Expander PCF 8574 dekaracja pinów jako define

Kod:
‪#‎include‬ <PCF8574.h>

#include <Wire.h>

// include SPI, MP3 and SD libraries

#include <SPI.h>

#include <Adafruit_VS1053.h>

#include <SD.h>

// --------------------------Chodzi właśnie o te zdefiniowane piny by użyć tych z ekspandera

//‪#‎define‬ CLK 13 // SPI Clock, shared with SD card

#define MISO 12 // Input data, from VS1053/SD card

#define MOSI 11 // Output data, to VS1053/SD card

// Connect CLK, MISO and MOSI to hardware SPI pins. 

// See http://arduino.cc/en/Reference/SPI "Connections"

// These are the pins used for the breakout example

//#define BREAKOUT_RESET 9 // VS1053 reset pin (output)

#define BREAKOUT_CS 10 // VS1053 chip select pin (output)

#define BREAKOUT_DCS 8 // VS1053 Data/command select pin (output)

// These are common pins between breakout and shield

#define CARDCS 4 // Card chip select pin

// DREQ should be an Int pin, see http://arduino.cc/en/Reference/attachInterrupt

#define DREQ 3 // VS1053 Data request, ideally an Interrupt pin
