Hi,

I'm following the second lesson of Teaching ROM of C5505, not 5535. And i use the micro phone which is provided togother ezDSP KIT to record my voice and an other headphone to listen, bit i still can't listen anything. I added the line to two functions like that. Can you give me an advice?

Thank you!

Hi,
Even I experienced the same problem with the microphone. But if I give the input from my ipod/mobile-phone. It works well. You can check my code in the link below:
