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

The output voltage level is fixed in the board hardware by connecting bank VCCIOs to respective supply voltage levels and can't be changed through software settings.
