jauming 1:9b126a535f52 1 # Getting started with EinkShield_HelloWorld on mbed OS
jauming 0:6f162728dcca 2
jauming 1:9b126a535f52 3 This guide reviews the steps required to get EinkShield_HelloWorld working on an mbed OS platform.
jauming 0:6f162728dcca 4
jauming 0:6f162728dcca 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
jauming 0:6f162728dcca 6
jauming 0:6f162728dcca 7 ## Import the example application
jauming 0:6f162728dcca 8
jauming 0:6f162728dcca 9 From the command-line, import the example:
jauming 0:6f162728dcca 10
jauming 0:6f162728dcca 11 ```
jauming 1:9b126a535f52 12 mbed import EinkShield_HelloWorld
jauming 1:9b126a535f52 13 cd EinkShield_HelloWorld
jauming 0:6f162728dcca 14 ```
jauming 0:6f162728dcca 15
jauming 0:6f162728dcca 16 ### Now compile
jauming 0:6f162728dcca 17
jauming 0:6f162728dcca 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:
jauming 0:6f162728dcca 19
jauming 0:6f162728dcca 20 ```
jauming 0:6f162728dcca 21 mbed compile -m KL25Z -t ARM
jauming 0:6f162728dcca 22 ```
jauming 0:6f162728dcca 23
jauming 0:6f162728dcca 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
jauming 0:6f162728dcca 25
jauming 0:6f162728dcca 26 ```
