Hello,

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?

Best regards!

I found the SPEC of MIC2

I found the SPEC of MIC2_Select is wrong,so the DA7218_configure.exe is.

Hello,

Thank you for the update.

I didnt quite understand when you said there was an error in the spec. What did you spot?

Kind regards,
