brauchen Hilfe int array von C# senden zu Arduino

Question

Ich habe folgende integer array [1,2,3,4,5,6,7,8,9]

Ich brauche es zu senden UNO Arduino .

Ich habe versucht, es als Array von Byte zu senden, aber es funktioniert nicht.

C# -Code:

using System.IO.Ports; 

private void Form1_Load(object sender, EventArgs e) 
{serialPort1.Open();} 

byte[] OUT = { 1,2,3,4,5,6,7,8,9 }; 

serialPort1.Write(OUT, 0, 12); 

Arduino Code

void setup() { 

    Serial.begin(9600); 

    for (byte aPin = start; aPin <= 13 ; aPin++) { 
    pinMode(aPin, OUTPUT);} 

    for (byte apin = start; apin <= 13 ; apin++) { 
    digitalWrite(apin,HIGH);} 


} 


void loop(){ 

//Serial communication step 
//Serial.write("6564456464646"); 

if(Serial.available()){ 

    for(char j=0;j<Serial.available();j++) 
    {input[j]=Serial.read();}

Answer 2

Sie diesen Teil für C# Teil verwenden:

  Connect(); 
     if (serialPort1.IsOpen) 
     { 
      int MyInt = ToInt32(lblFirstNumber.Text); 
      byte[] b = GetBytes(MyInt); 
      serialPort1.Write(b, 0, 1); 

      int MyInt2 = ToInt32(txtFirstNumber.Text); 
      byte[] z = GetBytes(MyInt2); 
      serialPort1.Write(z, 0, 1); 

      int MyInt3 = ToInt32(txtSecondNumber.Text); 
      byte[] p = GetBytes(MyInt3); 
      serialPort1.Write(p, 0, 1); 

      serialPort1.Close(); 
     } 
     else 
     { 
      MessageBox.Show("Please control your connection"); 
     }
