mbed_official 82:abf1b1785bd7 1 # Getting started example for Mbed OS
Jonathan Austin 0:2757d7abb7d9 2
mbed_official 91:3a205782066a 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).)
Jonathan Austin 0:2757d7abb7d9 4
mbed_official 91:3a205782066a 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Jonathan Austin 0:2757d7abb7d9 6
mbed_official 27:e64a31d541da 7 ## Import the example application
Jonathan Austin 0:2757d7abb7d9 8
mbed_official 27:e64a31d541da 9 From the command-line, import the example:
Jonathan Austin 0:2757d7abb7d9 10
Jonathan Austin 0:2757d7abb7d9 11 ```
Jonathan Austin 0:2757d7abb7d9 12 mbed import mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 13 cd mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 14 ```
Jonathan Austin 0:2757d7abb7d9 15
Jonathan Austin 0:2757d7abb7d9 16 ### Now compile
Jonathan Austin 0:2757d7abb7d9 17
mbed_official 93:4b44c2502b00 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:
Jonathan Austin 0:2757d7abb7d9 19
Jonathan Austin 0:2757d7abb7d9 20 ```
Jonathan Austin 0:2757d7abb7d9 21 mbed compile -m K64F -t ARM
Jonathan Austin 0:2757d7abb7d9 22 ```
Jonathan Austin 0:2757d7abb7d9 23
mbed_official 27:e64a31d541da 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
