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 have a Wemos D1 Mini (ESP8266), flashed with WLED and I want to create an application like .exe and have control on turning it on/off and choose colors. Does anyone have any idea how I can do without to connect on wifi and just do everything via USB?
To control the WLED firmware over USB, you would use the firmware's ability to be controlled over a serial connection. It looks like you would open the virtual serial port that appears when you plug in the device, at a speed of 115200, and then you take the same JSON that you would POST to /json/state for controlling it over WiFi, and instead send it over the serial connection, and get your responses back over the serial connection.
You could also implement the TPM2 protocol, or the Adalight protocol (which doesn't really seem to be documented except in code), as those are also supposed to be supported.
If you want to do all this in C++ on Windows, you might start by reading the (very old) Windows tutorials for Win32 API serial port programming. If you only want to target Win10 or newer, you could learn C++/WinRT and then use the new WinRT serial APIs. Or you could consult the answers to this question about serial programming on Windows.
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 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.
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.
I know how to interface using the parallel port and also have a little idea on serial port interfacing. But is there a way to interface using the USB port in Windows? Or any links that would give tutorials on how to do this?
Specifically, I wanted to know the programming side of it.
I don't know how to start. I have searched into google but I have not seen any code samples.
Thanks in advance and Happy New Year.
USB programming is considerably more complex than serial or parallel port programming. For writing USB drivers for Windows, you'll probably need the Windows WDK. However, for a device you build yourself you can start with implementing a serial port class driver in your device, so that it shows up as a new serial port in Windows. The HID is another potentially useful driver class, generally used for some kind of input device.
I would recommend a good book if you want to do USB programming, for example Jan Axelson's USB Complete. And a real hardware protocol analyser is indispensable.
Found an interesting blog post http://yeohhs.blogspot.com/2006/08/programming-usb-port.html
it mentions a library 'libusb' and a wrapper for the same. The library is a GNU project. The library and documentation of the same may prove useful. The API documentation of libusb is here: http://libusb.sourceforge.net/api-1.0/
