thomasheck 0:c635b2c93ead 2 # Blinky Mbed OS example
thomasheck 0:c635b2c93ead 3
thomasheck 0:c635b2c93ead 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/).
thomasheck 0:c635b2c93ead 5
thomasheck 0:c635b2c93ead 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).

thomasheck 0:c635b2c93ead 8
thomasheck 0:c635b2c93ead 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
thomasheck 0:c635b2c93ead 10
thomasheck 0:c635b2c93ead 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
thomasheck 0:c635b2c93ead 12
thomasheck 0:c635b2c93ead 13 ```bash
thomasheck 0:c635b2c93ead 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
thomasheck 0:c635b2c93ead 15 ```
thomasheck 0:c635b2c93ead 16
thomasheck 0:c635b2c93ead 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
thomasheck 0:c635b2c93ead 18
thomasheck 0:c635b2c93ead 19 ```bash
thomasheck 0:c635b2c93ead 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
thomasheck 0:c635b2c93ead 21 ```

thomasheck 0:c635b2c93ead 25
thomasheck 0:c635b2c93ead 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.

thomasheck 0:c635b2c93ead 28 ## Building and running
thomasheck 0:c635b2c93ead 29
thomasheck 0:c635b2c93ead 30 1. Connect a USB cable between the USB port on the board and the host computer.
thomasheck 0:c635b2c93ead 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
thomasheck 0:c635b2c93ead 32 ```bash
thomasheck 0:c635b2c93ead 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
thomasheck 0:c635b2c93ead 34 ```
thomasheck 0:c635b2c93ead 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
thomasheck 0:c635b2c93ead 36
thomasheck 0:c635b2c93ead 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
thomasheck 0:c635b2c93ead 38
thomasheck 0:c635b2c93ead 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:
thomasheck 0:c635b2c93ead 40
thomasheck 0:c635b2c93ead 41 ```bash
thomasheck 0:c635b2c93ead 42 $ mbed compile -S
thomasheck 0:c635b2c93ead 43 ```
thomasheck 0:c635b2c93ead 44
thomasheck 0:c635b2c93ead 45 ## Expected output
thomasheck 0:c635b2c93ead 46 The LED on your target turns on and off every 500 milliseconds.
