Not sure is AS sets it automatically when you put data in the register or if you also have to set that yourself.Now in simulation you have a source of fake input each time you call UARTgetchar().
Virtual Serial Port Simulation Proteus Simulator In AS4That was an add on that hacked into the simulator in AS4 that provided things like terminal simluation. I think (2) will tell you if it thinks you have got the speed thing wrong but Id kind of hope for that accuracy when paying 300. You might as well get some debuggable hardware and try this for real. But the OP should be able to test the posibility very easily and quickly. Now connect your hardware with the computer and play the simulation. Virtual Serial Port Simulation Proteus How To Use ALets come to todays topic, as the name suggests, today I will show you how to use a virtual terminal. In todays tutorial, we will have a look at How to use Virtual Terminal in Proteus ISIS. Virtual Serial Port Simulation Proteus Serial Modules II will first explain what is virtual terminal and then we will have a look at its uses and performance in Proteus ISIS.Virtual Terminal is an important tool available in Proteus and it comes quite in handy while working on serial modules i.e. GSM, GPS, XBee etc. So, lets get started with Virtual Terminal in Proteus. In windows XP, theres a built in tool named Hyper Terminal, which is also used for the same purpose but in windows 7 theres no such tool, so for windows 7 users this virtual terminal is quite a great comfort. If you guys dont know about serial port then I would suggest you to read this tutorial to get better idea of serial port: What is Serial Port. I have posted many tutorials on my blog in which I have communicated over Serial port using different software. For example, you can check this Serial communication in MATLAB and can also have a look at Serial Communication in Visual Studio 2010. As serial communication is too common, so almost every microcontroller supports Serial communication. Arduino UNO has builtin single serial port at its pins 0 and 1, while Arduino Mega 2560 has built in four Serial ports in it. Similarly, PIC Microcontroller also supports Serial port and it is also available in 8051 Microcontroller. Virtual Terminal in Proteus, as I explained above, is used to send or receive data to or from a serial port. Serial port is a 9 pin port which is mostly find on the computers and is used in Embedded System Projects for data communication. Normally in student projects, data is sent from hardware to computer via serial port and then user design some application on their computer to view that data in some represent-able form.Now, in projects there are some testing steps which are quite helpful, if we use them properly, and these testing steps require some tools in order to test the process. Like, suppose some student have designed the hardware to send the data to the computer and have also design its application to receive it and now when he tests it he didnt receive any data. At that point student got tensed and dont know wheres the error so at that point theres may be some error in the hardware or may be in the software.Now, in order to be sure he need to test both of them separately and here is the point where virtual terminal is used. ![]() If you are receiving it, means your hardware is okay and the problem is in software side and if you are not means your hardware is not so good.Whenever I start working on some projects, I always make sure that I am going in right direction like if I have to made this project then after completing my hardware, I will first check it via this virtual terminal and once I got sure that my hardware is okay then I will move to the software part. If you are gonna design the hardware then I think you must check Serial communication with 8051 Microcontroller, which is also designed in Proteus ISIS software and the data is displayed using the same virtual terminal.There are also many other applications of this terminal like suppose you wanna design some circuit in Proteus which involves serial port then you can add this terminal on your circuit and can test it before going to the hardware, which we will shortly see below. How to Use Virtual Terminal in Proteus ISIS First of all open the Proteus ISIS and click on the P button to search for the components, as we seen in previous tutorials. Now in the search box type COMPIM, when you search this a result will show up as shown in the below figure. COMPIM is the serial port in Proteus and using its properties we can assign any COM pin of our computer to it and it will behave like that pin. Now, click on the Virtual Instrument Mode and then on the Virtual Terminal as shown in the below figure and add it in the Proteus workspace. Now join the TXD pin of COMPIM with the TXD pin of Virtual Terminal and RXD with RXD as shown in the figure below: Now, double click on the COMPIM to open the Properties menu and set the properties as shown below: I have selected COM1 and my baud rate is 9600, you can set it whatever you want like if you are using the COM3 then set the port to COM3 and baud rate of your own choice. Similarly open the properties of the virtual terminal and make sure that the baud rate is same in both the cases.
