bleis 0:8bd49b071be9 2
bleis 0:8bd49b071be9 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
bleis 0:8bd49b071be9 4
bleis 0:8bd49b071be9 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
bleis 0:8bd49b071be9 6
bleis 0:8bd49b071be9 7 ## Import the example application
bleis 0:8bd49b071be9 8
bleis 0:8bd49b071be9 9 From the command-line, import the example:
bleis 0:8bd49b071be9 10
bleis 0:8bd49b071be9 11 ```
bleis 0:8bd49b071be9 12 mbed import mbed-os-example-blinky
bleis 0:8bd49b071be9 13 cd mbed-os-example-blinky
bleis 0:8bd49b071be9 14 ```
bleis 0:8bd49b071be9 15
bleis 0:8bd49b071be9 16 ### Now compile
bleis 0:8bd49b071be9 17
bleis 0:8bd49b071be9 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:
bleis 0:8bd49b071be9 19
bleis 0:8bd49b071be9 20 ```
bleis 0:8bd49b071be9 21 mbed compile -m K64F -t ARM
bleis 0:8bd49b071be9 22 ```
bleis 0:8bd49b071be9 23
bleis 0:8bd49b071be9 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
bleis 0:8bd49b071be9 25
