+ 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
