when we use cyw20706 to receive the i2s smart voice, how to connect the hardware, there are some noise in I2S clk/dio,show as below; do you have any advice?
It seems you missed the waveform. The I2S/PCM interface for CYW20706 is fixed.
If the CYW20706 act as a I2S slave, the clk is supplied by the master device. You may check the master side for the reason.
