Fast Serial Communication For C# Real-Time Applications

While I’m working in AeroXtreme MAV Researching Project, i faced a serious problem in the serial communication in .NET C#. The standard C# serial component is too slow to handle fast serial communication for real-time applications. The MAV Main Computer send data over serial communication in high frequency and send a lot of data. When I used the standard C# serial library “Receiving Event” a huge lag of communication appeared and the buffers is jammed due to the high frequency of communication. After a lot of testing and debugging i found that the serial communication using the standard library will fail in such application so i tried to develop a Fast Serial Library to fulfill my requirement of real-time communication. My Library solve this problem and it can work with high frequency communication without any overhead on the processor due to the frequency control technique.

Virtual Serial Communication

The Universal Asynchronous Receiver/Transmitter (UART) controller is the key component of the serial communications subsystem of a computer. The UART takes bytes of data and transmits the individual bits in a sequential fashion. At the destination, a second UART re-assembles the bits into complete bytes. Serial transmission is commonly used with modems and for non-networked communication between computers, terminals and other devices. There are two primary forms of serial transmission: Synchronous and Asynchronous. Depending on the modes that are supported by the hardware, the name of the communication sub-system will usually include a A if it supports Asynchronous communications, and a S if it supports Synchronous communications. Some common acronyms are:

  • UART: Universal Asynchronous Receiver/Transmitter
  • USART: Universal Synchronous-Asynchronous Receiver/Transmitter

In This Post we will talk about Virtual Serial Communication and how to emulate serial port to use in you application or simulation.
