I'm trying to make a little weather station that recieves 4 values.
This is the data I get when reading from the serial port:
And I already managed to split it,so I only get the values.
This looks like this:
Now I'ld like to do something with those values (Putting them in graphs, save as CSV, Add comma for temperature, go from hexadecimal to decimal for the pressure,.. ) but I have no idea how I can work with them.
I Was thinking of putting them in an array (undifined rows x 4 columns) or list, but I've no idea how to do that.
Or maybe there is an eaier solution that I have not thinked about.
Here is my code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO.Ports;
using System.IO;
namespace WeatherStation
{
public partial class Form1 : Form
{
private SerialPort port;
public Form1()
{
InitializeComponent();
}
private void btnStart_Click(object sender, EventArgs e)
{
try
{
port = new SerialPort("COM3", 9600, Parity.None, 8);
port.DataReceived += DataReceivedHandler;
port.Open();
}
catch (Exception exc)
{
MessageBox.Show(exc.Message);
}
}
private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
{
try
{
SerialPort sp = (SerialPort)sender;
string data = sp.ReadLine();
string[] ret = data.Split(':');
if (data != String.Empty)
{
Invoke(new Action(() => txtBoxData.AppendText(ret[1] + '\t')))
}
}
catch (Exception exc) //!!
{
MessageBox.Show(exc.Message);
}
}
private void btnStop_Click(object sender, EventArgs e)
{
port.Close();
}
private void btnClear_Click(object sender, EventArgs e)
{
txtBoxData.Clear();
}
private void btnSave_Click(object sender, EventArgs e)
{
try
{
StreamWriter writer = new StreamWriter(#"test.cvs");
writer.Write(txtBoxData.Text);
writer.Close();
}
catch (IOException exc)
{
MessageBox.Show(exc.Message);
}
}
}
}
Thanks in advance for your help
You could store the tag, value, and timestamp as a row in a file. Comma-delimited would probably work.
if (data != String.Empty)
{
string[] ret = data.Split(':');
string text = string.Format("{0:yyyy-MM-dd HH:mm:ss},{1},{2}", DateTime.Now, ret[0], ret[1]);
File.AppendAllText(#"c:\MyFile.csv", text);
}
The above code will add one line per event, to a file named "MyFile.csv". The first column will have the date and time, the second will have the metric type, and the third will have the value.
Once you have added enough lines to the file, you can open it in Excel and make it into a useful table by using the pivot table feature, then create a graph of the data. Or you could load the data into a database and run queries against it.

