我是netduino的新手，所以我有一個簡單的問題（或者它應該很簡單）。 我想做的是從我的winform應用程序發送一個整數（字符串）從我的winform應用程序到我的netduino加2，然後，我的netduino應該讀取該整數，並在板上多次閃爍。與PC的Netduino通信
我已閱讀過該主題的在線教程，並找到了一些應該提供我的PC和Netduino之間通信的示例。
是的，我確實收到了迴音。即使斷開我的netduino並將其隱藏在我的口袋裏，我也會收到回聲:)。 對於我對該小工具的理解非常多。
如何通過rs232電纜將信息發送至我的Netduino，以便他可以閱讀，理解並採取相應措施？
有一個代碼，直接從網頁：
對於NETDUINO：
using System;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using SecretLabs.NETMF.Hardware;
using SecretLabs.NETMF.Hardware.Netduino;
using System.IO.Ports;
namespace NetduinoApplication1
{
public class Program
{
static SerialPort serial;
public static void Main()
{
// initialize the serial port for COM1 (using D0 & D1)
serial = new SerialPort(SerialPorts.COM1, 9600, Parity.None, 8, StopBits.One);
// open the serial-port, so we can send & receive data
serial.Open();
// add an event-handler for handling incoming data
serial.DataReceived += new SerialDataReceivedEventHandler(serial_DataReceived);
OutputPort led = new OutputPort(Pins.ONBOARD_LED, false);
for (int i = 0; i < 3; i++)
{
led.Write(true); // turn on the LED
Thread.Sleep(250); // sleep for 250ms
led.Write(false); // turn off the LED
Thread.Sleep(250); // sleep for 250ms
}
// wait forever...
Thread.Sleep(Timeout.Infinite);
}
static void serial_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// create a single byte array
byte[] bytes = new byte[1];
// as long as there is data waiting to be read
while (serial.BytesToRead > 0)
{
// read a single byte
serial.Read(bytes, 0, bytes.Length);
// send the same byte back
serial.Write(bytes, 0, bytes.Length);
OutputPort led1 = new OutputPort(Pins.ONBOARD_LED, false);
led1.Write(true); // turn on the LED
Thread.Sleep(250); // sleep for 250ms
led1.Write(false); // turn off the LED
Thread.Sleep(250); // sleep for 250ms
}
}
}
}
而對於我的控制檯代碼：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Ports;
namespace ConsoleRSS
{
class Program
{
static SerialPort serial;
static void Main(string[] args)
{
// provide some usage information
System.Console.WriteLine("enter some text and hit ENTER.");
System.Console.WriteLine("enter 'x' and hit ENTER to exit.");
System.Console.WriteLine();
// initialize the serial port for COM3 (could be other port, depends on system)
serial = new SerialPort("COM3", 9600, Parity.None, 8, StopBits.One);
// open the serial-port, so we can send & receive data
serial.Open();
// add an event-handler for handling incoming data
serial.DataReceived += new SerialDataReceivedEventHandler(serial_DataReceived);
// this will hold each line entered
string line = string.Empty;
// as long as an x is not entered
while (line.ToLowerInvariant() != "x")
{
// read a single line from the console
line = System.Console.ReadLine();
// convert the line to bytes
byte[] utf8Bytes = System.Text.Encoding.UTF8.GetBytes(line);
// send the bytes over the serial-port
serial.Write(utf8Bytes, 0, utf8Bytes.Length);
}
}
static void serial_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// wait a little for the buffer to fill
System.Threading.Thread.Sleep(100);
// create an array for the incoming bytes
byte[] bytes = new byte[serial.BytesToRead];
// read the bytes
serial.Read(bytes, 0, bytes.Length);
// convert the bytes into a string
string line = System.Text.Encoding.UTF8.GetString(bytes);
// write the received bytes, as a string, to the console
System.Console.WriteLine("echo: " + line);
System.Console.WriteLine();
}
}
}
你可以顯示一些你嘗試過的東西的代碼嗎？這是你嘗試過的例子嗎？ http://www.instructables.com/id/Serial-Port-Programming-With-NET/ – tay10r
也許你和這篇文章的作者：http://stackoverflow.com/questions/16623915/how-to-send- a-signal-to-run-a-machine-using-netduino should talk :)很相似的問題...... – user2019047
