Hi! i am new to dsp programming and trying to use audio example code packaged with code composer studio on dsk6711. but it seems like input jack for mic is not working.... there is no valid incoming signal from the codec...... plz can anyone point out a way through which i can verify whether my mic input jack on dsk6711 is working or not? or if someone has some knowledge about this sort of problem.. may be caused by some logical fault in code...? |

The problem which I know is it needs Pre-Amp in front of the Connecter. You might use the pre-amp box (Mr. Rulph Chassaing told me)or the "dynamic microphone " to amplify the voice. But I am not sure it is feasible or not about codec programming in CCS. In my way , I plugged the mic to PC ,then connent the output from the PC (All with Audio Card)to J7 .I found it could work. The speaker connected with J6 could heard my voice. So please try again! The loop is "Mic -->PC-->J7-->DSP-->J6-->Speaker".Good Lucky! Ke-Han Su |

RE: [c6x] audio example for dsk6711
There is no microphone pre-amp circuit ... so you need to use a powered microphone. Most standard PC type microphones do not come powered. Radio Shack has a powered version that requires two AA batteries. Regards,
