I use ADAU1761 with a BF707 development board. I use the codec only like dac and work perfectly. I send my data and the dac play audio stream.
Now I would like to use a feature of ADAU1761 DSP like filter.
For first I would like load a simple schematic in ADAU1761, the schematic must take the I2S stream and reproduce it with the dac.
I changed this setting:
- Serial Input rout control:
- Changed "Serial In L0-R0 to dacs" in "Serial input to DSP to dacs"
- Serial output rout control
- Changed "ADC to Serial Out L0-R0" in "Serial output to DSP to dacs"
With the default setting ( Serial in L'-R0 to dacs) the dac works, when I change in Serial input to DSP to dacs the codec not works.
I don't understand why my schematic not work. Could you find my project as attachment.
Thank you very much and excuse my english.
