Original: WPF implementation and serial port to send data and receive data
< svg xmlns="http://www.w3.org/2000/svg" style="display: none;">
Send data and receive with serial port Data, here is a simple demo. This demo can realize pressing the hardware button, the light is on, and the light status data is sent. And several lights can be turned on at the same time, and the status data of the lights can be sent over. On the PC side, click the button to make the hardware light on.
Here are 4 lights, the data sent over: 0 means dark, 1 means bright. For example: 1010 means that the 1st and 3rd lights are on, and the 2nd and 4th lights are dim.
Send the past data: 0 means light 1 is on, 1 means light 1 is off, 2 means light 2 is on, 3 means light 2 is off, 4 means light 3 is on, 5 means light 3 is off, 6 is 4 No. light is on, 7 means No. 4 light is off.
Layout code:
<Grid>
<TextBox HorizontalAlignment="Left" Height="23" Margin="112,59,0,0" TextWrapping="Wrap" Name= "txtSend" VerticalAlignment="Top" Width="120 "/>
<TextBox HorizontalAlignment="Left" Height="23" Margin="112,113,0,0" TextWrapping="Wrap" Name="txtReceive" VerticalAlignment="Top" Width="120"< /span>/>

Background code:
First
private SerialPort Sp = new SerialPort();
public delegate void HandleInterfaceUpdataDelegate(string text);
private HandleInterfaceUpdataDelegate interfaceUpdataHandle;
String[] arr = {"0", "0", "0", "0" };//used to store the status of the lights on the hardware span>
Secondly, add a parameter for changing the serial port in the Loaded event:
//change the parameter
Sp.PortName = "COM3";
Sp.BaudRate = 115200;
Sp.Parity = Parity.None;
Sp.StopBits = StopBits.One;
Write monitoring and sending data events:
private void Serial()
{
Sp.DataReceived += new SerialDataReceivedEventHandler(Sp_DataReceived);
if (!Sp.IsOpen)
{
Sp.Open();
}
//Send data in bytes
SendBytesData(Sp);
}
//Send binary data
private void SendBytesData(SerialPort Sp)
{
byte[] bytesSend = System.Text.Encoding.Default.GetBytes(txtSend.Text);
Sp.Write(bytesSend, 0, bytesSend.Length);
}
public void Sp_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
/* byte[] readBuffer = new byte[Sp.ReadBufferSize]; Sp.Read(readBuffer, 0, readBuffer.Length); //Dispatcher.Invoke(interfaceUpdataHandle, new string[] {Encoding.UTF8.GetString(readBuffer)}); Dispatcher.Invoke(interfaceUpdataHandle, new string[] {Encoding.ASCII.GetString(readBuffer) }); //Dispatcher.Invoke(interfaceUpdateHandle, new string[] {Encoding.ASCII .GetString(buf) });*/
SerialPort serialPort = (SerialPort)(sender);
System.Threading.Thread.Sleep(100);//Delay for a while to prevent the hardware sending rate from not keeping up Cached data clutter caused by cached data
int n = serialPort.BytesToRead;//Write it down first to avoid certain reasons, man-made reasons, and operate several times Long time, inconsistent cache
byte[] buf = new byte[ n];//Declare a temporary array to store the current serial port data
//received_count += n;//Increase the received count
serialPort.Read(buf, 0, n);//Read buffered data
//Because you want to access ui resources, you need to use invoke to synchronize ui
interfaceUpdataHandle = new HandleInterfaceUpdataDelegate(UpdateTextBox);//Instantiate the delegate object
// Dispatcher.Invoke(interfaceUpdateHandle, new string[] {Encoding.ASCII.GetString(buf) });
Dispatcher.Invoke(interfaceUpdataHandle, new string[] {Encoding.ASCII.GetString(buf) });
//serialPort.Close();
}
private void UpdateTextBox(string text)
{
txtReceive.Text = text;
String Receive = Convert.ToString(text);
if (Receive != "")
{
// MessageBox.Show("receive", Receive);
String Receive1 = Receive.Substring(0, 1);
String Receive2 = Receive.Substring(1, 1);
String Receive3 = Receive.Substring(2, 1);
String Receive4 = Receive.Substring(3, 1);
if (Receive1 == 1.ToString())
{
one.Background = new SolidColorBrush(Colors.MediumAquamarine);
arr[0] = 1.ToString();
}
else
{
one.Background = new SolidColorBrush(Colors.Red);
arr[0] = 0.ToString();
}
if (Receive2 == 1.ToString())
{
two.Background = new SolidColorBrush(Colors.MediumAquamarine);
arr[1] = 1.ToString();
}
else
{
two.Background = new SolidColorBrush(Colors.Red);
arr[1] = 0.ToString();
}
if (Receive3 == 1.ToString())
{
three.Background = new SolidColorBrush(Colors.MediumAquamarine);
arr[2] = 1.ToString();
}
else
{
three.Background = new SolidColorBrush(Colors.Red);
arr[2] = 0.ToString();
}
if (Receive4 == 1.ToString())
{
four.Background = new SolidColorBrush(Colors.MediumAquamarine);
arr[3] = 1.ToString();
}
else
{
four.Background = new SolidColorBrush(Colors.Red);
arr[3] = 0.ToString();
}
//String abc = Convert.ToString(arr);
//MessageBox.Show("abc", abc);
// MessageBox.Show("arr", arr);
}
}
Add the last button click event:
private void btnSend_Click(object sender, RoutedEventArgs e)
{
if (arr[0] == 0.ToString())
{
txtSend.Text = "0";
Serial();
}
else
{
txtSend.Text = "1";
Serial();
}
}
private void btnSend1_Click(object sender, RoutedEventArgs e)
{
if (arr[1] == 0.ToString())
{
txtSend.Text = "2";
Serial();
}
else
{
txtSend.Text = "3";
Serial();
}
}
private void btnSend2_Click(object sender, RoutedEventArgs e)
{
if (arr[2] == 0.ToString())
{
txtSend.Text = "4";
Serial();
}
else
{
txtSend.Text = "5";
Serial();
}
}
private void btnSend3_Click(object sender, RoutedEventArgs e)
{
if (arr[3] == 0.ToString())
{
txtSend.Text = "6";
Serial();
}
else
{
txtSend.Text = "7";
Serial();
}
}
If you want to monitor the data at the beginning of the program, add it to Loaded: Serial();

最后button点击事件添加：

{

Serial();
}
else
{

Serial();

else
{

Serial();
}

{

Serial();

else
{

Serial();
}

private void btnSend3_Click(object sender, RoutedEventArgs e)
{
if (arr[3] == 0.ToString())
{
txtSend.Text = "6";
Serial();
}
else
{
txtSend.Text = "7";
Serial();
}
}
要想在程序开始时就可以监听数据，在其Loaded里面添加上： Serial();

这样可以实现btn和硬件本身按钮同时控制灯亮灯灭。若转载请注明转载处。
