mbed_official 102:6979ad8bc0bc 2 # Blinky Mbed OS example
Jonathan Austin 0:2757d7abb7d9 3
mbed_official 102:6979ad8bc0bc 4 The example project is part of the [Arm Mbed OS Official Examples](https://os.mbed.com/code/) and is the [getting started example for Mbed OS](https://os.mbed.com/docs/mbed-os/v5.14/quick-start/index.html). It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/).
Jonathan Austin 0:2757d7abb7d9 5
mbed_official 102:6979ad8bc0bc 6 You can build the project with all supported [Mbed OS build tools](https://os.mbed.com/docs/mbed-os/latest/tools/index.html). However, this example project specifically refers to the command-line interface tool [Arm Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
mbed_official 102:6979ad8bc0bc 7 (Note: To see a rendered example you can import into the Arm Online Compiler, please see our [import quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)
mbed_official 82:abf1b1785bd7 8
mbed_official 102:6979ad8bc0bc 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
mbed_official 82:abf1b1785bd7 10
mbed_official 102:6979ad8bc0bc 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
mbed_official 102:6979ad8bc0bc 12
mbed_official 102:6979ad8bc0bc 13 ```bash
mbed_official 102:6979ad8bc0bc 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
mbed_official 102:6979ad8bc0bc 15 ```
mbed_official 82:abf1b1785bd7 16
mbed_official 102:6979ad8bc0bc 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
mbed_official 82:abf1b1785bd7 18
mbed_official 102:6979ad8bc0bc 19 ```bash
mbed_official 102:6979ad8bc0bc 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
mbed_official 102:6979ad8bc0bc 21 ```

mbed_official 102:6979ad8bc0bc 24 ## Application functionality
mbed_official 82:abf1b1785bd7 25
mbed_official 102:6979ad8bc0bc 26 The `main()` function is the single thread in the application. It toggles the state of a digital output connected to an LED on the board.

mbed_official 102:6979ad8bc0bc 28 ## Building and running
mbed_official 102:6979ad8bc0bc 29
mbed_official 102:6979ad8bc0bc 30 1. Connect a USB cable between the USB port on the board and the host computer.
mbed_official 102:6979ad8bc0bc 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
mbed_official 102:6979ad8bc0bc 32 ```bash
mbed_official 102:6979ad8bc0bc 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
mbed_official 102:6979ad8bc0bc 34 ```
mbed_official 102:6979ad8bc0bc 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
mbed_official 102:6979ad8bc0bc 36
mbed_official 102:6979ad8bc0bc 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
mbed_official 102:6979ad8bc0bc 38
mbed_official 102:6979ad8bc0bc 39 Depending on the target, you can build the example project with the `GCC_ARM`, `ARM` or `IAR` toolchain. After installing Arm Mbed CLI, run the command below to determine which toolchain supports your target:
mbed_official 102:6979ad8bc0bc 40
mbed_official 103:681967d62a72 41 ```bash
mbed_official 103:681967d62a72 42 $ mbed compile -S
mbed_official 103:681967d62a72 43 ```
mbed_official 102:6979ad8bc0bc 44
mbed_official 102:6979ad8bc0bc 45 ## Expected output
mbed_official 102:6979ad8bc0bc 46 The LED on your target turns on and off every 500 milliseconds.
