castlefei 0:44701eab0261 1 # Getting started example for Mbed OS
castlefei 0:44701eab0261 2
castlefei 0:44701eab0261 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).)
castlefei 0:44701eab0261 4
castlefei 0:44701eab0261 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
castlefei 0:44701eab0261 6
castlefei 0:44701eab0261 7 ## Import the example application
castlefei 0:44701eab0261 8
castlefei 0:44701eab0261 9 From the command-line, import the example:
castlefei 0:44701eab0261 10
castlefei 0:44701eab0261 11 ```
castlefei 0:44701eab0261 12 mbed import mbed-os-example-blinky
castlefei 0:44701eab0261 13 cd mbed-os-example-blinky
castlefei 0:44701eab0261 14 ```
castlefei 0:44701eab0261 15
castlefei 0:44701eab0261 16 ### Now compile
castlefei 0:44701eab0261 17
castlefei 0:44701eab0261 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:
castlefei 0:44701eab0261 19
castlefei 0:44701eab0261 20 ```
castlefei 0:44701eab0261 21 mbed compile -m K64F -t ARM
castlefei 0:44701eab0261 22 ```
castlefei 0:44701eab0261 23
castlefei 0:44701eab0261 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
castlefei 0:44701eab0261 25
castlefei 0:44701eab0261 26 ```

castlefei 0:44701eab0261 32 ### Program your board
castlefei 0:44701eab0261 33
castlefei 0:44701eab0261 34 1. Connect your Mbed device to the computer over USB.
castlefei 0:44701eab0261 35 1. Copy the binary file to the Mbed device.
castlefei 0:44701eab0261 36 1. Press the reset button to start the program.
castlefei 0:44701eab0261 37
castlefei 0:44701eab0261 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:
