Contributions are an important part of the platform, and our goal is to make it as simple as possible to become a contributor. + +To encourage productive collaboration, as well as robust, consistent and maintainable code, we have a set of guidelines for [contributing to Mbed OS](https://os.mbed.com/docs/mbed-os/latest/contributing/index.html).

It contains an application that repeatedly blinks an LED on supported [Mbed boards](https://os.mbed.com/platforms/). + +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). +(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).) + +1.

Connect a USB cable between the USB port on the board and the host computer. +2. <a name="build_cmd"></a> Run the following command to build the example project and program the microcontroller flash memory: + ```bash + $ mbed compile -m <TARGET> -t <TOOLCHAIN> --flash + ``` +The binary is located at `./BUILD/<TARGET>/<TOOLCHAIN>/mbed-os-example-blinky.bin`. + +Alternatively, you can manually copy the binary to the board, which you mount on the host computer over USB. + +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: + +```bash +$ mbed compile -S +``` + +## Expected output +The LED on your target turns on and off every 500 milliseconds. + + +## Troubleshooting +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. + +## Related Links + +* [Mbed OS Stats API](https://os.mbed.com/docs/latest/apis/mbed-statistics.html). +* [Mbed OS Configuration](https://os.mbed.com/docs/latest/reference/configuration.html). +* [Mbed OS Serial Communication](https://os.mbed.com/docs/latest/tutorials/serial-communication.html). +* [Mbed OS bare metal](https://os.mbed.com/docs/mbed-os/latest/reference/mbed-os-bare-metal.html). +* [Mbed boards](https://os.mbed.com/platforms/). + +### License and contributions + +The software is provided under Apache-2.0 license.
