1stefikefi 0:5a7b9ea14056 2 # Blinky Mbed OS example
1stefikefi 0:5a7b9ea14056 3
1stefikefi 0:5a7b9ea14056 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/).
1stefikefi 0:5a7b9ea14056 5
1stefikefi 0:5a7b9ea14056 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).
1stefikefi 0:5a7b9ea14056 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).)
1stefikefi 0:5a7b9ea14056 8
1stefikefi 0:5a7b9ea14056 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
1stefikefi 0:5a7b9ea14056 10
1stefikefi 0:5a7b9ea14056 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
1stefikefi 0:5a7b9ea14056 12
1stefikefi 0:5a7b9ea14056 13 ```bash
1stefikefi 0:5a7b9ea14056 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
1stefikefi 0:5a7b9ea14056 15 ```
1stefikefi 0:5a7b9ea14056 16
1stefikefi 0:5a7b9ea14056 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
1stefikefi 0:5a7b9ea14056 18
1stefikefi 0:5a7b9ea14056 19 ```bash
1stefikefi 0:5a7b9ea14056 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
1stefikefi 0:5a7b9ea14056 21 ```
1stefikefi 0:5a7b9ea14056 22
1stefikefi 0:5a7b9ea14056 23
1stefikefi 0:5a7b9ea14056 24 ## Application functionality
1stefikefi 0:5a7b9ea14056 25
1stefikefi 0:5a7b9ea14056 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.
1stefikefi 0:5a7b9ea14056 27
1stefikefi 0:5a7b9ea14056 28 ## Building and running
1stefikefi 0:5a7b9ea14056 29
1stefikefi 0:5a7b9ea14056 30 1. Connect a USB cable between the USB port on the board and the host computer.
1stefikefi 0:5a7b9ea14056 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
1stefikefi 0:5a7b9ea14056 32 ```bash
1stefikefi 0:5a7b9ea14056 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
1stefikefi 0:5a7b9ea14056 34 ```
1stefikefi 0:5a7b9ea14056 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
1stefikefi 0:5a7b9ea14056 36
1stefikefi 0:5a7b9ea14056 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
1stefikefi 0:5a7b9ea14056 38
1stefikefi 0:5a7b9ea14056 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:
1stefikefi 0:5a7b9ea14056 40
1stefikefi 0:5a7b9ea14056 41 ```bash
1stefikefi 0:5a7b9ea14056 42 $ mbed compile -S
1stefikefi 0:5a7b9ea14056 43 ```
1stefikefi 0:5a7b9ea14056 44
1stefikefi 0:5a7b9ea14056 45 ## Expected output
1stefikefi 0:5a7b9ea14056 46 The LED on your target turns on and off every 500 milliseconds.
1stefikefi 0:5a7b9ea14056 47
1stefikefi 0:5a7b9ea14056 48
1stefikefi 0:5a7b9ea14056 49 ## Troubleshooting
1stefikefi 0:5a7b9ea14056 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.
