Tool/software: TI C/C++ Compiler
Hi,
I have been using the PADK - Professional Audio Development Kit, to achieve active noise control for some time now. It is a multiple channel I/O incorporating the TMS 320C 6727 DSP.
However, Im just getting some problems with the ADC input channels. Normally, i connect the output of an electret microphone directly to one of the ADC input channels and the input signals are processed by the DSP. But now as i connect the output of the microphone to the ADC channel (anyone of them is the same), the voltage at the microphone output (sane as that of the ADC input channel) freezes and the mic no longer works. I have been doing a lot of tests to find out where the issue is. and I think that the problem lies with the ADC input channel. But I am unable to trouble shoot it and if necessary to reset the ADC input channels.
Is anyone aware of that issue? and any solution to that.
Thanks,
regards,
Sajaad
