DE1 board to PC communication

Anyone knows how to communicate the de1 board to PC ?? for example: I need to send a data from my pc to de1 board, and make maybe a logic operation (or something), and after, receive the result data ...

Hi saadip,

I have no reason to believe that the method I used is in any way limited to a particular board design.

Jtag_atlantic.dll is in your Quartus installation folders ...\altera\quartus\bin

You will need the header file for your C++ compiler - I found one in this forum that works for me well under the name my_jtag_atlantic.h which contains the declaration of the public functions in the dll that you need. I attached the original file here.

If you are working in MS VC++ on your host - I can send you the test code that I used.

As for the FPGA side - its a bit tricky to figure out the actual mode of operation of the jtag_uart component. The documentation is not clear and I ended up using STP to figure things out. The FPGA system Qsys is attached for you. The StateMachine does all the housework for the UART and reads null terminated strings "test" in the screen shot, and responds in kind "OK"

I hope this helps.
