bpd227 0:903ffe4d4440 1 # Getting started with Blinky on mbed OS
bpd227 0:903ffe4d4440 2
bpd227 0:903ffe4d4440 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
bpd227 0:903ffe4d4440 4
bpd227 0:903ffe4d4440 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
bpd227 0:903ffe4d4440 6
bpd227 0:903ffe4d4440 7 ## Import the example application
bpd227 0:903ffe4d4440 8
bpd227 0:903ffe4d4440 9 From the command-line, import the example:
bpd227 0:903ffe4d4440 10
bpd227 0:903ffe4d4440 11 ```
bpd227 0:903ffe4d4440 12 mbed import mbed-os-example-blinky
bpd227 0:903ffe4d4440 13 cd mbed-os-example-blinky
bpd227 0:903ffe4d4440 14 ```
bpd227 0:903ffe4d4440 15
bpd227 0:903ffe4d4440 16 ### Now compile
bpd227 0:903ffe4d4440 17
bpd227 0:903ffe4d4440 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:
bpd227 0:903ffe4d4440 19
bpd227 0:903ffe4d4440 20 ```
bpd227 0:903ffe4d4440 21 mbed compile -m K64F -t ARM
bpd227 0:903ffe4d4440 22 ```
bpd227 0:903ffe4d4440 23
bpd227 0:903ffe4d4440 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
bpd227 0:903ffe4d4440 25
bpd227 0:903ffe4d4440 26 ```
