Jonathan Austin 0:2757d7abb7d9 2
mbed_official 27:e64a31d541da 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
Jonathan Austin 0:2757d7abb7d9 4
Jonathan Austin 0:2757d7abb7d9 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
Jonathan Austin 0:2757d7abb7d9 6
mbed_official 27:e64a31d541da 7 ## Import the example application
Jonathan Austin 0:2757d7abb7d9 8
mbed_official 27:e64a31d541da 9 From the command-line, import the example:
Jonathan Austin 0:2757d7abb7d9 10
Jonathan Austin 0:2757d7abb7d9 11 ```
Jonathan Austin 0:2757d7abb7d9 12 mbed import mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 13 cd mbed-os-example-blinky
Jonathan Austin 0:2757d7abb7d9 14 ```
Jonathan Austin 0:2757d7abb7d9 15
Jonathan Austin 0:2757d7abb7d9 16 ### Now compile
Jonathan Austin 0:2757d7abb7d9 17
mbed_official 27:e64a31d541da 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:
Jonathan Austin 0:2757d7abb7d9 19
Jonathan Austin 0:2757d7abb7d9 20 ```
Jonathan Austin 0:2757d7abb7d9 21 mbed compile -m K64F -t ARM
Jonathan Austin 0:2757d7abb7d9 22 ```
Jonathan Austin 0:2757d7abb7d9 23
mbed_official 27:e64a31d541da 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
