Emon and SerLCD

OK I will try what you said when I get home.

Do I use you code like the following example?

void loop()
{
  emon1.calcVI(20,2000);         // Calculate all. No.of wavelengths, time-out

  mySerial.write(254); // cursor to 4th position on first line
  mySerial.write(131);
 
  mySerial.print(emon1.getVrms()); // write out the VAC value

  mySerial.write(254); // cursor to 4th position on second line
  mySerial.write(195);

  mySerial.write(emon1.getIrms()); // write out the AAC value

  mySerial.write(254); // cursor to 4th position on second line
  mySerial.write(204);

  mySerial.write(emon1.getApparentPower()); // write out the AAC value
    
  delay(1000); // short delay
}

You said that the 5 values are private but these are located above the keyword private: aren't they public then?

This part is public:

public:

    void voltage(int _inPinV, double _VCAL, double _PHASECAL);
    void current(int _inPinI, double _ICAL);

    void voltageTX(double _VCAL, double _PHASECAL);
    void currentTX(int _channel, double _ICAL);

    void calcVI(int wavelengths, int timeout);
    double calcIrms(int NUMBER_OF_SAMPLES);
    void serialprint();

    long readVcc();
    //Useful value variables
    double realPower,
       apparentPower,
       powerFactor,
       Vrms,
       Irms;

And this part is private:

  private:

    //Set Voltage and current input pins
    int inPinV;
    int inPinI;
    //Calibration coeficients
    //These need to be set in order to obtain accurate results
    double VCAL;
    double ICAL;
    double PHASECAL;

    //--------------------------------------------------------------------------------------
    // Variable declaration for emon_calc procedure
    //--------------------------------------------------------------------------------------
	int lastSampleV,sampleV;   //sample_ holds the raw analog read value, lastSample_ holds the last sample
	int lastSampleI,sampleI;                      

	double lastFilteredV,filteredV;                   //Filtered_ is the raw analog value minus the DC offset
	double lastFilteredI, filteredI;                  

	double phaseShiftedV;                             //Holds the calibrated phase shifted voltage.

	double sqV,sumV,sqI,sumI,instP,sumP;              //sq = squared, sum = Sum, inst = instantaneous

	int startV;                                       //Instantaneous voltage at start of sample window.

	boolean lastVCross, checkVCross;                  //Used to measure number of times threshold is crossed.
	int crossCount;                                   // ''
