maclobdell 0:181267edd351 1 # Getting started with Blinky on mbed OS
maclobdell 0:181267edd351 2
maclobdell 0:181267edd351 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
maclobdell 0:181267edd351 4
maclobdell 0:181267edd351 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
maclobdell 0:181267edd351 6
maclobdell 0:181267edd351 7 ## Import the example application
maclobdell 0:181267edd351 8
maclobdell 0:181267edd351 9 From the command-line, import the example:
maclobdell 0:181267edd351 10
maclobdell 0:181267edd351 11 ```
maclobdell 0:181267edd351 12 mbed import mbed-os-example-blinky
maclobdell 0:181267edd351 13 cd mbed-os-example-blinky
maclobdell 0:181267edd351 14 ```
maclobdell 0:181267edd351 15
maclobdell 0:181267edd351 16 ### Now compile
maclobdell 0:181267edd351 17
maclobdell 0:181267edd351 18 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:
maclobdell 0:181267edd351 19
maclobdell 0:181267edd351 20 ```
maclobdell 0:181267edd351 21 mbed compile -m K64F -t ARM
maclobdell 0:181267edd351 22 ```
maclobdell 0:181267edd351 23
maclobdell 0:181267edd351 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
maclobdell 0:181267edd351 25
