Capella CMS

C#.NET merupakan salah satu bahasa pemrograman terbaik, dengan tersedianya IDE yang tepat, Microsoft Visual Studio .NET, menggunakan .NET Framework 2.x

Kali ini kita belajar membaca data dari Serial Port. Pemrograman Serial biasanya dipakai untuk mendapatkan data dari Jembatan Timbang, Timbangan basis Ã¢â‚¬Å“Mini PCÃ¢â‚¬Â dan sejenisnya.

Buatlah class yang menampung semua metode / prosedur membaca, mengolah transaksi timbangan, misalkan kita buat project bernama CapellaUtility, dengan class Utility, seperti code dibawah ini

using System;

using System.Collections.Generic;

using System.Text;

using System.IO;

using System.IO.Ports;

namespace CapellaUtility {

public class Utility {

private static SerialPort port = new SerialPort("COM3",

9600, Parity.None, 8, StopBits.One);

public static Double PortReturnValue;

private static String PortValue;

public static void SerialPort(string PortName, int BaudRate, string ParityType, int ParityBit, string ParityStopBit) {

try {

port.Close();

} catch (Exception ex) {

}

Parity ParityValue = Parity.None;

StopBits ParityStopBits = StopBits.None;

switch (ParityType) {

case "None":

ParityValue = Parity.None;

break;

case "Even":

ParityValue = Parity.Even;

break;

case "Mark":

ParityValue = Parity.Mark;

break;

case "Odd":

ParityValue = Parity.Odd;

break;

case "Space":

ParityValue = Parity.Space;

break;

default:

break;

}

switch (ParityStopBit) {

case "None":

ParityStopBits = StopBits.None;

break;

case "One":

ParityStopBits = StopBits.One;

break;

case "OnePointFive":

ParityStopBits = StopBits.OnePointFive;

break;

case "Two":

ParityStopBits = StopBits.Two;

break;

default:

break;

}

port = new SerialPort(PortName, BaudRate, ParityValue, ParityBit, ParityStopBits);

port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);

}

public static void GetSerialPort() {

try {

port.Close();

} catch (Exception ex) {

}

port.Open();

}

private static void port_DataReceived(object sender, SerialDataReceivedEventArgs e) {

try {

PortValue = port.ReadLine();

if (PortValue.Contains("ST")) {

PortValue = PortValue.Replace("ST", "");

PortValue = PortValue.Replace("GS", "");

PortValue = PortValue.Replace(",", "");

PortValue = PortValue.Replace("+", "");

PortValue = PortValue.Replace("kg", "");

PortValue = PortValue.Replace("\r", "");

PortReturnValue = Convert.ToDouble(PortValue);

}

} catch (Exception ex) {

}

public static string[] GetPortNames() {

return System.IO.Ports.SerialPort.GetPortNames();

}

Kemudian kita buat User Interfacenya sebagai berikut :

File Mainform.cs

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace libramas

{

public partial class MainForm : Form

{

public MainForm()

{

InitializeComponent();

}

private void tiMain_Tick(object sender, EventArgs e)

{

try {

CapellaUtility.Utility.GetSerialPort();

txtBerat.Text = CapellaUtility.Utility.PortReturnValue.ToString();

} catch (Exception ex) {

}

private void btnRun_Click(object sender, EventArgs e)

{

try {

tiMain.Enabled = false;

CapellaUtility.Utility.SerialPort(txtPorts.Text, (int)txtBaudRate.Value,

txtParity.Text, (int)txtBit.Value, txtStopBits.Text);

tiMain.Enabled = true;

} catch (Exception ex) {

}

private void MainForm_Load(object sender, EventArgs e)

{

txtParity.Text = "Even";

txtStopBits.Text = "One";

txtPorts.Items.AddRange(CapellaUtility.Utility.GetPortNames());

if (txtPorts.Items.Count > 0) {

txtPorts.SelectedIndex = 0;

}

File Mainform.resx

<?xml version="1.0" encoding="utf-8"?>

<root>

<!--

Microsoft ResX Schema

Version 2.0

The primary goals of this format is to allow a simple XML format

that is mostly human readable. The generation and parsing of the

various data types are done through the TypeConverter classes

associated with the data types.

Example:

... ado.net/XML headers & schema ...

<resheader name="resmimetype">text/microsoft-resx</resheader>

<resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

<resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

<data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>

<value>[base64 mime encoded serialized .NET Framework object]</value>

</data>

<value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>

<comment>This is a comment</comment>

</data>

There are any number of "resheader" rows that contain simple

name/value pairs.

Each data row contains a name, and value. The row also contains a

type or mimetype. Type corresponds to a .NET class that support

text/value conversion through the TypeConverter architecture.

Classes that don't support this are serialized and stored with the

mimetype set.

The mimetype is used for serialized objects, and tells the

ResXResourceReader how to depersist the object. This is currently not

extensible. For a given mimetype the value must be set accordingly:

Note - application/x-microsoft.net.object.binary.base64 is the format

that the ResXResourceWriter will generate, however the reader can

read any of the formats listed below.

mimetype: application/x-microsoft.net.object.binary.base64

value : The object must be serialized with

: System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

: and then encoded with base64 encoding.

mimetype: application/x-microsoft.net.object.soap.base64

value : The object must be serialized with

: System.Runtime.Serialization.Formatters.Soap.SoapFormatter

: and then encoded with base64 encoding.

mimetype: application/x-microsoft.net.object.bytearray.base64

value : The object must be serialized into a byte array

: using a System.ComponentModel.TypeConverter

: and then encoded with base64 encoding.
