Hello, everyone,
I am checking the I2S example (cyfxusbi2sdmamode in SDK 1.1.1). I changed nothing in the firmware. Now I found that BCLK(2.82MHz), MCLK(11.28MHz) and LRCK(44.1KHz) are correct. I tried to send data (not 0 ) in the control center and it shows transfer is successful. But the SD pin are always 0. Did anyone have the experience of I2S?
Thank you very much,
Lehua Chen

It works now. After I wrote 1024 bytes in the Bytes to Transfer (FF) in the control center, I chose alternatively endpoint 0x01 and endpoint 0x02 to transfer data. Then I got reasonable pulses at the SD pin.
Best regards,
