Error creating .elf

Projects Programming

I have a class that contains an array of [8][1440] for a total of 11,520 bytes. I'm using a Mega2560. When I change the array to static, I get the error "Error creating .elf". I'm very new to Arduino. What am I doing wrong and how can I fix it? Here is the .h class file:

// MainValves.h

#ifndef _MAINVALVES_h
#define _MAINVALVES_h

#if defined(ARDUINO) && ARDUINO >= 100
  #include "Arduino.h"
#else
  #include "WProgram.h"
#endif

class MainValvesClass
{
 protected:  
  static char valveArray[8][1440];
  
 public:  
  void init();
  void SetValveData(int, int, int, int);
  bool GetValveStatus(int day, int valve, int minute);
};

extern MainValvesClass MainValves;
#endif

That's going to be a problem on a Mega. You just don't have enough RAM to deal with that. If the array is a static lookup table, you can put it in PROGMEM. If it has to be RAM, it simply won't fit. You may be able to get it down to one or two bits per valve. Then it would be something like 1.4-2.8K and would fit in a Mega's RAM. (just)
