안녕하세요.

MV2440으로 MIC 시험중에 문의드립니다.

DNW에서 \'2440Test-r04d.bin\' 테스트 프로그램으로

아래와 같이 시험중입니다...

2:Record Sound via Line-In and Play it.

==========================================================

Press Enter key to exit : 1

Record Sound via MIC-In.

Select IIS Master Clock Source
0:PCLK, 1:MPLLin
1

IIS Master CLK(MPLLin) = 16.93 MHz
IIS Codec CLK = 16.93 MHz
IISLRCK = 44100 Hz

Are you ready to record sound via MIC-In on SMDK2440?
Press any key to start record!
Recording...
............................................................
End of Record!


IISLRCK = 44100 Hz
If you want to mute or no mute, Push the \'EIN0\' button repeatedly.
Press any key to exit!

Play...

====================================================================

스코프로 CODEC CHIP(U10, UDA1341TS)의 2,4번 핀을 찍어보면

신호가 들어가는것을 확인할 수 있는데,

PLAY가 될때에는 아무런 소리가 안나고 있습니다.

MIC시험은 어떤방법으로 해야하고,

어떻게 확인할 수 있는지 알려주시기 바랍니다.

답변 부탁드립니다.

그럼 수고하세요.
