noutram 0:aed251004373 1 # Getting started with Blinky on mbed OS
noutram 0:aed251004373 2
noutram 0:aed251004373 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
noutram 0:aed251004373 4
noutram 0:aed251004373 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
noutram 0:aed251004373 6
noutram 0:aed251004373 7 ## Import the example application
noutram 0:aed251004373 8
noutram 0:aed251004373 9 From the command-line, import the example:
noutram 0:aed251004373 10
noutram 0:aed251004373 11 ```
noutram 0:aed251004373 12 mbed import mbed-os-example-blinky
noutram 0:aed251004373 13 cd mbed-os-example-blinky
noutram 0:aed251004373 14 ```
noutram 0:aed251004373 15
noutram 0:aed251004373 16 ### Now compile
noutram 0:aed251004373 17
noutram 0:aed251004373 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:
noutram 0:aed251004373 19
noutram 0:aed251004373 20 ```
noutram 0:aed251004373 21 mbed compile -m K64F -t ARM
noutram 0:aed251004373 22 ```
noutram 0:aed251004373 23
noutram 0:aed251004373 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
noutram 0:aed251004373 25
noutram 0:aed251004373 26 ```
