johnAlexander 0:6b7696e7df5e 1 # Getting started example for Mbed OS
johnAlexander 0:6b7696e7df5e 2
johnAlexander 0:6b7696e7df5e 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).)
johnAlexander 0:6b7696e7df5e 4
johnAlexander 0:6b7696e7df5e 5 Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
johnAlexander 0:6b7696e7df5e 6
johnAlexander 0:6b7696e7df5e 7 ## Import the example application
johnAlexander 0:6b7696e7df5e 8
johnAlexander 0:6b7696e7df5e 9 From the command-line, import the example:
johnAlexander 0:6b7696e7df5e 10
johnAlexander 0:6b7696e7df5e 11 ```
johnAlexander 0:6b7696e7df5e 12 mbed import mbed-os-example-blinky
johnAlexander 0:6b7696e7df5e 13 cd mbed-os-example-blinky
johnAlexander 0:6b7696e7df5e 14 ```
johnAlexander 0:6b7696e7df5e 15
johnAlexander 0:6b7696e7df5e 16 ### Now compile
johnAlexander 0:6b7696e7df5e 17
johnAlexander 0:6b7696e7df5e 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:
johnAlexander 0:6b7696e7df5e 19
johnAlexander 0:6b7696e7df5e 20 ```
johnAlexander 0:6b7696e7df5e 21 mbed compile -m K64F -t ARM
johnAlexander 0:6b7696e7df5e 22 ```
johnAlexander 0:6b7696e7df5e 23
johnAlexander 0:6b7696e7df5e 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
johnAlexander 0:6b7696e7df5e 25
johnAlexander 0:6b7696e7df5e 26 ```

johnAlexander 0:6b7696e7df5e 31
johnAlexander 0:6b7696e7df5e 32 ### Program your board
johnAlexander 0:6b7696e7df5e 33
johnAlexander 0:6b7696e7df5e 34 1. Connect your Mbed device to the computer over USB.
johnAlexander 0:6b7696e7df5e 35 1. Copy the binary file to the Mbed device.
johnAlexander 0:6b7696e7df5e 36 1. Press the reset button to start the program.
johnAlexander 0:6b7696e7df5e 37
johnAlexander 0:6b7696e7df5e 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:
