i2s How to get data .

Hi:

 How to get sine_table[] data,like this.

int16_t sine_table[]= {0,0,23170,23170,32767,32767,23170,0,0,-23170,-23170,-32768,-32768,-23170,-23170}; 

NRF_I2S->TXD.PTR=(uint32_t)&sine_table[0];
 NRF_I2S->RXTXD.MAXCNT=sizeof(sine_table)/sizeof(uint32_t);
 NRF_I2S->TASKS_START=1;  

I only have WAV files, such as tone.But I don't change it.

Hi,

If you need to to convert the .wav file to a sample .c source file / array, then the python script Convert Audio Sample\conv.py in this github repo can be used. Follow the instructions as specified within that folder to create the sample .c file.

hi,

Thanks for you help. I downloaded GitHub's file test. But I was missing some files. Like this.

Do you have pip installed? 

Then you could just do "pip install SoundFile" in the command line.
