+ Hotboards_SpiLcd Library - Writing in diferent rows
+
+ Demonstrates the use a 16x2 LCD display, specially the function setCursor.
+ 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 "Row 1" in the upper row of the LCD
+ & prints "Row 2" in the lower row of the LCD
+
+ 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.
