Hi all,

I have a DE2 board and I´m developing a project that use de Expansion Header GPIO_1 to connect two boards, so I have the follow situation :

When I configure the board_2 to be a receiver and the board_1 to be a sender, all is in correctly execution (the board_1 set the GPIO_1 and the board_2 light the LEDR according the values of the pins).

My problem is: when I configure the both boards like sender/receiver, the datas are not transfered through the GPIO_1 pins, even that the write happens in a different moments.

Can you help me??? Do you know if a have to use a bus management???

Any idea??

:confused:
