Other Parts Discussed in Thread: CC3200, TLV320AIC3106
hi, i am working on tlv320aic3106 audio codec interface with cc3200 i successfully configure the audio codec registers using I2C then i try to read I2S data from audio codec but the I2S handler cannot read any data
I can see signals on I2S bitclock, I2S word clock and I2S data line using an oscilloscope. i am using CPU mode with out RTOS Please check below circuit and configurations.
Pinmux configuration
