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.

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:
