gidiana 12:a34ecb37c03f 1 # Getting started example for Mbed OS
gidiana 12:a34ecb37c03f 2
gidiana 12:a34ecb37c03f 3 This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform.
gidiana 12:a34ecb37c03f 4
gidiana 12:a34ecb37c03f 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
gidiana 12:a34ecb37c03f 6
gidiana 12:a34ecb37c03f 7 ## Import the example application
gidiana 12:a34ecb37c03f 8
gidiana 12:a34ecb37c03f 9 From the command-line, import the example:
gidiana 12:a34ecb37c03f 10
gidiana 12:a34ecb37c03f 11 ```
gidiana 12:a34ecb37c03f 12 mbed import mbed-os-example-blinky
gidiana 12:a34ecb37c03f 13 cd mbed-os-example-blinky
gidiana 12:a34ecb37c03f 14 ```
gidiana 12:a34ecb37c03f 15
gidiana 12:a34ecb37c03f 16 ### Now compile
gidiana 12:a34ecb37c03f 17
gidiana 12:a34ecb37c03f 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:
gidiana 12:a34ecb37c03f 19
gidiana 12:a34ecb37c03f 20 ```
gidiana 12:a34ecb37c03f 21 mbed compile -m K64F -t ARM
gidiana 12:a34ecb37c03f 22 ```
gidiana 12:a34ecb37c03f 23
gidiana 12:a34ecb37c03f 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
gidiana 12:a34ecb37c03f 25
gidiana 12:a34ecb37c03f 26 ```
