00002   Hotboards_Spilcd Library - Cursor
00003 
00004  Demonstrates the use a 16x2 LCD display.  The Hotboards_SpiLcd
00005  library works with all LCD displays that are compatible with the
00006  ST7032 driver presented on Spi Lcd board (http://www.hotboards.org).
00007  This sketch prints "Hello World!" to the LCD and
00008  uses the cursor()  and noCursor() methods to turn
00009  on and off the cursor.
00010  The circuit:
00011   *  BKL   -->  GND
00012   *  VDD   -->  3.3v
00013   *  GND   -->  GND
00014   *  SCK   -->  PA_5
00015   *  SI    -->  PA_6
00016   *  CS    -->  PB_15
00017   *  RS    -->  PB_14
00018   *  RST   -->  PB_13
