nprobably 0:8d3802709c6c 1 # Getting started with Blinky on mbed OS
nprobably 0:8d3802709c6c 2
nprobably 0:8d3802709c6c 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
nprobably 0:8d3802709c6c 4
nprobably 0:8d3802709c6c 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
nprobably 0:8d3802709c6c 6
nprobably 0:8d3802709c6c 7 ## Import the example application
nprobably 0:8d3802709c6c 8
nprobably 0:8d3802709c6c 9 From the command-line, import the example:
nprobably 0:8d3802709c6c 10
nprobably 0:8d3802709c6c 11 ```
nprobably 0:8d3802709c6c 12 mbed import mbed-os-example-blinky
nprobably 0:8d3802709c6c 13 cd mbed-os-example-blinky
nprobably 0:8d3802709c6c 14 ```
nprobably 0:8d3802709c6c 15
nprobably 0:8d3802709c6c 16 ### Now compile
nprobably 0:8d3802709c6c 17
nprobably 0:8d3802709c6c 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:
nprobably 0:8d3802709c6c 19
nprobably 0:8d3802709c6c 20 ```
nprobably 0:8d3802709c6c 21 mbed compile -m K64F -t ARM
nprobably 0:8d3802709c6c 22 ```
nprobably 0:8d3802709c6c 23
nprobably 0:8d3802709c6c 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:

nprobably 0:8d3802709c6c 48
nprobably 0:8d3802709c6c 49 1. Connect your mbed device to the computer over USB.
nprobably 0:8d3802709c6c 50 1. Copy the binary file to the mbed device.
nprobably 0:8d3802709c6c 51 1. Press the reset button to start the program.
nprobably 0:8d3802709c6c 52
nprobably 0:8d3802709c6c 53 The LED on your platform turns on and off.
