| AjK | 1:2f99edb5545c | 39 | * |
| AjK | 1:2f99edb5545c | 40 | * The Mbed library supplies the DigitalIn and DigitalOut objects to allow you |

| AjK | 1:2f99edb5545c | 42 | * |
| AjK | 1:2f99edb5545c | 43 | * Lib17_DIO allows library objects to implement pins without the requirement |
| AjK | 1:2f99edb5545c | 44 | * to link against the Mbed library. This increase portability when using |
| AjK | 1:2f99edb5545c | 45 | * alternate compilers (such as the Code Red GCC C++ compiler for LPCXpresso). |
