+  Hotboards_SpiLcd Library - Writing in diferent rows
+  
+  Demonstrates the use a 16x2 LCD display, specially the functions for scrolling text.
+  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 "[HOLA]" in the upper row of the LCD and then scroll it to the right,
+  then to the left.
+  
+  
+  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 ported by Diego from Hotboards and originally created by
+  David A. Mellis
+  library modified 5 Jul 2009
+  by Limor Fried (http://www.ladyada.net)
+  example added 
+  by Pedro from Hotboards
+  This example code is in the public domain.
