[英]C# Received data from Arduino
I'm building a weather station and I have a little problem. 我正在建立一个气象站,但有一个小问题。 How do the received data to run at a textbox or rich box?
接收到的数据如何在文本框或富文本框中运行? The application connects Arduino, but does not operate to read data.
该应用程序连接了Arduino,但无法读取数据。
Thank you, 谢谢,

// Display each port name to the console.

serialPort1.DataBits = 8; // osiem bitów danych
serialPort1.Open();

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

Thank you very much, but unfortunately it did not work :( The application connects to the serialport but nothing happens. The connection to the Arduino program Putty works. 非常感谢,但不幸的是,它没有用:(应用程序连接到串行端口,但是什么也没发生。与Arduino程序Putty的连接有效。

try adding this event handler to your serial port 尝试将此事件处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)));
