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!

Hello,
I couldnt quite understand some of your post. What inputs and outputs are you using?
Kind regards,
ED
Inputs is microphone,and outputs is horn.The process is MIC->ADC ->I2SADC ->I2SDAC -> SPK.
Best regards!
Hello,
I have attached some example scripts for your path.

Dear ED_Dialog ,
I have find the problem,Two capacitors in HPCFP and HPCSP is in the wrong position.Thanks very much!
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,
ED
