jhanson2 0:0b59e37a2f9b 1 # Getting started with Blinky on mbed OS
jhanson2 0:0b59e37a2f9b 2
jhanson2 0:0b59e37a2f9b 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
jhanson2 0:0b59e37a2f9b 4
jhanson2 0:0b59e37a2f9b 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
jhanson2 0:0b59e37a2f9b 6
jhanson2 0:0b59e37a2f9b 7 ## Import the example application
jhanson2 0:0b59e37a2f9b 8
jhanson2 0:0b59e37a2f9b 9 From the command-line, import the example:
jhanson2 0:0b59e37a2f9b 10
jhanson2 0:0b59e37a2f9b 11 ```
jhanson2 0:0b59e37a2f9b 12 mbed import mbed-os-example-blinky
jhanson2 0:0b59e37a2f9b 13 cd mbed-os-example-blinky
jhanson2 0:0b59e37a2f9b 14 ```
jhanson2 0:0b59e37a2f9b 15
jhanson2 0:0b59e37a2f9b 16 ### Now compile
jhanson2 0:0b59e37a2f9b 17
jhanson2 0:0b59e37a2f9b 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:
jhanson2 0:0b59e37a2f9b 19
jhanson2 0:0b59e37a2f9b 20 ```
jhanson2 0:0b59e37a2f9b 21 mbed compile -m K64F -t ARM
jhanson2 0:0b59e37a2f9b 22 ```
jhanson2 0:0b59e37a2f9b 23
jhanson2 0:0b59e37a2f9b 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
jhanson2 0:0b59e37a2f9b 25
