Sending data to Arduino Uno with Java
提问by cheese5505
I have just bought an Arduino Uno and I am currently trying to make a flashing LED. I was wondering how I could do this, and I have looked at the Arduino Playground and have found a program to get input. I need to output to the Arduino. It is not possible for me to use anything but Java because I already have another program that requires an Arduino. Please leave any ideas.
我刚刚买了一个 Arduino Uno，我目前正在尝试制作一个闪烁的 LED。我想知道如何才能做到这一点，我查看了 Arduino Playground 并找到了一个获取输入的程序。我需要输出到Arduino。我不可能使用 Java 以外的任何东西，因为我已经有另一个需要 Arduino 的程序。请留下任何想法。

EDIT:Kind of sounds like you want to do this in java.
编辑：听起来你想在java中做到这一点。
And excerpt from the sitementioned by jayeff:
The OutputStream comes with 3 different write methods to send data from the computer to the Arduino. In the above example, you could use
output.write(String)to send data, as inoutput.write("Hello Arduino!").
OutputStream 带有 3 种不同的写入方法，可将数据从计算机发送到 Arduino。在上面的示例中，您可以使用
output.write(String)发送数据，如output.write("Hello Arduino!").
If you're trying to use Java to write to the Arduino, then this is your answer.
如果您尝试使用 Java 写入 Arduino，那么这就是您的答案。

EDIT: If you want to use something other than Java, here you go:
编辑：如果您想使用 Java 以外的其他东西，请执行以下操作：
Ask and you shall receive. You can do this in any programming language that has serial support.
问你应接受。您可以使用任何具有串行支持的编程语言执行此操作。
There are certainly other methods for each language, but here are some I found in 5 minutes at the Google Machine
每种语言肯定还有其他方法，但这里有一些我在 5 分钟内在 Google Machine 上找到的
- Perl- Device::SerialPort
- Python- pySerialvia Android Playground
- C++- LibSerial(used below)
- Perl-设备::串行端口
- Python-通过Android Playground 的pySerial
- C++- LibSerial（下面使用）
Note:Watch out for the nasty Auto Reset on Serialissue. See my previous answerfor more details on that.
注意：注意串行问题上令人讨厌的自动重置。有关更多详细信息，请参阅我之前的回答。
Here's my C++ Code (it's ugly but it works)
这是我的 C++ 代码（虽然丑陋但有效）
#include <SerialStream.h>
#include <iostream>
#include <string>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
class SerialComm {
LibSerial::SerialStream myss;
public:
SerialComm(int argc, char** argv) {
myss = new LibSerial::SerialStream("/dev/ttyS0", ios_base::out);
myss.SetBaudRate(LibSerial::SerialStreamBuf::BAUD_57600);
myss.SetCharSize(LibSerial::SerialStreamBuf::CHAR_SIZE_8);
myss.SetFlowControl(LibSerial::SerialStreamBuf::FLOW_CONTROL_NONE);
myss.SetParity(LibSerial::SerialStreamBuf::PARITY_NONE);
myss.SetNumOfStopBits(1);
const int Dsize = 2;
char buffer[1];
buffer[0] = 125; //0b00000001;
buffer[1] = '##代码##';
bitset(buffer[0]);
//myss << buffer;
myss.write(buffer,1);
//myss.Close();
}
}
