+  Hotboards_SpiLcd Library - setCursor
+ Demonstrates the use a 16x2 LCD display.  The Hotboards_SpiLcd
+ library works with all LCD displays that are compatible with the
+ ST7032 driver presented on Spi Lcd board (http://www.hotboards.org).
+ This sketch prints to all the positions of the LCD using the
+ setCursor() method:
+  
+  The circuit:
+  *  BKL   -->  GND
+  *  VDD   -->  3.3v
+  *  GND   -->  GND
+  *  SCK   -->  PA_5
+  *  SI    -->  PA_6
+  *  CS    -->  PB_15
+  *  RS    -->  PB_14
+  *  RST   -->  PB_13
+
+ Library and example ported by Diego from Hotboards and originally created 
+ by David A. Mellis
