RTOS/TMDSLCDK6748: McASP configuration

Part Number: TMDSLCDK6748

Tool/software: TI-RTOS

Hello

I am a student of the Rotterdam University of Applied Sciences and we are doing a school project for Erasmus MC.

Erasmus MC wants Noise canceling in an incubator so we are going to develop that.

Now I am having the following problems

Change buffer length and where can if change settings like sampling rate in the MCASP_Audio_lcdkOMAPL138_c674xExampleProject

If I change the define BUFLEN to 1 because I want to process every sample real-time than the project doesn't work anymore.

Also I want to know where and how I can change the sample rate and other settings.

Another question is how I can change the Line in input to the MIC input because we do not use the Line in we use the MIC for the noise canceling.

I hope you can help me out with my problems/questions and hope to hear back from you soon.

Regards,

Roberto
