/* 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. */ #include "mbed.h" #include "Hotboards_SpiLcd.h" /* initialize an instance of SPI bus,setting the SPI pins*/ SPI device(PA_7,PA_6,PA_5); /* SO, SI, SCK*/ /* initialize the library with the numbers of the interface pins*/ Hotboards_SpiLcd display( device, PB_15, PB_14, PB_13 ); /* SPI, CS, RS, RST */ int main() { /* set the spi frequency to 5MHz*/ device.frequency(5000000); /* initialize internal lcd controller:*/ display.init(); /* Set Cursor on column 2 and Row 0*/ display.setCursor(2,0); /* Print a message */ display.printf( "Row 1" ); /* Set Cursor on column 4 and Row 1*/ display.setCursor(4,1); /* Print another message */ display.printf( "Row 2" ); while(1) { /* infinite loop, doing nothing*/ } }
