I need to have a library to read and write to the serial port to the arduino over C++ in windows. I want to write strings to the arduino, read chars from the arduino, check if the connection is working and if possible see if there is anything available from the arduino (and of course setting up a connection with baudrate, port etc.).
I have looked at the "Arduino and C++ (for Windows)" topic in the playground, it looks good, but how to I use the ReadData and WriteData and how do I set the Baudrate?
I have an Uno.
P.S. It can be in Qt.
