I am using audio core to generate digital audio filters . I want to pass digital signal from ADC to DAC , but it can't operate . Who can help me this problem . Thank you very much !!!

here is my code by C 

while(1) {  //wait for interrupt signal  ctrl_reg = IORD_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE);  ctrl_reg &= ALT_UP_AUDIO_CONTROL_RI_MSK;  if(ctrl_reg == 0) continue; //if there isn't read interrupt signal , continue wait  ctrl_reg = IORD_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE);  //clear interrupt flag  ctrl_reg &= ~ALT_UP_AUDIO_CONTROL_RI_MSK;  IOWR_ALT_UP_AUDIO_CONTROL(ALT_UP_AUDIO_BASE, ctrl_reg);  //read left channel  alt_up_audio_read_left_channel(&left_reg,read_length);  //read right channel  alt_up_audio_read_right_channel(&right_reg,read_length);  // write left channel   alt_up_audio_write_left_channel(&left_reg,write_length);  // write right channel  alt_up_audio_write_right_channel(&right_reg,write_length); }

Try this example, let me know if it works. 

# include "alt_up_audio.h"  // assumes input only from right channel int main() {  unsigned sample_count;  long audiobuf[128];   alt_up_audio_reset_audio_core(); //get the audio started  while (1)  {  sample_count = alt_up_audio_read_right_channel(audiobuf,128);  if(sample_count)  { //must write both output channels  alt_up_audio_write_left_channel(audiobuf,sample_count);  alt_up_audio_write_right_channel(audiobuf,sample_count);  }  } }
