Noriaki Mitsunaga / Mbed 2 deprecated IS_Rocker

This is a sample program to use a rocker IS switch from NKK. It reads a file from SD card and send to the switch. Supported file format is the one that is used by a NKK\'s editor for IS series switches. Part of this program is derived from a sample program for PIC micro cotnroller written by NKK.

Dependencies: mbed SDFileSystem
