+  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
+
