rescudev 0:490fae09419d 2 # Blinky Mbed OS example
rescudev 0:490fae09419d 3
rescudev 0:490fae09419d 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/).
rescudev 0:490fae09419d 5
rescudev 0:490fae09419d 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).
rescudev 0:490fae09419d 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).)
rescudev 0:490fae09419d 8
rescudev 0:490fae09419d 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
rescudev 0:490fae09419d 10
rescudev 0:490fae09419d 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
rescudev 0:490fae09419d 12
rescudev 0:490fae09419d 13 ```bash
rescudev 0:490fae09419d 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
rescudev 0:490fae09419d 15 ```
rescudev 0:490fae09419d 16
rescudev 0:490fae09419d 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
rescudev 0:490fae09419d 18
rescudev 0:490fae09419d 19 ```bash
rescudev 0:490fae09419d 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
rescudev 0:490fae09419d 21 ```

rescudev 0:490fae09419d 24 ## Application functionality
rescudev 0:490fae09419d 25
rescudev 0:490fae09419d 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.
rescudev 0:490fae09419d 27
rescudev 0:490fae09419d 28 ## Building and running
rescudev 0:490fae09419d 29
rescudev 0:490fae09419d 30 1. Connect a USB cable between the USB port on the board and the host computer.
rescudev 0:490fae09419d 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
rescudev 0:490fae09419d 32 ```bash
rescudev 0:490fae09419d 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
rescudev 0:490fae09419d 34 ```
rescudev 0:490fae09419d 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
rescudev 0:490fae09419d 36
rescudev 0:490fae09419d 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
rescudev 0:490fae09419d 38
rescudev 0:490fae09419d 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:
rescudev 0:490fae09419d 40
rescudev 0:490fae09419d 41 ```bash
rescudev 0:490fae09419d 42 $ mbed compile -S
rescudev 0:490fae09419d 43 ```
rescudev 0:490fae09419d 44
rescudev 0:490fae09419d 45 ## Expected output
rescudev 0:490fae09419d 46 The LED on your target turns on and off every 500 milliseconds.
rescudev 0:490fae09419d 47
rescudev 0:490fae09419d 48
rescudev 0:490fae09419d 49 ## Troubleshooting
rescudev 0:490fae09419d 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.
