控制与Java一个Arduino [英] Control an Arduino with Java

问题描述

我期待把一个 LED和关闭Java程序。我没有在C＃项目大致5分钟，但它似乎是有些在Java中更具挑战性。我有Arduino的等待一个1或0将被写入到 COM端口以及将改变LED基于这一点。在code我使用的Arduino是如下：

I am looking to turn an LED on and off with a Java program. I did the project in C# in roughly 5 minutes, but it seems to be somewhat more challenging in Java. I had the Arduino wait for a 1 or 0 to be written to the COM port and would change the LED based on that. The code I am using for the Arduino is as follows.

int LedPin = 13;
char data;

void setup()
{
    Serial.begin(9600);
    pinMode( LedPin , OUTPUT );
}

void loop()
{
    data = Serial.read();
    if (Serial.available() > 0)
    {
        if(data == '1' )
        {
            digitalWrite(LedPin,HIGH);
        }
        else if(data == '0' )
        {
            digitalWrite(LedPin,LOW);
        }
    }
    else
        if (Serial.available()<0)
        {
            digitalWrite(LedPin,HIGH);
            delay(500);
            digitalWrite(LedPin,LOW);
            delay(500);
        }
}

我将如何做到这一点有一个Java应用程序？

How would I do this with a Java application?

推荐答案

您可以使用JArduino（Java的Arduino的）库，它提供了一个Java API使用串行端口来控制你的Arduino（使用USB电缆或无线设备从软件的角度来看），UDP（通过以太网盾）表现为串行端口。所有涉及到Java和Arduino的之间的通信code是由库内部管理。

You can use the JArduino (Java-Arduino) library, which provides a Java API to control your Arduino using serial port (using a USB cable, or wireless devices behaving as serial ports from a software point of view), UDP (via an ethernet shield). All the code related to communication between Java and Arduino is managed internally by the library.

public class Blink extends JArduino {

public Blink(String port) {
    super(port);
}

@Override
protected void setup() {
    // initialize the digital pin as an output.
    // Pin 13 has an LED connected on most Arduino boards:
    pinMode(DigitalPin.PIN_12, PinMode.OUTPUT);
}

@Override
protected void loop() {
    // set the LED on
    digitalWrite(DigitalPin.PIN_12, DigitalState.HIGH);
    delay(1000); // wait for a second
    // set the LED off
    digitalWrite(DigitalPin.PIN_12, DigitalState.LOW);
    delay(1000); // wait for a second
}

public static void main(String[] args) {
    String serialPort;
    if (args.length == 1) {
        serialPort = args[0];
    } else {
        serialPort = Serial4JArduino.selectSerialPort();
    }
    JArduino arduino = new Blink(serialPort);
    arduino.runArduinoProcess();
}
}
