Other Parts Discussed in Thread: TLV320AIC3254,
i'm using the TLV320AIC3254 as a codec between analog mic and speaker and a radio module.
Frames on the I2S interface ( Dout / WCLK / BCLK) so the TLV outputs are from 0 to 3.3V.
Signal from my radio module to the TLV ( module DOUT) are 0-3.3V when not connected to TLV DIN, but drop to 0-500mV when connected, so i've got no audio coming out on the analog side of the TLV.
The TLV is configured as a Master, 16kHz of sampling rate.
I'm using the TLV320AIC3254EVM-K to test the configuration.
I've checked the following :
- Page0 / Register 32, D0 is set to 0 (DIN is used for Audio Data In).
- Page0/Register 54 igot D2-D1 set to 01 (DIN is enabled for Primary Data Input or Digital Microphone Input or General Purpose Clock input)
Can someone assist to understand why the received signal is lowered?
