AlejandroZamudio 0:145a79fbba51 2 Hotboards_SpiLcd Library - Hello World
AlejandroZamudio 0:145a79fbba51 3
AlejandroZamudio 0:145a79fbba51 4 Demonstrates the use a 16x2 LCD display. The Hotboards_SpiLcd
AlejandroZamudio 0:145a79fbba51 5 library works with all LCD displays that are compatible with the
AlejandroZamudio 0:145a79fbba51 6 SP7032 driver presented on Spi Lcd board (http://www.hotboards.org).

AlejandroZamudio 0:145a79fbba51 8 This sketch prints "Hello World!" to the LCD
AlejandroZamudio 0:145a79fbba51 9 and shows the time.
AlejandroZamudio 0:145a79fbba51 10
AlejandroZamudio 0:145a79fbba51 11 The circuit:
AlejandroZamudio 0:145a79fbba51 12 * BKL --> GND
AlejandroZamudio 0:145a79fbba51 13 * VDD --> 3.3v
AlejandroZamudio 0:145a79fbba51 14 * GND --> GND
AlejandroZamudio 0:145a79fbba51 15 * SCLK --> PB_3
AlejandroZamudio 0:145a79fbba51 16 * SI --> PB_5
AlejandroZamudio 0:145a79fbba51 17 * CS --> PC_0
AlejandroZamudio 0:145a79fbba51 18 * RS --> PC_1
AlejandroZamudio 0:145a79fbba51 19 * RST --> PC_2
