我在Windows 7上使用VS2012,它通過以太網連接到我的英特爾伽利略,其草圖使用Arduino 1.5.3上傳。我的最終目標是通過以太網電纜控制電機,但是我無法在兩個程序之間建立簡單的連接。 我沒有以太網或Udp或任何網絡的經驗,所以請詳細說明不合理的數額。試圖通過以太網電纜將英特爾伽利略連接到C#
這裏是我的C#代碼:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace TemperatureArduinoReader
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
byte[] packetData = System.Text.ASCIIEncoding.ASCII.GetBytes("hello World");
string IP = "192.168.1.177";
//"127.0.0.1";
int port = 8888;
IPEndPoint ep = new IPEndPoint(IPAddress.Parse(IP), port);
Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
client.SendTo(packetData, ep);
}
}
}
這是我在Arduino的代碼,從Arduino的webstite採取:
#include <SPI.h> // needed for Arduino versions later than 0018
#include <Ethernet.h>
#include <EthernetUdp.h> // UDP library from: [email protected] 12/30/2008
byte mac[] = { 0X98 , 0x4F, 0xEE, 0x01, 0x54, 0xB3};
IPAddress ip(192,168,1,177);
unsigned int localPort = 8888;
char packetBuffer[UDP_TX_PACKET_MAX_SIZE]; //buffer to hold incoming packet,
char ReplyBuffer[] = "acknowledged"; // a string to send back
// An EthernetUDP instance to let us send and receive packets over UDP
EthernetUDP Udp;
void setup() {
// start the Ethernet and UDP:
Ethernet.begin(mac,ip);
Udp.begin(localPort);
Serial.begin(9600);
}
void loop() {
// if there's data available, read a packet
int packetSize = Udp.parsePacket();
if(packetSize)
{
Serial.print("Received packet of size ");
Serial.println(packetSize);
Serial.print("From ");
IPAddress remote = Udp.remoteIP();
for (int i =0; i < 4; i++)
{
Serial.print(remote[i], DEC);
if (i < 3)
{
Serial.print(".");
}
}
Serial.print(", port ");
Serial.println(Udp.remotePort());
// read the packet into packetBufffer
Udp.read(packetBuffer,UDP_TX_PACKET_MAX_SIZE);
Serial.println("Contents:");
Serial.println(packetBuffer);
// send a reply, to the IP address and port that sent us the packet we received
Udp.beginPacket(Udp.remoteIP(), Udp.remotePort());
Udp.write(ReplyBuffer);
Udp.endPacket();
}
delay(10);
}
首先,我上傳的草圖到伽利略,然後打開串行,然後運行c#程序,但串行中沒有任何內容。
我一直在毆打我的頭靠在一堵牆上試圖弄清楚這幾天。我嘗試過不同的IP地址組合和其他一切,現在我正在尋找你的幫助。
謝謝,馬克
