Ciao a tutti,
vi espongo il mio problema: ho collegato ad arduino uno lo shield come da oggetto del topic (allego foto); cercando in rete ho trovato la libreria con i relativi esempi (allego zip).
Volevo provare ad eseguire una demo e ho caricato il seguente sketch:
// UTFT_Demo_320x240 (C)2012 uCtronics
// web: http://www.uctronics.com
// UTFT_Demo_320x240 is derived from
// UTFT_Demo_320x240 (C)2010 Henning Karlsen
// web: http://www.henningkarlsen.com/electronics
// to fit for our 3.2 inch TFT LCD shield for Arduino/Maple/Chipkit
//
// This program is a demo of how to use most of the functions
// of the library with a supported display modules.
//
// This demo was made for modules with a screen resolution
// of 320x240 pixels.
//
// This program requires the UTFT library (8bit mode)
// and the code is compatible with both UNO and Mega board.
// No code modification required.
//
#include <UTFT.h>
#include <SD.h>
#include <Wire.h>
// Declare which fonts we will be using
extern uint8_t SmallFont[];
// Uncomment the next line for Arduino 2009/Uno
//UTFT(byte model, int RS, int WR,int CS,int RD)
//UTFT myGLCD(ITDB32S,A1,A2,A0,A3); // Remember to change the model parameter to suit your display module!
UTFT myGLCD(SSD1289 8,A1,A2,A0,A3);

myGLCD.InitLCD();

ho commentato la riga "//UTFT myGLCD(ITDB32S,A1,A2,A0,A3); // Remember to change the model parameter to suit your display module!" in quanto leggendo una pagina su internet, dicevamo che per questo display bisognava inserire la riga "UTFT myGLCD(SSD1289 8,A1,A2,A0,A3);la quale identifica il display e specifica che deve essere utilizzato a 8 bit se collegato ad arduino uno.
Eseguo la compilazione e mi da il seguente errore:
UTFT_Demo_320x240.ino:31:21: error: expected ')' before numeric constant
Errore durante la compilazione
Da quello che ho capito mi da questo errore perchè non è stato definito il parametro 8 dopo SSD1289 nei define della libreria memorisaver.h ed effettivamente è cosi. Però se lascio la riga già esistente "UTFT myGLCD(ITDB32S,A1,A2,A0,A3);", durante la compilazione mi da comunque errori.
Avete suggerimenti da darmi?
Grazie
Ciao
