[英]C# Received data from Arduino
我正在建立一個氣象站,但有一個小問題。 接收到的數據如何在文本框或富文本框中運行? 該應用程序連接了Arduino,但無法讀取數據。
謝謝,
[在此處輸入圖片描述] [1]
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
string InputData = String.Empty;
delegate void SetTextCallback(string text);
public Form1()
{
InitializeComponent();
string[] ports = SerialPort.GetPortNames();
Console.WriteLine("The following serial ports were found:");
// Display each port name to the console.
foreach (string port in ports)
{
comboBox1.Items.Add(port);
}
}
public void guzikpolacz_Click(object sender, EventArgs e)
{
serialPort1.PortName = comboBox1.Text; // Ustawiamy numer Portu COM
// Ustawiamy wartość baudrate portu
//Inne ustawienia zdefiniowane na stałe
serialPort1.Parity = Parity.None; // bez parzystości
serialPort1.StopBits = StopBits.One; // jeden bit stopu
serialPort1.DataBits = 8; // osiem bitów danych
serialPort1.Open();
polestatusu.Text = "Port Otwarty";
polestatusu = SerialPort;
panel1.BackColor = Color.Lime;
guzikpolacz.Enabled = false; //blokujemy przycisk Połącz
guzikrozlacz.Enabled = true;
}
private void guzikrozlacz_Click(object sender, EventArgs e)
{
serialPort1.Close(); //Zamykamy SerialPort
panel1.BackColor = Color.Red;
polestatusu.Text = "Port Zamknięty";
guzikpolacz.Enabled = true; //aktywujemy przycisk Połącz
guzikrozlacz.Enabled = false; // deaktywujemy przycisk Rozłącz
}
private delegate void UpdateUiTextDelegate(string text);
}
}
非常感謝,但不幸的是,它沒有用:(應用程序連接到串行端口,但是什么也沒發生。與Arduino程序Putty的連接有效。

Console.WriteLine("The following serial ports were found:");
// Display each port name to the console.
foreach (string port in ports)

;}
public void guzikpolacz_Click(object sender, EventArgs e)

}
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(new Action(() => serialPort1_DataReceived(sender, e)));
}
else
{
var sp = sender as SerialPort;
//this assumes you want the data from the arduino as text.
// you may need to decode it here.
textBox1.Text = sp.ReadExisting();
}
}
private delegate void UpdateUiTextDelegate(string text);
public Delegate myDelegate { get; set; }
}
}
嘗試將此事件處理程序添加到您的串行端口
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
if (this.InvokeRequired)
{
this.Invoke(new Action(() => serialPort1_DataReceived(sender, e)));
}
else
{
var sp = sender as SerialPort;
//this assumes you want the data from the arduino as text.
// you may need to decode it here.
polestatusu.Text = sp.ReadExisting();
}
}
