Galib_Rahman 0:7e748374bdff 1 # Getting started example for Mbed OS
Galib_Rahman 0:7e748374bdff 2
Galib_Rahman 0:7e748374bdff 3 This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform.
Galib_Rahman 0:7e748374bdff 4
Galib_Rahman 0:7e748374bdff 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Galib_Rahman 0:7e748374bdff 6
Galib_Rahman 0:7e748374bdff 7 ## Import the example application
Galib_Rahman 0:7e748374bdff 8
Galib_Rahman 0:7e748374bdff 9 From the command-line, import the example:
Galib_Rahman 0:7e748374bdff 10
Galib_Rahman 0:7e748374bdff 11 ```
Galib_Rahman 0:7e748374bdff 12 mbed import mbed-os-example-blinky
Galib_Rahman 0:7e748374bdff 13 cd mbed-os-example-blinky
Galib_Rahman 0:7e748374bdff 14 ```
Galib_Rahman 0:7e748374bdff 15
Galib_Rahman 0:7e748374bdff 16 ### Now compile
Galib_Rahman 0:7e748374bdff 17
Galib_Rahman 0:7e748374bdff 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 5:
Galib_Rahman 0:7e748374bdff 19
Galib_Rahman 0:7e748374bdff 20 ```
Galib_Rahman 0:7e748374bdff 21 mbed compile -m K64F -t ARM
Galib_Rahman 0:7e748374bdff 22 ```
Galib_Rahman 0:7e748374bdff 23
Galib_Rahman 0:7e748374bdff 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
Galib_Rahman 0:7e748374bdff 25
Galib_Rahman 0:7e748374bdff 26 ```
