Audio Codec Talkthrough for EZ Kit Lite BF592

Hello,

I'm new with DSP, and I'm preparing for my bachelor thesis in which I would like to use the EZ Kit Lite BF592 Board. Concerning this board I've got several questions:

Does anyone have a "Audio Codec Talkthrough" -Projekt for EZ Kit Lite BF592?

Does anyone have a simple step by step Introduction to make use of the EZ Kit Lite Board/VisualDSP++?

Thanks you very much, I much appriciate your help,

cheers

  • Hi Guru,

    Following on from this, I'm now trying to get the mono 'MIC IN' input working (top 3.5mm jack input on J3). The ultimate objective for this part of the program is to be able to choose "line in" or "mic in" depending on user input.

    Currently, audio is received from the "line in" input (bottom 3.5mm jack input on J3), and audio is output from both 3.5mm jacks on J2.

    In the audio talk-through project example you gave above above, what needs to be changed to take input from the mono "MIC IN" 3.5mm jack input?

    I thought it may be a simple case of addressing iRxBuffer1[INTERNAL_ADC_L1] during EX_INTERRUPT_HANDLER(Sport0_RX_ISR), instead of iRxBuffer1[INTERNAL_ADC_L0], but this proved not to be the solution. There was no audio output whatsoever when I tried this. (Jumper JP5 is connected between pins 2 and 3)

    Thanks in advance,

    Carl
