UWP and Android versions are on their way. SerialPort.Net is a good starting point for connecting and reading from the COM ports. The Windows sample should list devices connected to COM ports like so. SerialPort.Net is not yet fully documented, but documentation is on its way. Using SerialPort.NetĬheck out the documentation for Device.Net here. The app sends a buffer of data to the device and then waits to receive a buffer of data with ReadFile. However, many devices require a request/response pattern like Http calls. It can be called in a loop so that whenever data arrives on the port, the app can consume the data for the principal purpose.Ĭall WriteFile to write a buffer of data to the device. SetCommTimeouts should be called to specify the maximum time a call should take.Ĭall ReadFile to get data from the device. If the documentation doesn’t specify this, it might be necessary to contact the manufacturer. If you don’t know these, you should look at the documentation for the device. It includes things like Baud rate, parity, byte size and other settings which are specific to the device. If this is successful, the app must call SetCommState to specify the settings for serial port communication. It ensures that the end of the using block closes the handle automatically. Device.Net uses SafeFileHandle because it implements IDisposable. CreateFile creates a filehandle that can be used to access the device’s data. The first parameter is the id of the COM port and looks like the text below. The method for doing this is this CreateFile Windows API. Once the app detects a device COM port, streams must be opened to read or write from the device. If there is no registry access, it is necessary to iterate through the ports and try to connect on each one. Each key contains the name of the COM port, which includes a number. If you have access to the registry from your app, you can check which devices are connected by calling this code. The app can find COM port devices on Windows in HARDWARE\DEVICEMAP\SERIALCOMM of the registry. GPS units and weigh scales send a constant stream of data to your computer, which the app can then interpret as latitude and longitude or weight. Some typical examples of serial port devices are GPS units and weigh scales. On Windows, this generally means iterating through COM ports until data can be received. Like any other communication with connected devices, the first step is to scan for a connected device. It is a library for communication via the serial port which is usually a COM port. So far, it has covered USB and Hid communication, but recently SerialPort.Net was added to the framework. The Device.Net framework is a framework dedicated to making it easy to communicate with connected devices. Join the conversation on the Device.Net Discord Server This article relates to the Device.Net framework. NET, but subsequent articles look at UWP and Android. This post discusses the basics of reading to and from serial ports with C#. Some USB devices communicate with your computer via the Serial Port. In some ways, serial port access is more straightforward than Hid, or USB access, but there are some tricks to it. One of the oldest ways is via the Serial Port. There are various ways connected devices communicate with your computer.
