pavle1 0:3d05e6818035 2 # Blinky Mbed OS example
pavle1 0:3d05e6818035 3
pavle1 0:3d05e6818035 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/).
pavle1 0:3d05e6818035 5
pavle1 0:3d05e6818035 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).
pavle1 0:3d05e6818035 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).)
pavle1 0:3d05e6818035 8
pavle1 0:3d05e6818035 9 1. [Install Mbed CLI](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
pavle1 0:3d05e6818035 10
pavle1 0:3d05e6818035 11 1. Clone this repository on your system, and change the current directory to where the project was cloned:
pavle1 0:3d05e6818035 12
pavle1 0:3d05e6818035 13 ```bash
pavle1 0:3d05e6818035 14 $ git clone git@github.com:armmbed/mbed-os-example-blinky && cd mbed-os-example-blinky
pavle1 0:3d05e6818035 15 ```
pavle1 0:3d05e6818035 16
pavle1 0:3d05e6818035 17 Alternatively, you can download the example project with Arm Mbed CLI using the `import` subcommand:
pavle1 0:3d05e6818035 18
pavle1 0:3d05e6818035 19 ```bash
pavle1 0:3d05e6818035 20 $ mbed import mbed-os-example-blinky && cd mbed-os-example-blinky
pavle1 0:3d05e6818035 21 ```
pavle1 0:3d05e6818035 22
pavle1 0:3d05e6818035 23
pavle1 0:3d05e6818035 24 ## Application functionality
pavle1 0:3d05e6818035 25
pavle1 0:3d05e6818035 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.
pavle1 0:3d05e6818035 27
pavle1 0:3d05e6818035 28 ## Building and running
pavle1 0:3d05e6818035 29
pavle1 0:3d05e6818035 30 1. Connect a USB cable between the USB port on the board and the host computer.
pavle1 0:3d05e6818035 31 2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory:
pavle1 0:3d05e6818035 32 ```bash
pavle1 0:3d05e6818035 33 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
pavle1 0:3d05e6818035 34 ```
pavle1 0:3d05e6818035 35 The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`.
pavle1 0:3d05e6818035 36
pavle1 0:3d05e6818035 37 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
pavle1 0:3d05e6818035 38
pavle1 0:3d05e6818035 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:
pavle1 0:3d05e6818035 40
pavle1 0:3d05e6818035 41 ```bash
pavle1 0:3d05e6818035 42 $ mbed compile -S
pavle1 0:3d05e6818035 43 ```
pavle1 0:3d05e6818035 44
pavle1 0:3d05e6818035 45 ## Expected output
pavle1 0:3d05e6818035 46 The LED on your target turns on and off every 500 milliseconds.

pavle1 0:3d05e6818035 49 ## Troubleshooting
pavle1 0:3d05e6818035 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.
