00002   Hotboards_rtcc Library - setting time and date with compiler macros
00003  Demonstrates the use a MCP7941x clock calendar.  
00004  The Hotboards_rtcc library works with this microchip real time clock
00005  (http://www.hotboards.org).
00006  
00007  This sketch set time and date using compiler macros, and then send through 
00008  serial port every five seconds
00009   The circuit:
00010  *  VDD  -->  3.3v
00011  *  GND  -->  GND
00012  *  SDA  -->  SDA
00013  *  SCL  -->  SCL
