We meet a issue at ADAU1761 digital mic application.
I have build a project recieve digital mic signal successful, but I found the DSP have recieved two channel signal while I just connect single PDM mic, and the signal seems copy from anohter which show in Level detector block.
is the PDM signal channel not depend on LRSEL(PDM MIC)? how to set it avoid single signal copy to another?
attachment is a dsp project, which also come from EZ.
Just need single MIC signal into 1761,any response?
