00003  * @brief   Command Line Interface Module for reading switches
00004  *          Up to 8 switches can be defined on any digital mbed Pin.
00005  *          Provide debounce and edge detection
00006  * @version 1.0
00007  * @date    Feb 2, 2011

00009    Command Line Interface 
00010    Format: command name (arg info)min..max values [optional argument]
00011       swRead (Switch id)0..3  Return Message: GPPS0 id pin debounce state
00012       swInit (Switch id)0..7 (Pin number)0..432 (debounce interval)1..255
00013               Initialize a Limit Switch Process and return Message: GPPS0 id pin debounce state
00014       GPPS0  Return 8 Message: GPPS0 id pin debounce state
00015 
00016    Module Events
00017         On closing of switch, Return Message: GPPS0 id pin debounce state
00018         On Opening of switch, Return Message: GPPS0 id pin debounce state
