cornetlin 0:1f63a5db1425 1 # Getting started with Blinky on mbed OS
cornetlin 0:1f63a5db1425 2
cornetlin 0:1f63a5db1425 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
cornetlin 0:1f63a5db1425 4
cornetlin 0:1f63a5db1425 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
cornetlin 0:1f63a5db1425 6
cornetlin 0:1f63a5db1425 7 ## Import the example application
cornetlin 0:1f63a5db1425 8
cornetlin 0:1f63a5db1425 9 From the command-line, import the example:
cornetlin 0:1f63a5db1425 10
cornetlin 0:1f63a5db1425 11 ```
cornetlin 0:1f63a5db1425 12 mbed import mbed-os-example-blinky
cornetlin 0:1f63a5db1425 13 cd mbed-os-example-blinky
cornetlin 0:1f63a5db1425 14 ```
cornetlin 0:1f63a5db1425 15
cornetlin 0:1f63a5db1425 16 ### Now compile
cornetlin 0:1f63a5db1425 17
cornetlin 0:1f63a5db1425 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:
cornetlin 0:1f63a5db1425 19
cornetlin 0:1f63a5db1425 20 ```
cornetlin 0:1f63a5db1425 21 mbed compile -m K64F -t ARM
cornetlin 0:1f63a5db1425 22 ```
cornetlin 0:1f63a5db1425 23
cornetlin 0:1f63a5db1425 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
cornetlin 0:1f63a5db1425 25
cornetlin 0:1f63a5db1425 26 ```
