hkjung | 0:98226e0983af | 2 | |
hkjung | 0:98226e0983af | 3 | This guide reviews the steps required to get Blinky with the addition of dynamic OS statistics working on an Mbed OS platform. (Note: To see a rendered example you can import into the Arm Online Compiler, please see our [quick start](https://os.mbed.com/docs/mbed-os/latest/quick-start/online-with-the-online-compiler.html#importing-the-code).) |
hkjung | 0:98226e0983af | 4 | |
hkjung | 0:98226e0983af | 5 | Please install [Mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli). |
hkjung | 0:98226e0983af | 6 | |
hkjung | 0:98226e0983af | 7 | ## Import the example application |
hkjung | 0:98226e0983af | 8 | |
hkjung | 0:98226e0983af | 9 | From the command-line, import the example: |
hkjung | 0:98226e0983af | 10 | |
hkjung | 0:98226e0983af | 11 | ``` |
hkjung | 0:98226e0983af | 12 | mbed import mbed-os-example-blinky |
hkjung | 0:98226e0983af | 13 | cd mbed-os-example-blinky |
hkjung | 0:98226e0983af | 14 | ``` |
hkjung | 0:98226e0983af | 15 | |
hkjung | 0:98226e0983af | 16 | ### Now compile |
hkjung | 0:98226e0983af | 17 | |
hkjung | 0:98226e0983af | 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: |
hkjung | 0:98226e0983af | 19 | |
hkjung | 0:98226e0983af | 20 | ``` |
hkjung | 0:98226e0983af | 21 | mbed compile -m K64F -t ARM |
hkjung | 0:98226e0983af | 22 | ``` |
hkjung | 0:98226e0983af | 23 | |
hkjung | 0:98226e0983af | 24 | Your PC may take a few minutes to compile your code. At the end, you see the following result: |
hkjung | 0:98226e0983af | 25 | |
