Using expansion header

I have a DE2 board and I want to use the 5-Volt power pin in the expansion header to power one of my peripherals. Do I have to set the voltage of this pin explicitly in software or does it always supply voltage when the board is powered on??

You don't need to set anything. Actually, there isn't anything to set. The power pins are just that: pins connected to the power net.

Hi.. 

The DE2 Board provides two 40-pin expansion headers. Each header connects directly to 36 pins on the Cyclone II FPGA, and also provides DC +5V (VCC5), DC +3.3V (VCC33), and two GND pins.I am using this..It works good..

Hello friend, I need urgently to understand how use the expansion header (GPIO) to obtain data from a sensor that I'm trying to integrate the DE2 board. A sensor wire is connected to GND and the other to pin 0 of JP1. How do I get the pin as concerned with the C language using the NIOS II? Please help me! A hug. I await answers.
