I have been scouring the internet for some time now trying to figure out how to send data from C++ (which will read an input .txt file) to an Arduino. Because there does not seem to be a native way in Arduino to read files directly, I chose to use C++ to read the file and then send it over to the Arduino. The primary method of doing this seems to be communicating via Serial. So my question is this:
How do you communicate to Serial in C++ (using an OS X device) and subsequently read it in Arduino? Further, are there other, simpler methods of transferring data to Arduino via C++ or natively in Arduino?
Take a look at boost asio or Qt Serial Port.
Both are portable versions for serial-communication with C++.
There is no other option, which could be simpler than serial communication.

So I am in a bit of a dilemma, I want to create a LED dashboard using my Raspberry Pi, the only problem is how am I going to read the data to the Raspberry Pi using C++? I am thinking about buying an OBD to USB connector and reading the data from there, but it still doesn't change the fact that I would need parse the data, but the only library I found for OBD on C++ is https://github.com/lkrasner/obd-cxx but it does not look promising.
So this is where I turn to the Stack Overflow community to help me out because I have run out of options.
Can the OBD data be read as serial? If it was serial, wouldn't that be too slow for a real-time speedometer? Should I use another port instead of OBD?
I have quickly searched and found this topic: http://blog.lemberg.co.uk/how-guide-obdii-reader-app-development
It is not usb, but it tels about AT commands to communicate with the adaptor. Thus, I would assume the USB one will be visible as a serial interface with the same communication principle. Then you might not need a library, as you can directly read-write your serial device.
Make sure only, that the adaptor you're gonna buy supports the communication protocol of your car (CAN or another). Perhaps also one option to think about is whether the adaptor provides high-level commands for you (then you need to check that the required diagnostics services are supported by the adaptor), or you need to build/parse the raw diagnostic messages yourself (I think this would be more flexible solution).
i have a board and a GPS,accelerometer,gyroscope onboard.
I'm connecting the board to the computer by using a TTL-232R-3V3 ,which is a USB to TTL Serial Cable (3.3V).
After installing the drivers, the assigned COM port is the number 3.
I'm able to read the output simply by using a serial monitor (i've tried with the one included in the Arduino IDE, just for try).
Now i need to create a C++ program which allows me to take the output of the board and store the datas in vectors.
Do i need any libraries? What's the best procedure to do it?
Thanks in advance!
In my company I used the boost library to read from a COM port. It includes the boost::asio::serial_port class to handle this kind of communication.
I used this code snippet for orientation and wrote my own wrapper class, for the needs of the project I was in.
You can take this:

Or if you use Qt, i think there is also a lib from Qt to do this.
I want to control my arduino board by my own c++ or java programme. Basically I want to get values from arduino. And perform some tasks based on that values. Simply,I have connected a potentiometer to arduino and I want to read its value in my programme.
You can use the telecommand to control the arduino from your pc. pc will send a string, and a program for the control of the input string on arduino
Your question is very broad so its difficult to give a direct answer, but the normal way is to use serial coms via a USB cable. In your Arduino code use either Serial or SoftwareSerial to open a connection. In your C++ application you will open a connection to the same COM port your Arduino is connected to.
There is some example code on the Arduino website:
http://playground.arduino.cc/Interfacing/CPPWindows
It's then up to you to decide on a protocol for passing data back and forth. This depends entirely on your needs, so we can't really help you unless you give more information.
Is there a library/method for communicating with a microcontroller (Arduino)?
Basically, I need a method of receiving and sending data between the PC and the Arduino. I don't know what library to use, so I'm asking you. The data I'm going to send is little. Maybe 500 bytes back and forth. Everything is happening in Visual C++ 2010, in a console application.
libusb seems to be one of the best choices in your case. This is a lightweight, widely-used, open-source, cross-platform and well-documented C library.
termios also works fine. I've been using it to connect an Arduino to a Raspberry Pi (Linux) via serial link (USB). You could find some useful code snippets here.
Boost ASIO works well. Have a look at Stack Overflow question Reading messages from a serial port with Boost Asio. I recently had to write some code for communicating through the serial port, and I used an Arduino Uno to test it.
If you install the FTDI driver for your Arduino board, Windows will recognise it as a COM port, and you can communicate with it as if it is a normal serial port.
Yes, ArduSerail is a SUPER easy to use C++ library to interface with Arduinos on Windows platforms via USB.
i am electronics and communication engineering student. i am working on a project in which a microcontroller send data to serial port of computer (asynchronously).
i currently learning wxWidgets for my GUI work.
my question-
is it possible to do using wxWidgets to get data and display. is it very difficult to implement this.
i search for it but not get direct answer that how to implement this. so suggest me what i need to read for this. and what alternative available to do this. i use windows 7.
i also need to upload this data to web server (it is needed later)
wxWidgets, to the best of my knowledge, does not implement serial I/O facilities. There are other libraries available that provide this. One of the best choices is probably boost::asio (see http://www.boost.org/doc/libs/1_40_0/doc/html/boost_asio/overview/serial_ports.html)
wxWidgets is a cross-platform GUI framework.
Reading a serial port is nothing to do with the GUI, and not cross platform.
So wxWidgets has nothing to do with reading serial ports.
You can read/write from/to a serial port using the windows API.
CreateFile opens the port
ReadFile reads data from the port
Difficult? Kinda!
I've never used it myself but there is wxCTB.
