+ 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
+ library modified 5 Jul 2009
+ by Limor Fried (http://www.ladyada.net)
+ example added 9 Jul 2009
