timer problem

thanks for answer, i've started to use macroses, but timer still isn't working.

# include "system.h"

# include "altera_avalon_timer_regs.h"

# include "altera_avalon_pio_regs.h"

int main(void)

{

//turning timer on

// 1/(50 MHz) x (0x1DCD6500) = 10 sec

IOWR_ALTERA_AVALON_TIMER_PERIODL (INTERVAL_TIMER_BASE + 0x8, 0x6500);

IOWR_ALTERA_AVALON_TIMER_PERIODH (INTERVAL_TIMER_BASE + 0xC,0x1dcd);

IOWR_ALTERA_AVALON_TIMER_CONTROL (INTERVAL_TIMER_BASE + 0x4, 0x4);

run=IORD_ALTERA_AVALON_TIMER_STATUS(INTERVAL_TIMER_BASE);

run=(run & 0x00000002);

IOWR_ALTERA_AVALON_PIO_DATA(RED_LEDS_BASE, 0);

/////////////////////////////////////////////

while (run) //

{

IOWR_ALTERA_AVALON_PIO_DATA(RED_LEDS_BASE, 0x2AA);

}

while(1)

{

IOWR_ALTERA_AVALON_PIO_DATA(RED_LEDS_BASE, 0);

}

}
