agat 0:cf20365296f5 2 # Blinky Mbed OS example
agat 0:cf20365296f5 3
agat 0:cf20365296f5 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/).
agat 0:cf20365296f5 5
agat 0:cf20365296f5 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).
agat 0:cf20365296f5 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).)
agat 0:cf20365296f5 8
agat 0:cf20365296f5 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
agat 0:cf20365296f5 10
agat 0:cf20365296f5 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
agat 0:cf20365296f5 12
agat 0:cf20365296f5 13 ```bash
agat 0:cf20365296f5 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
agat 0:cf20365296f5 15 ```
agat 0:cf20365296f5 16
agat 0:cf20365296f5 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
agat 0:cf20365296f5 18
agat 0:cf20365296f5 19 ```bash
agat 0:cf20365296f5 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
agat 0:cf20365296f5 21 ```

agat 0:cf20365296f5 24 ## Application functionality
agat 0:cf20365296f5 25
agat 0:cf20365296f5 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.

agat 0:cf20365296f5 28 ## Building and running
agat 0:cf20365296f5 29
agat 0:cf20365296f5 30 1. Connect a USB cable between the USB port on the board and the host computer.
agat 0:cf20365296f5 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
agat 0:cf20365296f5 32 ```bash
agat 0:cf20365296f5 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
agat 0:cf20365296f5 34 ```
agat 0:cf20365296f5 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
agat 0:cf20365296f5 36
agat 0:cf20365296f5 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
agat 0:cf20365296f5 38
agat 0:cf20365296f5 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:
agat 0:cf20365296f5 40
agat 0:cf20365296f5 41 ```bash
agat 0:cf20365296f5 42 $ mbed compile -S
agat 0:cf20365296f5 43 ```
agat 0:cf20365296f5 44
agat 0:cf20365296f5 45 ## Expected output
agat 0:cf20365296f5 46 The LED on your target turns on and off every 500 milliseconds.
agat 0:cf20365296f5 47
agat 0:cf20365296f5 48
agat 0:cf20365296f5 49 ## Troubleshooting
agat 0:cf20365296f5 50 If you have problems, you can review the [documentation](https://os.mbed.com/docs/latest/tutorials/debugging.html) for suggestions on what could be wrong and how to fix it.
