HI snow

I suggest u can open the "altera_avalon_pio_regs.h" and "system.h" of NIOS2 project in the IDE and read it carefully.

use these followed macro:

IORD_ALTERA_AVALON_PIO_DATA(base)

IOWR_ALTERA_AVALON_PIO_DATA(base, data)

Reading the English Datasheet carefully before u program http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
