Other Parts Discussed in Thread: TLV320AIC3256, TIDA-01236, TLV320AIC3268
Dear sir,
I am a new user for audio codec TLV320DAC3203 using, we are using TLV320DAC3203 (by pin 6 for data and pin 9 for clock) to collect ultrasonic signal (20K~80KHz) from PDM microphone SPH0641LU4H-1 and use TLV320DAC3203 by I2S interface to connect to Micro-controller, how can I transfer the PDM data signal to PCM data signal to micro-controller by using the Decimation filters in TLV320DAC3203? The ultrasonic signal frequency from SPH0641LU4H-1 can be 20K~80K. Which filter I should use for and could you show some example code to me and see how to fix this issue? Thanks.
Best Regards!
Tyler
