Configurable O/p's on DE-II

Hi All,

I am pretty new to this forum and FPGA.

I purchased a DE-II board from altera.

I want the expansion headers to control some of my other circuitry which are at 2v5.

But the problem is that i get only 3v3 at the output of the expansion headers.

As far as i know the O/p levels of the FPGA or the cyclone - II are configurable.

Please let me know how can get 2v5 at the expansion headers.

With Regards

Bobby
