Plz can you help me to tell me How to configure the ((Serial library for C++)) in visual studio C++ Express??? Thank you for helping Read sample code gets into a loop. Simple C++ class example using serial port, USB, wireless This post is part of the Practical C++ programming tutorial for Bioloid Here you can find a post serie about using serial port communications with C/C++ and C#, for Windows, Linux and microcontrollers.
I have a project in which i draw in drawing and same thing is drawn in glcd. Through serial communication, byte buffer2send = new byte1; byte data2send = 0; data2send = Byte.Parse(textBox2.Text);//this way you will get the value 12 in your variable //we will use a buffer because the serialport.Write takes either a string or a buffer of data buffer2send0 = data2send; MessageBox.Show(“” + buffer2send + ” ” + buffer2send.Length); serialPort1.Write(buffer2send, 0, buffer2send.Length); i basicaly send 12 or like this values on microcontroller but at recieving side i cant recieve respective value so plz guide me. If you have an application that writes to a serial port device through a USB adapter, and the application is hard-coded to use COM port 5, is there anything you can do so that moving a laptop that uses this application from one docking station to another will NOT cause Windows Plug and Play to assign a different COM port based on the VID of the second USB-to-serial device being different from the VID of the first USB-to- serial adapter? The docking stations both use the same peripherals, all plugged into the same USB ports. The users of these laptops don’t have administrative rights to change the COM port in Device Manager. Some USB-to-serial adapters advertise ‘COM port retention’, but that only seems to make the laptop use the same COM port for the exact same USB-to-serial adapter (the very same one, not just one that ‘seems’ the same but has a different VID) each time the laptop is connected to that device.
Usually the device manufacturer provides an API for interfacing the device with the PC (read the documentation). Very often (for low speed devices) they provide a serial port emulator, that is you communicate with the device using standard RS232 communication (again, check out your device documentation). As about Windows API: Windows is the Operative System, the API it provides are not only the ones used for 'the windows'. Specifically serial communication ( USB included) functions are ready-to-use for console applications. update If you are using the FTDI chip a chip then (assuming the corrensponding driver is installed on your PC) you use standard RS232 API for communicating with it (see for instance: ) on the PC side. On the other side you typically have a, hopefully, a microcontroller with UART device.
To access USB devices you must talk with the device specific USB driver using a library provided by the device manufacturer (or the manufacturer of the used USB interface chip). Whithout knowledge about the used device, nobody may help you here.
Console applications can call Windows API functions (and most existing console applications do so). How would you access a file or a serial port from a console application without using API functions? If you don't know much about interface programming and your device has a serial port, you may buy an USB-to-RS232 converter. Such converters provide a virtual serial port interface that can be accessed like a physical port. When answering a question please:. Read the question carefully.
