We are using STM32F103R8T6 with DA7218.
STM32F103R8T6 output 8MHz to DA7212 MCLK.Sample rate for ADC and DAC is 48kHz .
1)MIC1_P and MIC1_P has signal output.
2)WCLK frequency is 48kHz.
3)BCLK frequency is 1.5MHz.
4)DATOUT output is changed when speak near to mic.
But when I jumper connect DATOUT ande DATIN,there is no sound.I'm sure I have enabled MIXOUT_AM and HP_AMP.I have attempt many times,Can anyone help me?
