adiam 0:526e53f544a8 2 # Blinky Mbed OS example
adiam 0:526e53f544a8 3
adiam 0:526e53f544a8 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/).
adiam 0:526e53f544a8 5
adiam 0:526e53f544a8 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).
adiam 0:526e53f544a8 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).)
adiam 0:526e53f544a8 8
adiam 0:526e53f544a8 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
adiam 0:526e53f544a8 10
adiam 0:526e53f544a8 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
adiam 0:526e53f544a8 12
adiam 0:526e53f544a8 13 ```bash
adiam 0:526e53f544a8 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
adiam 0:526e53f544a8 15 ```
adiam 0:526e53f544a8 16
adiam 0:526e53f544a8 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
adiam 0:526e53f544a8 18
adiam 0:526e53f544a8 19 ```bash
adiam 0:526e53f544a8 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
adiam 0:526e53f544a8 21 ```

adiam 0:526e53f544a8 23
adiam 0:526e53f544a8 24 ## Application functionality
adiam 0:526e53f544a8 25
adiam 0:526e53f544a8 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.

adiam 0:526e53f544a8 28 ## Building and running
adiam 0:526e53f544a8 29
adiam 0:526e53f544a8 30 1. Connect a USB cable between the USB port on the board and the host computer.
adiam 0:526e53f544a8 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
adiam 0:526e53f544a8 32 ```bash
adiam 0:526e53f544a8 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
adiam 0:526e53f544a8 34 ```
adiam 0:526e53f544a8 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
adiam 0:526e53f544a8 36
adiam 0:526e53f544a8 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
adiam 0:526e53f544a8 38
adiam 0:526e53f544a8 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:
adiam 0:526e53f544a8 40
adiam 0:526e53f544a8 41 ```bash
adiam 0:526e53f544a8 42 $ mbed compile -S
adiam 0:526e53f544a8 43 ```
adiam 0:526e53f544a8 44
adiam 0:526e53f544a8 45 ## Expected output
adiam 0:526e53f544a8 46 The LED on your target turns on and off every 500 milliseconds.
adiam 0:526e53f544a8 47
adiam 0:526e53f544a8 48
adiam 0:526e53f544a8 49 ## Troubleshooting
adiam 0:526e53f544a8 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.
