stevehousley 4:6bf4cdb7b834 2 - Following program is to emulate Infinity channel switching.
shivikas 0:f4e0c6f139ea 3 - embeds are used to send hotkey combination to switch channel.
shivikas 0:f4e0c6f139ea 4 - CTRL+SHIFT+[1-4] is used to switch among four channels.
shivikas 0:f4e0c6f139ea 5 - LCD screen on mbed application board is used to show switch status and count.
