Hello Everyone
I have a board attached with some sensors.I need to perform these steps.
1:.Send some commands to microcontroller and then read the data after sending each command.
2:. Then I have to do some calculations on received data and then saved it in to a text file.
I am stuck at data read from Serial Port.
I know how to write data but I don't know how to call data read event every time(after sending different commands to microcontroller).
Here is my code.Your help will be appreciated.
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;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
comboBox1.Items.AddRange(SerialPort.GetPortNames());
serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived);
}
private void button1_Click(object sender, EventArgs e)
{
serialPort1.PortName = comboBox1.Text;
serialPort1.Open();
serialPort1.Write("$g helloboard!");
}
string abc;
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
int bytes = serialPort1.BytesToRead;
byte[] buffer = new byte[16];
serialPort1.Read(buffer, 0, 16);
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
abc = enc.GetString(buffer);
}
}
}
