CCS/AM5728: steps to copy the contents of audio received in rx buffer to a storage location using API libraries

Part Number: AM5728

Tool/software: Code Composer Studio

Hai,

i am using AM5728 GP EVM. i am using the MCASP_Audio_evmAM572x_armExampleProject provided in ti-SDK (ti-processor-sdk-rtos-am57xx-evm-05.01.00.11-Linux-x86-Install.bin). Is it possible to copy the contents of rxbuffer(McASP Buffer) to sdcard or any storage on the board. if so i wanted to know the process of how to do it in the code. My issue is to copy the audio received through mic to a storage place (SD card).

is there any startup example project for my issue otherthan McASP example project.

Thanks & Regards,

Venkatesh R.

Hi,

You can refer to the below FATFS and MMCSD driver examples to write audio data into MMCSD card:

Rav,

You can also refer to the Audio Pre-processing Demo demo as an example. This example for AM572x is a file based demo that reads and stores processed PCM data that is similar to RX buffer that you may have from MCASP.
downloads.ti.com/.../Examples_and_Demonstrations.html

Note based on what data format you picked in the MCASP driver configuration the Left and right channel data may be interleaved or not. I believe the file based audio pre-processing demo processes 10 seconds of a 16 KHz sampled audio from 7 mics and stores the processed PCM data file.

Regards,
Rahul
