ask for EV-21569-EZKIT sample-based audio passthrough example in CCES

Category: Software
Product Number: EV-21569-EZKIT
Software Version: CCES2.11.0

Hello!

In EV-21569-EZKIT examples, Audio Loopback TDM and Audio Passthrough I2S are both block-based example. Could you please give me an CCES example of sample-based audio passthrough in EV-21569-EZKIT.

  • Hi Ruizhang,

    In 21569 EZKIT, ADC supports sampling rate range from 8kHz to 192kHz. We can set this sample rate ranges by setting 0 to 2 bit of the ADC SAI_CTRL0 register. For more information refer the Table 20. Bit Descriptions for SAI_CTRL0 in ADAU1979 datasheet. But, DAC only supports the sample rate range from 32kHz to 192kHz. We can't set the sample rate below the 32kHz in DAC register. For more information refer the Table 31. Bit Descriptions for DAC_CTRL0 in ADAU1962A datasheet.

    Please refer the ADAU1979(ADC) and ADAU1962A(DAC) datasheets in the below link:
