hi everyone!

I am a university student and i am doing a project about implementing a simple calculator by FPGA.

Actually, I construct the circuit of my calculator by Matlab System generator, with the help of EDK processor tool, I export the design to the XPS as a project.

I can display the result after computation on the hyper terminal window by setting the two input numbers in the C-program.

Now, i want to modify my project that the two input numbers are input by the user through typing the number by PC keyboard and display on the hyper terminal, then my circuit will help me to compute the result.

Can anyone teach me how can I do this?

I am now using : Spartan 6 board, with one UART port and one program usb connect to PC.

Thanks!
 

you need a level translator max232 IC... check if you have this IC on the board... connect the serial cable to your kit and PC and set the parameters on the terminal as 9600 baud rate, 8 data bit, 1 stop bit and no parity and hardware control as none..wrtie a small program to receive data from serial port and store it in 2 variables and do the required operation..........
