How to write data in a file from FPGA

 Hello, I am a beginner using Quartus and programming FPGA. I need to implement a binary search on FPGA and record the result of the search in a file (a 7 binary code each time). Below is the implem...

DE2-115 is a very nice development board, I also happen to have one of those.

It has a standard 9p RS232 compatible serial port, so you could just connect that to a PC via a COM port or a SERIAL/USB adapter.

So you could just implement a UART module in the FPGA and write text/data to the serial port and capture it on a PC.

It also has an SDcard socket, but that will require much more effort to use in any effective way.

Same for the etherNet port connections on the board.

    Thanks for the reply.

    So I only need to implement UART module in FPGA through Quartus and assign the pin of the module to Rs-232 and connect the R-232 to the PC?

      Correct.

      In fact you probably only need a UART transmitter module to send data from the FPGA to the PC.

      A UART transmitter is the conceptually simpler to implement compared to a UART receiver.

        I tried to implement a UART module in FPGA. The issue is capturing the data in the PC now I guess. How I can capture the data sent from the FPGA to PC?

        Thank you for your help.