I am trying to make a program for controlling axis servos but have a small problem with sending values to the Arduino through serial (USB). It seems data don't arrive in the correct format. For purpose of testing, I made a special Arduino code to see what's wrong.
Arduino code:
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
String received;
void loop() {
// put your main code here, to run repeatedly:
if(Serial.available()>0)
{
received=Serial.readString();
}
Serial.println("received: "+received);
}
C# code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.IO.Ports;
using System.Threading;
namespace ServoControl
{
public partial class Form1: Form
{
public Form1()
{
InitializeComponent();
}
SerialPort Sp = new SerialPort();
String AngleX = "0";
String AngleY = "0";
String AngleZ = "0";
String rec = "";
private void Form1_Load(object sender, EventArgs e)
{
Sp.PortName = "COM8";
Sp.BaudRate = 9600;
Sp.DataReceived += Sp_DataReceived;
}
private void Sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
rec=Sp.ReadLine();
}
//when value changed on slider
private void xAxisServo_Scroll(object sender, EventArgs e)
{
if (AngleX!= xAxisServo.Value.ToString())
{
AngleX = xAxisServo.Value.ToString(); valueXaxis.Text = AngleX;
}
if (Sp.IsOpen == true & int.Parse(AngleX) <= 180)
{
Sp.WriteLine(AngleX.ToString());
}
else
{
Sp.Open();
}
}
//when value changed in value box
private void valueXaxis_TextChanged(object sender, EventArgs e)
{
if (int.TryParse(valueXaxis.Text, out int res)==true && int.Parse(valueXaxis.Text)<=180)
{
AngleX = valueXaxis.Text;
xAxisServo.Value = int.Parse(AngleX);
}
if (int.TryParse(valueXaxis.Text, out int res2) == true && int.Parse(valueXaxis.Text) > 180)
{
AngleX = "180";
}
if (Sp.IsOpen == false)
{
Sp.Open();
}
if (Sp.IsOpen == true)
{
Sp.WriteLine(AngleX.ToString());
}
}
private void timer1_Tick(object sender, EventArgs e)
{
textBox1.Text = rec;
}
}
}
I was able to send one value for axis X by function Serial.parseInt(); I was able to read a value from a string in Arduino, but I need to send more than one and I have problem with sending and receiving string.
I have tested a lot with Arduino serial monitor and it seems when sending through builtin monitor in Arduino IDE it works as expected got correct string back, but when using C# checking through textbox1 it shows only received and when not interrupted shows an only bunch of nonsense changing every second.
In reaction to that, I've tried to replace WriteLine with Write because I don't know the background of Arduino very well so I don't how Arduino proceeds data using Serial.readString();.
I've tried to find how builtin serial monitor in Arduino IDE works if in C# or if not in C# at least how are data send.
Any idea why I am getting different results with IDE serial monitor and C#.
Concatenate the Serial.read then add a terminating character to cut the concatenation:
char received;
while(Serial.available()>0)
{
if(received=='#') // put the # in the end of your data
{
Serial.println("received: "+String(received));
break;
}
received+=Serial.read();
}
I made a small gadget with an Arduino that sends 2 values via serial to my c# program (potentiometer value for volume and switch button to change output device). The volume part is already complete but I'm not being able to change between the two output devices (monitor audio and Headphones).
My code at the moment:
using AudioSwitcher.AudioApi.CoreAudio;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Volume
{
public partial class Form1 : Form
{
//msg recieved by serial
String msg;
string[] tokens;
//active device
CoreAudioDevice defaultPlaybackDevice = new CoreAudioController().DefaultPlaybackDevice;
String PHONES = "Headphones (Razer Kraken USB)";
String COLUNA = "ASUS VP228-4 (NVIDIA High Definition Audio)";
public Form1()
{
//open port for serial msg and start timmer
InitializeComponent();
serialPort1.Open();
timer1.Enabled = true;
}
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
//handling of the msg
msg = serialPort1.ReadLine();
tokens = msg.Split('%');
}
private void timer1_Tick(object sender, EventArgs e)
{
label1.Text = tokens[0];
label2.Text = tokens[1];
label6.Text = defaultPlaybackDevice.FullName;
//change volume
defaultPlaybackDevice.Volume = Int32.Parse(tokens[0]);
//change output device
if (tokens[1] == "ON")
{
if (defaultPlaybackDevice.FullName == PHONES)
{
//do nothing
}
else
{
//change to monitor output
}
}
else
{
if (defaultPlaybackDevice.FullName == COLUNA)
{
//do nothing
}
else
{
//change to headphones
}
}
}
}
}
I am using an API called AudioSwitcher.AudioApi.CoreAudio which should allow me to do what I want but I am not being able to find how.
First you need to get all the PlaybackDevices
IEnumerable<CoreAudioDevice> devices = new CoreAudioController().GetPlaybackDevices();
and then you can make a function to change your Default playbackdevice with the fullname like this
private void ChangeOutput(string op)
{
foreach (CoreAudioDevice d in devices)
{
if (d.FullName == op)
d.SetAsDefault();
}
}
I write code to create and connect to VPN using Dotras in C#. It works very good, but when I write code to get connection status, It doesn't work.
I read Dotras document, and write code like example, but It still doesn't work.
It doesn't show status in multiple line textbox. :(
Please show me, what I wrong. Thank you.
Here is my code:

this.handle = this.rasDialer1.DialAsync();
this.btn_disconnect.Enabled = true;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
private void rasDialer1_StateChanged(object sender, StateChangedEventArgs e)
{
this.txt_status.AppendText(e.State.ToString() + "\r\n");
}

