Reading external data using On-chip FIFO and NIOS II

Hi all, I'm trying to read a 8-bit ADC with parallel output using NIOS II. I need to read the ADC at 24MHz to capture correct samples. I have been trying a 1K On-Chip FIFO to capture this data....

I tried 


while(1)
{
    alt_u32 level = altera_avalon_fifo_read_level(0x2001800);
    printf("LEVEL = %d\n", level);
}

and received "LEVEL = 0" in the polling.
