martwerl 0:f5de9cd30ded 1 # Getting started example for Mbed OS
martwerl 0:f5de9cd30ded 2
martwerl 0:f5de9cd30ded 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).)
martwerl 0:f5de9cd30ded 4
martwerl 0:f5de9cd30ded 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
martwerl 0:f5de9cd30ded 6
martwerl 0:f5de9cd30ded 7 ## Import the example application
martwerl 0:f5de9cd30ded 8
martwerl 0:f5de9cd30ded 9 From the command-line, import the example:
martwerl 0:f5de9cd30ded 10
martwerl 0:f5de9cd30ded 11 ```
martwerl 0:f5de9cd30ded 12 mbed import mbed-os-example-blinky
martwerl 0:f5de9cd30ded 13 cd mbed-os-example-blinky
martwerl 0:f5de9cd30ded 14 ```
martwerl 0:f5de9cd30ded 15
martwerl 0:f5de9cd30ded 16 ### Now compile
martwerl 0:f5de9cd30ded 17
martwerl 0:f5de9cd30ded 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:
martwerl 0:f5de9cd30ded 19
martwerl 0:f5de9cd30ded 20 ```
martwerl 0:f5de9cd30ded 21 mbed compile -m K64F -t ARM
martwerl 0:f5de9cd30ded 22 ```
martwerl 0:f5de9cd30ded 23
martwerl 0:f5de9cd30ded 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
martwerl 0:f5de9cd30ded 25
martwerl 0:f5de9cd30ded 26 ```

martwerl 0:f5de9cd30ded 30 ```
martwerl 0:f5de9cd30ded 31
martwerl 0:f5de9cd30ded 32 ### Program your board
martwerl 0:f5de9cd30ded 33
martwerl 0:f5de9cd30ded 34 1. Connect your Mbed device to the computer over USB.
martwerl 0:f5de9cd30ded 35 1. Copy the binary file to the Mbed device.
martwerl 0:f5de9cd30ded 36 1. Press the reset button to start the program.
martwerl 0:f5de9cd30ded 37
martwerl 0:f5de9cd30ded 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:
