audio core

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);

}

}

}

Hello, i am having the same problem , so is there any workaround for this?

Thanks!
