
thegecko 0:103bac868627 135
thegecko 0:103bac868627 136 2. Select a target platform:
thegecko 0:103bac868627 137
thegecko 0:103bac868627 138 ```
thegecko 0:103bac868627 139 $ yotta target frdm-k64f-gcc
thegecko 0:103bac868627 140 ```
thegecko 0:103bac868627 141
thegecko 0:103bac868627 142 3. Build it:
thegecko 0:103bac868627 143
thegecko 0:103bac868627 144 ```
thegecko 0:103bac868627 145 $ yotta build
thegecko 0:103bac868627 146 ... bunch of build messages ...
thegecko 0:103bac868627 147 [135/135] Linking CXX executable source/example-mbedos-blinky
thegecko 0:103bac868627 148 ```
thegecko 0:103bac868627 149
thegecko 0:103bac868627 150 yotta will put the compiled binary in the project's `/build` folder. Copy the binary `/build/frdm-k64f-gcc/source/example-mbedos-blinky.bin` to your mbed board over USB.

thegecko 0:103bac868627 152 ### If you're on the online IDE
thegecko 0:103bac868627 153
thegecko 0:103bac868627 154 **Tip:** If you need help getting started with the IDE, see our [quick guide](https://docs.mbed.com/docs/getting-started-mbed-os/en/latest/FirstProjectmbedOS/), which uses the same example.
thegecko 0:103bac868627 155
thegecko 0:103bac868627 156 To build Blinky in your IDE workspace:
thegecko 0:103bac868627 157
thegecko 0:103bac868627 158 1. The IDE needs to know which target to build for. Click *Target*:
thegecko 0:103bac868627 159
thegecko 0:103bac868627 160 1. The list displays your recently used targets. If the target you need is listed, click it.

thegecko 0:103bac868627 162 1. If your target isn't in the drop-down list, click *Search in Registry*. A list of targets opens. Select your target and click *Set*.
thegecko 0:103bac868627 163
thegecko 0:103bac868627 164 1. Click *Build Project*.
thegecko 0:103bac868627 165
thegecko 0:103bac868627 166 The IDE will build the project as a binary file and ask you to download it. When the download finishes, copy the file to your mbed board over USB.
