Using a text file to control DE2-70's Led

Hello all

I have a small project about control DE2-70 board . My mission is send a text file (.txt) to DE2-70 by JTAG interface from my computer . The file store an 8-bits binary , the board must read the file and show the value of 8-bits on Leds. But i can't figure out how to send a text file and store it in sram so the board can read it . Please give me an advice or show me a link that tell about my problem.

Sincerely

Thanks

    Hi darkness,

    You may refer to a design example in the DE2-70. In the section 3.2, you

    are able to find an example which user is able to type characters to the LCD

    from a terminal through an USB port.

    Dear Peter.chang

    I appreciate your advice . I have already tried this examle before post this question , it's using de2-70 control panel to control the board . In my project , i have to build a small software that allow you to choose a .txt file and send it to de2-70. In your opinion , it's easy ? normal ? hard ? or very hard ? . I don't think we have any software allow us to do that .

    Sincerely

    Thanks
