This is a very simple guide, reviewing the steps required to get Blinky working on an Mbed OS platform.
Mbed OS Blinky
This example shows the use of a DigitalOut object to represent an LED and use of the nonblocking Thread::wait()
call. Using nonblocking calls is good practice because Mbed OS can schedule and run other threads while the first thread is waiting.
Building this example
Building with Arm Mbed CLI
To use Mbed CLI to build this example, follow the instructions in the documentation. The instructions here relate to using the Arm Online Compiler.
To use the Online Compiler, import this code into the Online Compiler, and select your platform from the top right. Compile the code using the compile button, load it onto your board and press the reset button on the board. The code will run on the board, and you will see the LED blink.
You can find more instructions for using the Mbed Online Compiler in the documentation.

# Getting started with Blinky on mbed OS This guide reviews the steps required to get Blinky working on an mbed OS platform. Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). ## Import the example application From the command-line, import the example: ``` mbed import mbed-os-example-blinky cd mbed-os-example-blinky ``` ### Now compile Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5: ``` mbed compile -m K64F -t ARM ``` Your PC may take a few minutes to compile your code. At the end, you see the following result: ``` [snip] +----------------------------+-------+-------+------+ | Module | .text | .data | .bss | +----------------------------+-------+-------+------+ | Misc | 13939 | 24 | 1372 | | core/hal | 16993 | 96 | 296 | | core/rtos | 7384 | 92 | 4204 | | features/FEATURE_IPV4 | 80 | 0 | 176 | | frameworks/greentea-client | 1830 | 60 | 44 | | frameworks/utest | 2392 | 512 | 292 | | Subtotals | 42618 | 784 | 6384 | +----------------------------+-------+-------+------+ Allocated Heap: unknown Allocated Stack: unknown Total Static RAM memory (data + bss): 7168 bytes Total RAM memory (data + bss + heap + stack): 7168 bytes Total Flash memory (text + data + misc): 43402 bytes Image: .\.build\K64F\ARM\mbed-os-example-blinky.bin ``` ### Program your board 1. Connect your mbed device to the computer over USB. 1. Copy the binary file to the mbed device. 1. Press the reset button to start the program. The LED on your platform turns on and off. ## 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.
