Errore con "spaccatura" programma

Salve, sto facendo un passo avanti, o meglio sto cercando di farlo, e di creare per bene gli header ed i file cpp per le varie classi. Ecco un estratto:

File .INO

// Debug variable
#define DEBUG;

#include "VariableDefinitions.h"
#include "EEPROMHandler.h"
#include "SplahScreenPage.h"
#include "MainPage.h"
#include "SetupPage.h"
#include "SetValuesPage.h"
#include "DinamicChartFrame.h"

DinamicChartFrame.h:

#ifndef DINAMICCHARTFRAME_H_
#define DINAMICCHARTFRAME_H_

//#define CHART_DEBUG

class DinChart {
public:
	void drawChart(int roomIndex, double value);
	void clearChartArea(int roomIndex);
	void handleDinamicChart(int roomIndex);
};

#endif /* DINAMICCHARTFRAME_H_ */

Estratto del file

DinamicChartFrame.cpp:

#include "DinamicChartFrame.h"

void DinChart::handleDinamicChart(int roomIndex) {

	// Checks if the maximum value for Y axis has changed
	if (roomPV[roomIndex] > chartMaxY[roomIndex]) {
		isAxisRefreshNeeded[roomIndex] = true;
		chartMaxY[roomIndex] = round(roomPV[roomIndex]) + 1;
		isChartRefreshNeeded[roomIndex] = true;
	}

	// Draw axes
	if (isAxisRefreshNeeded[roomIndex] || isChartRefreshNeeded[roomIndex]) {
		isAxisRefreshNeeded[roomIndex] = false;
		isChartRefreshNeeded[roomIndex] = false;
//		display.setColor(VGA_AQUA);
		display.drawHLine(CHART_FRAME_X1 + CHART_FRAME_OFFSET * (roomIndex),

Il problema sorge nel momento in cui nel file .INO dichiaro l'oggetto di tipo DinChart e poi tento di istanziarlo:

	DinChart newChart;
.
.
.
.
.
	// Draws chart if requested
	if (mainWindow)
		for (int chartIndex = 0; chartIndex <= 1; chartIndex++) {
			if (isRoomActive[chartIndex] && roomCreateChart[chartIndex])
				newChart.handleDinamicChart(chartIndex);
		}

Ottengo il seguente errore in compiazione:

Cioè so che ho sbagliato una scemenza ma non ci arrivo mica eh....boh, sarà l'età forse?
