Hotboards 0:9e8b1e9bc6ca 3
Hotboards 0:9e8b1e9bc6ca 4 Demonstrates the use a 16x2 LCD display. The Hotboards_SpiLcd
Hotboards 0:9e8b1e9bc6ca 5 library works with all LCD displays that are compatible with the
Hotboards 0:9e8b1e9bc6ca 6 ST7032 driver presented on Spi Lcd board (http://www.hotboards.org).
Hotboards 0:9e8b1e9bc6ca 7 This sketch prints "Hello World!" to the LCD and
Hotboards 0:9e8b1e9bc6ca 8 uses the cursor() and noCursor() methods to turn
Hotboards 0:9e8b1e9bc6ca 9 on and off the cursor.

Hotboards 0:9e8b1e9bc6ca 11 * BKL --> GND
Hotboards 0:9e8b1e9bc6ca 12 * VDD --> 3.3v
Hotboards 0:9e8b1e9bc6ca 13 * GND --> GND
Hotboards 0:9e8b1e9bc6ca 14 * SCK --> PA_5
Hotboards 0:9e8b1e9bc6ca 15 * SI --> PA_6
Hotboards 0:9e8b1e9bc6ca 16 * CS --> PB_15
Hotboards 0:9e8b1e9bc6ca 17 * RS --> PB_14
Hotboards 0:9e8b1e9bc6ca 18 * RST --> PB_13
