Glaxys_finest1 0:66a265dc3146 1 # Getting started example for Mbed OS
Glaxys_finest1 0:66a265dc3146 2
Glaxys_finest1 0:66a265dc3146 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).)
Glaxys_finest1 0:66a265dc3146 4
Glaxys_finest1 0:66a265dc3146 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Glaxys_finest1 0:66a265dc3146 6
Glaxys_finest1 0:66a265dc3146 7 ## Import the example application
Glaxys_finest1 0:66a265dc3146 8
Glaxys_finest1 0:66a265dc3146 9 From the command-line, import the example:
Glaxys_finest1 0:66a265dc3146 10
Glaxys_finest1 0:66a265dc3146 11 ```
Glaxys_finest1 0:66a265dc3146 12 mbed import mbed-os-example-blinky
Glaxys_finest1 0:66a265dc3146 13 cd mbed-os-example-blinky
Glaxys_finest1 0:66a265dc3146 14 ```
Glaxys_finest1 0:66a265dc3146 15
Glaxys_finest1 0:66a265dc3146 16 ### Now compile
Glaxys_finest1 0:66a265dc3146 17
Glaxys_finest1 0:66a265dc3146 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:
Glaxys_finest1 0:66a265dc3146 19
Glaxys_finest1 0:66a265dc3146 20 ```
Glaxys_finest1 0:66a265dc3146 21 mbed compile -m K64F -t ARM
Glaxys_finest1 0:66a265dc3146 22 ```
Glaxys_finest1 0:66a265dc3146 23
Glaxys_finest1 0:66a265dc3146 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Glaxys_finest1 0:66a265dc3146 25
Glaxys_finest1 0:66a265dc3146 26 ```
