Using Virtual Serial Ports in Proteus

Proteus is an extensively used software favored by developers and engineers to simulate electrical circuits. Proteus is regularly used while modeling and designing programmable gadgets consisting of microprocessors and microcontrollers.
We present this brief tutorial showing how you could create digital serial interfaces in Proteus using Eltima’s Virtual Serial Port Driver software.

Our demonstration will contain checking out a microcontroller software’s functionality. A "host application" can be used to ship facts to a microcontroller thru the UART communique protocol. We have chosen to enact this verbal exchange with a MAX232 chip, that's a UART-COM converter, to connect the microcontroller to the pc.

Method of working with Proteus

Proteus is our device of choice to confirm the communique among the microcontroller and laptop. We will add a serial port model that connects the RDX and TXD, making sure that any facts transmitted to the microcontroller are despatched right returned to the laptop. This will affirm that Proteus is capable of establishing a serial verbal exchange.
It would be excellent if there has been a native facility inside Proteus that creates digital serial ports with which we may want to simulate conversation with bodily ports. In that case, we could simply use Serial Port Terminal to serve as the host application and run a tool simulation on Proteus to evaluate the relationship. We will, but, need to rent additional software program if we prefer to create virtual serial ports in Proteus.
Proteus interacts with the COM port model using a useful resource called COMPIM.

What is COMPIM in Proteus?

COMPIM is used to model bodily COM interfaces in Proteus. It works using capturing and buffering serial indicators which it then provides to the electrical circuit. The pics serial ports could be used to behavior all serial information originating from the CPU or the UART model.
Virtual serial ports can also be created the usage of USB or Bluetooth connectivity with the aid of using numerous technical workarounds. Baud rate conversion is possible whilst the usage of the COMPIM model. Verification of the virtual and physical characteristics of the tool can be implemented through the addition of non-obligatory hardware to software.
Two ways of running with Proteus

Testing the "host program" "COM port" "device version functionality in Proteus can be accomplished with both of these two techniques.
Use two computers linked via their serial ports. One machine is used to run the host program even as the other computer runs the device simulation.

Using a serial cable to connect to bodily ports, one in every of that is where the host software is walking even as the second is configured as a virtual port in Proteus.
