+ LiquidCrystal Library - Blink
+ 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 "Hello World!" to the LCD and makes the
+ cursor block blink.
+ 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 cretaed by
+ by David A. Mellis
