+ Hotboards_SpiLcd Library - Hello World
+
+ Demonstrates the use a 16x2 LCD display. The Hotboards_SpiLcd
+ library works with all LCD displays that are compatible with the
+ SP7032 driver presented on Spi Lcd board (http://www.hotboards.org).
+
+ This sketch prints "Hello World!" to the LCD
+ and shows the time.
+
+ The circuit:
+ * BKL --> GND
+ * VDD --> 3.3v
+ * GND --> GND
+ * SCLK --> PB_3
+ * SI --> PB_5
+ * CS --> PC_0
+ * RS --> PC_1
+ * RST --> PC_2
+
+ Library and example ported by Diego from Hotboards and originally cretaed by
+ by David A. Mellis
+ library modified 5 Jul 2009
+ by Limor Fried (http://www.ladyada.net)
+ example added 9 Jul 2009
+ by Tom Igoe
+ modified 22 Nov 2010
+ by Tom Igoe
+ This example code is in the public domain.
