whz861025 0:088a3171bdab 1 # Getting started example for Mbed OS
whz861025 0:088a3171bdab 2
whz861025 0:088a3171bdab 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).)
whz861025 0:088a3171bdab 4
whz861025 0:088a3171bdab 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
whz861025 0:088a3171bdab 6
whz861025 0:088a3171bdab 7 ## Import the example application
whz861025 0:088a3171bdab 8
whz861025 0:088a3171bdab 9 From the command-line, import the example:
whz861025 0:088a3171bdab 10
whz861025 0:088a3171bdab 11 ```
whz861025 0:088a3171bdab 12 mbed import mbed-os-example-blinky
whz861025 0:088a3171bdab 13 cd mbed-os-example-blinky
whz861025 0:088a3171bdab 14 ```
whz861025 0:088a3171bdab 15
whz861025 0:088a3171bdab 16 ### Now compile
whz861025 0:088a3171bdab 17
whz861025 0:088a3171bdab 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:
whz861025 0:088a3171bdab 19
whz861025 0:088a3171bdab 20 ```
whz861025 0:088a3171bdab 21 mbed compile -m K64F -t ARM
whz861025 0:088a3171bdab 22 ```
whz861025 0:088a3171bdab 23
whz861025 0:088a3171bdab 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
whz861025 0:088a3171bdab 25
whz861025 0:088a3171bdab 26 ```
