![]() But, it may not happen because of CPU scheduling issues, etc. At this time, normally, windows ques your work instruction and sends them to devices. After writing, and before you start reading the response, it’s always good to wait for a while, thus adding a slight delay, which helps to make up the time required between receiving and sending a reply for the device. This array can contain several hex values to represent a single command. Then, we will write an array of bytes to the port. The first thing we are doing here is discarding existing buffers if any. do other necessary processing you may want. While ((SerialObj.BytesToRead = 0) & amp & amp (tmrComm.timedout = false)) ![]() TmrComm.Interval = timeoutperiod //time to time out in milliseconds Public void OnTimedCommEvent(object source, ElapsedEventArgs e) TmrComm.Elapsed += new ElapsedEventHandler(OnTimedCommEvent) TmrComm.Interval = 1000 //default to 1 second The following C# code examples will return a list of Serial port names connected to the computer: As a prerequisite, you need to make sure that, while the application is running, the windows user must need to have access to the ports. OK, let’s first see whether we can detect the serial ports from within our application. If you want your laptop to live a long life you’re going to need to get rid of the heat inside of it, Laptop AXS can help you choose a good cooling pad for your laptop and avoid these issues. But if you are using any specific type of device which facilitates this kind of communication via USB interface, you can retrieve their PID/VID respectively and communicate accordingly.NET has a very useful internal class that can make this kind of communication to be very easy and efficient. One interesting thing that you might need to remember is that, when the physical serial port is being used, it doesn’t have any PID or VID. ![]() This type of communication isn’t as easy as other similar tasks such as working with a logic drive on a computer via c# and needs the use of a specific kind of communication protocol. If the device does require a serial port and your computer doesn’t have any, you can make use of such converters easily. Serial communications can be done either directly to a physical serial port connected to the computer or via a USB-to-serial converter interface. In today’s programming tutorial, I am going to describe some basics about how we can perform serial port communication from our C#.NET applications. ![]()
