Pitiwut 0:71e6966178f5 1 # Getting started with Blinky on mbed OS
Pitiwut 0:71e6966178f5 2
Pitiwut 0:71e6966178f5 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
Pitiwut 0:71e6966178f5 4
Pitiwut 0:71e6966178f5 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Pitiwut 0:71e6966178f5 6
Pitiwut 0:71e6966178f5 7 ## Import the example application
Pitiwut 0:71e6966178f5 8
Pitiwut 0:71e6966178f5 9 From the command-line, import the example:
Pitiwut 0:71e6966178f5 10
Pitiwut 0:71e6966178f5 11 ```
Pitiwut 0:71e6966178f5 12 mbed import mbed-os-example-blinky
Pitiwut 0:71e6966178f5 13 cd mbed-os-example-blinky
Pitiwut 0:71e6966178f5 14 ```
Pitiwut 0:71e6966178f5 15
Pitiwut 0:71e6966178f5 16 ### Now compile
Pitiwut 0:71e6966178f5 17
Pitiwut 0:71e6966178f5 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:
Pitiwut 0:71e6966178f5 19
Pitiwut 0:71e6966178f5 20 ```
Pitiwut 0:71e6966178f5 21 mbed compile -m K64F -t ARM
Pitiwut 0:71e6966178f5 22 ```
Pitiwut 0:71e6966178f5 23
Pitiwut 0:71e6966178f5 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Pitiwut 0:71e6966178f5 25
Pitiwut 0:71e6966178f5 26 ```
