anfontanelli 0:82a5f03b7eb4 1 # Getting started example for Mbed OS
anfontanelli 0:82a5f03b7eb4 2
anfontanelli 0:82a5f03b7eb4 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).)
anfontanelli 0:82a5f03b7eb4 4
anfontanelli 0:82a5f03b7eb4 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
anfontanelli 0:82a5f03b7eb4 6
anfontanelli 0:82a5f03b7eb4 7 ## Import the example application
anfontanelli 0:82a5f03b7eb4 8
anfontanelli 0:82a5f03b7eb4 9 From the command-line, import the example:
anfontanelli 0:82a5f03b7eb4 10
anfontanelli 0:82a5f03b7eb4 11 ```
anfontanelli 0:82a5f03b7eb4 12 mbed import mbed-os-example-blinky
anfontanelli 0:82a5f03b7eb4 13 cd mbed-os-example-blinky
anfontanelli 0:82a5f03b7eb4 14 ```
anfontanelli 0:82a5f03b7eb4 15
anfontanelli 0:82a5f03b7eb4 16 ### Now compile
anfontanelli 0:82a5f03b7eb4 17
anfontanelli 0:82a5f03b7eb4 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:
anfontanelli 0:82a5f03b7eb4 19
anfontanelli 0:82a5f03b7eb4 20 ```
anfontanelli 0:82a5f03b7eb4 21 mbed compile -m K64F -t ARM
anfontanelli 0:82a5f03b7eb4 22 ```
anfontanelli 0:82a5f03b7eb4 23
anfontanelli 0:82a5f03b7eb4 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
anfontanelli 0:82a5f03b7eb4 25
anfontanelli 0:82a5f03b7eb4 26 ```

anfontanelli 0:82a5f03b7eb4 31
anfontanelli 0:82a5f03b7eb4 32 ### Program your board
anfontanelli 0:82a5f03b7eb4 33
anfontanelli 0:82a5f03b7eb4 34 1. Connect your Mbed device to the computer over USB.
anfontanelli 0:82a5f03b7eb4 35 1. Copy the binary file to the Mbed device.
anfontanelli 0:82a5f03b7eb4 36 1. Press the reset button to start the program.
anfontanelli 0:82a5f03b7eb4 37
anfontanelli 0:82a5f03b7eb4 38 The LED on your platform turns on and off. The main thread will additionally take a snapshot of the device's runtime statistics and display it over serial to your PC. The snapshot includes:
