diltech 0:9a306207c5b2 2 # Blinky Mbed OS example
diltech 0:9a306207c5b2 3
diltech 0:9a306207c5b2 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/latest/quick-start/index.html). It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/).
diltech 0:9a306207c5b2 5
diltech 0:9a306207c5b2 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).

diltech 0:9a306207c5b2 9 ## Mbed OS build tools
diltech 0:9a306207c5b2 10
diltech 0:9a306207c5b2 11 ### Mbed CLI 2
diltech 0:9a306207c5b2 12 Starting with version 6.5, Mbed OS uses Mbed CLI 2. It uses Ninja as a build system, and CMake to generate the build environment and manage the build process in a compiler-independent manner. If you are working with Mbed OS version prior to 6.5 then check the section [Mbed CLI 1](#mbed-cli-1).
diltech 0:9a306207c5b2 13 1. [Install Mbed CLI 2](https://os.mbed.com/docs/mbed-os/latest/build-tools/install-or-upgrade.html).
diltech 0:9a306207c5b2 14 1. From the command-line, import the example: `mbed-tools import mbed-os-example-blinky`
diltech 0:9a306207c5b2 15 1. Change the current directory to where the project was imported.

diltech 0:9a306207c5b2 17 ### Mbed CLI 1
diltech 0:9a306207c5b2 18 1. [Install Mbed CLI 1](https://os.mbed.com/docs/mbed-os/latest/quick-start/offline-with-mbed-cli.html).
diltech 0:9a306207c5b2 19 1. From the command-line, import the example: `mbed import mbed-os-example-blinky`
diltech 0:9a306207c5b2 20 1. Change the current directory to where the project was imported.

diltech 0:9a306207c5b2 22 ## Application functionality
diltech 0:9a306207c5b2 23
diltech 0:9a306207c5b2 24 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.
diltech 0:9a306207c5b2 25
diltech 0:9a306207c5b2 26 **Note**: This example requires a target with RTOS support, i.e. one with `rtos` declared in `supported_application_profiles` in `targets/targets.json` in [mbed-os](https://github.com/ARMmbed/mbed-os). For non-RTOS targets (usually with small memory sizes), please use [mbed-os-example-blinky-baremetal](https://github.com/ARMmbed/mbed-os-example-blinky-baremetal) instead.

diltech 0:9a306207c5b2 28 ## Building and running
diltech 0:9a306207c5b2 29
diltech 0:9a306207c5b2 30 1. Connect a USB cable between the USB port on the board and the host computer.
diltech 0:9a306207c5b2 31 1. Run the following command to build the example project and program the microcontroller flash memory:
diltech 0:9a306207c5b2 32
diltech 0:9a306207c5b2 33 * Mbed CLI 2
diltech 0:9a306207c5b2 34
diltech 0:9a306207c5b2 35 ```bash
diltech 0:9a306207c5b2 36 $ mbed-tools compile -m <TARGET> -t <TOOLCHAIN> --flash
diltech 0:9a306207c5b2 37 ```
diltech 0:9a306207c5b2 38
diltech 0:9a306207c5b2 39 * Mbed CLI 1
diltech 0:9a306207c5b2 40
diltech 0:9a306207c5b2 41 ```bash
diltech 0:9a306207c5b2 42 $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash
diltech 0:9a306207c5b2 43 ```
diltech 0:9a306207c5b2 44
diltech 0:9a306207c5b2 45 Your PC may take a few minutes to compile your code.
diltech 0:9a306207c5b2 46
diltech 0:9a306207c5b2 47 The binary is located at:
diltech 0:9a306207c5b2 48 * **Mbed CLI 2** - `./cmake_build/mbed-os-example-blinky.bin`</br>
diltech 0:9a306207c5b2 49 * **Mbed CLI 1** - `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`
diltech 0:9a306207c5b2 50
diltech 0:9a306207c5b2 51 Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB.
diltech 0:9a306207c5b2 52
diltech 0:9a306207c5b2 53 ## Expected output
diltech 0:9a306207c5b2 54 The LED on your target turns on and off every 500 milliseconds.
