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
