output GPIO on DE2

The board is just a plain old DE2 board. THey have since come out with the DE2 70 board.

I cannot get anything to output at all. I checked the Pin list and it's fine. I also checked the labeling. It is GPIO_0 or GPIO_1

Do I assign like this?

GPIO_1(1) <=clock_27;

or this

clock_27 => GPIO_1(1) ;

Thanks

Hello I m trying to use the output GPIO on the DE2 board and cannot even get the clock to output. I have pin one out of a breakout board running through a 1k and then to Comm.

My code was immensely simple

GPIO_1(1) <=clock_27;

Is there something wrong? Is there a spefic string of code I need to output anything?

What is the pin assignment? Perhaps you have a typo.

Is this a DE2, DE2-70, or DE2-115?

Here's a snippet from my DE2 pin assignments ...

set pin(gpio_a(0))              D25
set pin(gpio_a(1))              J22
set pin(gpio_a(2))              E26
set pin(gpio_a(3))              E25
...
set pin(gpio_b(0))              K25
set pin(gpio_b(1))              K26
set pin(gpio_b(2))              M22
set pin(gpio_b(3))              M23

and my DE2-70

set pin(gpio_a(0))              C30
set pin(gpio_a(1))              C29
set pin(gpio_a(2))              E28
set pin(gpio_a(3))              D29
...
set pin(gpio_b(0))              G27
set pin(gpio_b(1))              G28
set pin(gpio_b(2))              H27
set pin(gpio_b(3))              L24

Cheers,
