shivanandgowdakr 0:7c7d15e2f39e 1 # Getting started example for Mbed OS
shivanandgowdakr 0:7c7d15e2f39e 2
shivanandgowdakr 0:7c7d15e2f39e 3 This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform. (Note: To see a rendered example you can import into the Arm Online Compiler, please see our [quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).)
shivanandgowdakr 0:7c7d15e2f39e 4
shivanandgowdakr 0:7c7d15e2f39e 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
shivanandgowdakr 0:7c7d15e2f39e 6
shivanandgowdakr 0:7c7d15e2f39e 7 ## Import the example application
shivanandgowdakr 0:7c7d15e2f39e 8
shivanandgowdakr 0:7c7d15e2f39e 9 From the command-line, import the example:
shivanandgowdakr 0:7c7d15e2f39e 10
shivanandgowdakr 0:7c7d15e2f39e 11 ```
shivanandgowdakr 0:7c7d15e2f39e 12 mbed import mbed-os-example-blinky
shivanandgowdakr 0:7c7d15e2f39e 13 cd mbed-os-example-blinky
shivanandgowdakr 0:7c7d15e2f39e 14 ```
shivanandgowdakr 0:7c7d15e2f39e 15
shivanandgowdakr 0:7c7d15e2f39e 16 ### Now compile
shivanandgowdakr 0:7c7d15e2f39e 17
shivanandgowdakr 0:7c7d15e2f39e 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:
shivanandgowdakr 0:7c7d15e2f39e 19
shivanandgowdakr 0:7c7d15e2f39e 20 ```
shivanandgowdakr 0:7c7d15e2f39e 21 mbed compile -m K64F -t ARM
shivanandgowdakr 0:7c7d15e2f39e 22 ```
shivanandgowdakr 0:7c7d15e2f39e 23
shivanandgowdakr 0:7c7d15e2f39e 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
shivanandgowdakr 0:7c7d15e2f39e 25
shivanandgowdakr 0:7c7d15e2f39e 26 ```
