HELP me in RS232

How?? there is the data...how to send to out from one board to another board or how u do..any module?rs232 module?

Hi cycy, i found this link that could help you but it is for the DE2 board.

http://www.johnloomis.org/digitallab/rs232/rs232lab.html

I have tested it with my DE2 board. After you have download the code into your board you can also use this to connect your board to your pc .(In my case i use usb to serial converter). The program i use to transmit the data from pc are free program called Realterm.

http://realterm.sourceforge.net/

This program can submit data to the board and also displays what the board has sent to your pc.
