AustinKim 0:6d4ac55b6b76 1 # Getting started example for Mbed OS
AustinKim 0:6d4ac55b6b76 2
AustinKim 0:6d4ac55b6b76 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).)
AustinKim 0:6d4ac55b6b76 4
AustinKim 0:6d4ac55b6b76 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
AustinKim 0:6d4ac55b6b76 6
AustinKim 0:6d4ac55b6b76 7 ## Import the example application
AustinKim 0:6d4ac55b6b76 8
AustinKim 0:6d4ac55b6b76 9 From the command-line, import the example:
AustinKim 0:6d4ac55b6b76 10
AustinKim 0:6d4ac55b6b76 11 ```
AustinKim 0:6d4ac55b6b76 12 mbed import mbed-os-example-blinky
AustinKim 0:6d4ac55b6b76 13 cd mbed-os-example-blinky
AustinKim 0:6d4ac55b6b76 14 ```
AustinKim 0:6d4ac55b6b76 15
AustinKim 0:6d4ac55b6b76 16 ### Now compile
AustinKim 0:6d4ac55b6b76 17
AustinKim 0:6d4ac55b6b76 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:
AustinKim 0:6d4ac55b6b76 19
AustinKim 0:6d4ac55b6b76 20 ```
AustinKim 0:6d4ac55b6b76 21 mbed compile -m K64F -t ARM
AustinKim 0:6d4ac55b6b76 22 ```
AustinKim 0:6d4ac55b6b76 23
AustinKim 0:6d4ac55b6b76 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
AustinKim 0:6d4ac55b6b76 25
AustinKim 0:6d4ac55b6b76 26 ```
