I have 3 classes:



  • Sensor: reads data continously from serial port and parses it. When data is parsed, adds it to blockingCollection


  • DataProcessing: Gets the data from blockingCollecion and process it.


  • DisplayDataForm: Displays processed data


How can I make sure, DataProcessing runs continously but not blocking and when new data arrives and its processed is displayed in the form?



class Sensor

public BlockingCollection<double[]> _bufferTimeSeriesData;

public void serialPort_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)

byte[] buffer = new byte[_serialPort1.BytesToRead];
lock (buffer)

_serialPort1.Read(buffer, 0, buffer.Length);

double[] samplesAtTimeT;
for (int i = 0; i < buffer.Length; i++)

samplesAtTimeT = _BinaryStreamConverter.interpretBinaryStream(buffer[i]);
if (samplesAtTimeT != null)
_bufferTimeSeriesData.Add(samplesAtTimeT); //This is the BlockingCollection

_bufferTimeSeriesData.CompleteAdding();




class DataProcessing

public void ProcessData()

Task.Run(() =>

while (Globals.Sensor._bufferTimeSeriesData.IsCompleted)

double[] samplesAtTimeT = Globals.Sensor._bufferTimeSeriesData.Take();

//Process data

// writes data to file (is it correct to do it here?)

// Send processed data to form to plot in a chart. HOW??






class DisplayForm:Form

public void DisplayDataInForm(double[] samples)

chartCh1.Series["Signal"].Points.Add(samples[1]);
chartCh2.Series["Signal"].Points.Add(samples[2]);

while (chartCh1.Series["Signal"].Points.Count > 1000)

chartCh1.Series["Signal"].Points.Remove(chartCh1.Series["Signal"].Points.First());
chartCh2.Series["Signal"].Points.Remove(chartCh2.Series["Signal"].Points.First());