{

{

}
else if(e.Connected)
{
this.txt_status.AppendText("Connection successful");
}
else if (e.Error != null)
{
this.txt_status.AppendText(e.Error.ToString());
}
if(!e.Connected)
{
this.btn_disconnect.Enabled = false;
}
}
private void btn_disconnect_Click(object sender, EventArgs e)
{
if(this.rasDialer1.IsBusy)
{
this.rasDialer1.DialAsyncCancel();
}
else
{
RasConnection connection = RasConnection.GetActiveConnectionByHandle(this.handle);
if(connection!=null)
{
connection.HangUp();
}
}
}
}
}
If the events are not firing, the issue might be that the Events are not set in the events section in the properties window of the rasDialer1 control you added to the form (Form1). Using Visual Studio, Enter the design view, click on the rasDialer1 control which reveals the properties of the RasDialer you added, then navigate to events section (marked with a lightening icon) and then set the StateChanged and DialCompleted events.
OR
You can do all this from code simply by
rasDialer.StateChanged += rasDialer1_StateChanged;
rasDialer.DialCompleted += rasDialer1_DialCompleted;
somewhere in the Form1() constructor, where rasDialer1_StateChanged and rasDialer1_DialCompleted are the event handlers in your code.
I'm also anticipating a potential error within your code where accessing UI controls in those event handlers will get you a Cross-thread operation not valid error since they are called from an async operation this.rasDialer1.DialAsync();
The right way of accessing controls from methods called from another thread is below ...
textbox1.Invoke(new Action(() => textbox1.text = "my string"));
Try using dial instead of dialAsync
try:
{
File.WriteAllText("your rasphone.pbk path","")//Add
string vpnuser = txt_vpn_user.Text;
string ip_address = txt_IP.Text;
this.rasPhoneBook1.Open();
RasEntry entry = RasEntry.CreateVpnEntry(vpnuser, ip_address, RasVpnStrategy.Default, RasDevice.GetDeviceByName("(PPTP)", RasDeviceType.Vpn, false));
this.rasPhoneBook1.Entries.Add(entry);
MessageBox.Show("Success");
}
I'm trying to make GUI for my arduino analogread. The GUI display graph and text line of the value that arduino read. I'm using zedgraph for graphing.
I need to write "on" in the serial monitor window of arduino to start the readings. it runs well. But when I try to control via GUI I made with C# Visual
Studio, the reading won't start. it says "Access to the port 'COM3' is denied".
Here's my arduino code:
void loop() {
while (Serial.available() > 0)
{
input += (char) Serial.read(); // Read in one char at a time
delay(5);
} if (input == "on")
{
myservo.write(0);
---analog reading and Serial.println arduino---
} if (input == "off")
{
myservo.write(115);
}
}
And this is my visual studio code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using ZedGraph;
using System.IO.Ports;
using System.Globalization;
namespace concentrationMeasurement
{
public partial class Form1 : Form
{
private SerialPort myport;
private DateTime datetime;
private string in_data;
public Form1()
{
InitializeComponent();
}
private void btnStart_Click(object sender, EventArgs e)
{
myport = new SerialPort();
myport.BaudRate = 115200;
myport.PortName = port_name.Text;
myport.Parity = Parity.None;
myport.DataBits = 8;
myport.StopBits = StopBits.One;
myport.DataReceived += myport_DataReceived;
try
{
myport.Open();
myport.WriteLine("on");
data_tb.Text = "";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message,"Error");
}
}
private void myport_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
in_data = myport.ReadLine();
this.Invoke(new EventHandler(displaydata_event));
}
private void displaydata_event(object sender, EventArgs e)
{
datetime = DateTime.Now;
string time = datetime.Hour + ":" + datetime.Minute + ":" + datetime.Second;
data_tb.AppendText(time + "\t\t" + in_data + "\n");
}
private void btnStop_Click(object sender, EventArgs e)
{
try
{
myport.Close();
}
catch (Exception ex2)
{
MessageBox.Show(ex2.Message, "Error");
}
}
private void save_btn_Click(object sender, EventArgs e)
{
try{
string pathfile = #"C:\Users\ajis.aprl\Documents\TA bgt\data_GUI\";
string filename = "concentration.txt";
System.IO.File.WriteAllText(pathfile + filename, data_tb.Text);
MessageBox.Show("Data has been saved to "+pathfile,"Save File");
}
catch (Exception ex3){
MessageBox.Show(ex3.Message, "Error");
}
}
private void Form1_Load(object sender, EventArgs e)
{
plotGraph();
SetSize();
}
private void plotGraph()
{
GraphPane myPane = zedGraphControl1.GraphPane;
myPane.Title.Text = "Concentration Growth";
myPane.XAxis.Title.Text = "time";
myPane.YAxis.Title.Text = "concentration";
}
}
}
So I got 2 problem here:
As I said, I can't run my analog reading via GUI, it says "Access to the port 'COM3' is denied".
in myPane.Title.Text, myPane.XAxis.Title.Tex, and myPane.YAxis.Title.Text, there's error in "Text" it says:
"Error 3 'string' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?)"
I googled everywhere but I can't find the answer. Please if anyone know what I'm missing. Can you tell me what's wrong with my code/logic? Thank you.
