如何使用Arduino从C＃读取数据 [英] How Do I Read Data Send From C# With Arduino

问题描述

我仍然是C＃和arduino的新手，我没能看到我在串口监视器上从c＃发送的数据。以下是我的代码...：

Arduino：

  #include   <   EEPROM.h  >  
   #include   <   SoftwareSerial.h  >  
  SoftwareSerial xbee（ 2 ， 3 ）; 
  int 传入; 
  int   id ; 
  int  rea; 
  int  comp = 0; 
  void  setup（）{
 Serial.begin（ 9600 ）; 
 xbee.begin（ 9600 ）; 
} 
 
  void  loop（）{
  if （Serial.available（））
 {
 Serial.print（  hhhh）; 
  id  = Serial.read（）; 
 incoming = Serial.read（）; 
  if （id！= '  New' ）
 {
 xbee.println（ id ）; 
 xbee.println（来电）; 
 EEPROM.write（ id ，incoming）; 
 rea = EEPROM.read（ id ）; 
 Serial.print（ id ）; 
} 
  else  
 {
 EEPROM.write（comp，incoming）; 
 rea = EEPROM.read（ id ）; 
 Serial.print（ id ）; 
 comp + = 1; 
} 
} 
} 

C＃：

  protected   void  Button7_Click（ object  sender，EventArgs e）
 {
 {
 SerialPort comPort =  new  SerialPort（  COM3， 9600 ，Parity.None， 8 ，StopBits.One）; 
 尝试 
 {
 comPort.Open（）; 
 comPort.Write（TextBox1.Text）; 
 comPort.Write（ 删除）; 
 comPort.Close（）; 
} 
  catch （UnauthorizedAccessException ex）
 {
 Response.Write（ 错误： + ex.ToString（））; 
} 
 尝试 
 {
 OleDbConnection conn =  new  OleDbConnection（  Provider = Microsoft.Jet.OLEDB.4.0; Data Source = + Server.MapPath （  App_Data \\Stock.mdb））; 
 conn.Open（）; 
  Int32  ash = Convert.ToInt32（TextBox1.Text）; 
  string  deleteQuery =  从Instock中删除ID =' + ash +  '; 
 OleDbCommand com =  new  OleDbCommand（deleteQuery，conn）; 
 com.ExecuteNonQuery（）; 
 Response.Write（ 项目已成功删除）; 
 Response.Redirect（  UpdateDB.aspx）; 
 conn.Close（）; 
} 
  catch （例外情况）
 {
 Response.Write（ 错误： + ex.ToString（））; 
} 
} 
}

Arduino，C＃和串行接口 [ ^

am still new in C# and arduino, am failing to see the data i send from c# on serial monitor. below are my codes...:
Arduino:

#include <EEPROM.h>
#include <SoftwareSerial.h>
SoftwareSerial xbee(2, 3);
int incoming;
int id;
int rea;
int comp=0;
void setup() {
  Serial.begin(9600);
  xbee.begin( 9600 );
 }

void loop() {
  if(Serial.available())
   {
     Serial.print("hhhh");
     id = Serial.read();
     incoming = Serial.read();
     if(id!='New')
     {
     xbee.println(id);
     xbee.println(incoming);
     EEPROM.write(id, incoming);
     rea = EEPROM.read(id);
     Serial.print(id);
    }
    else
     {
      EEPROM.write(comp, incoming);
      rea = EEPROM.read(id);
      Serial.print(id);
      comp+=1;
     }
   }
}

C#:

protected void Button7_Click(object sender, EventArgs e)
        {
            {
                SerialPort comPort = new SerialPort("COM3", 9600, Parity.None, 8, StopBits.One);
                try
                {
                    comPort.Open();
                    comPort.Write(TextBox1.Text);
                    comPort.Write("Delete");
                    comPort.Close();
                }
                catch (UnauthorizedAccessException ex)
                {
                    Response.Write("Error:" + ex.ToString());
                }
                try
                {
                    OleDbConnection conn = new OleDbConnection("Provider= Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("App_Data\\Stock.mdb"));
                    conn.Open();
                   Int32 ash = Convert.ToInt32(TextBox1.Text);
                    string deleteQuery = "delete from Instock where ID= '" + ash + "'";
                    OleDbCommand com = new OleDbCommand(deleteQuery, conn);
                    com.ExecuteNonQuery();
                    Response.Write("Item deleted successfully");
                    Response.Redirect("UpdateDB.aspx");
                    conn.Close();
                }
                catch (Exception ex)
                {
                    Response.Write("Error:" + ex.ToString());
                }
            }
        }
