  Hotboards_SpiLcd Library - Hello World
  
  Demonstrates the use a 16x2 LCD display.  The Hotboards_SpiLcd
  library works with all LCD displays that are compatible with the
  SP7032 driver presented on Spi Lcd board (http://www.hotboards.org).
  
  This sketch prints "Hello World!" to the LCD
  and shows the time.
  
  The circuit:
  *  BKL   -->  GND
  *  VDD   -->  3.3v
  *  GND   -->  GND
  *  SCLK  -->  PB_3
  *  SI    -->  PB_5
  *  CS    -->  PC_0
  *  RS    -->  PC_1
  *  RST   -->  PC_2
