Play song AIC31

Matheus Vasconcelos

Hy.

I am using StarterWare in a BBB and I can run the audio examples, but my problem is, I want to read a file from SDCard an play via AIC31, some one have tried this and could send some help ?

I have a code that can read files from sd card and run the sample audio (toneRaw), but i do not know how to play from a file.

Thanks in advance.

Matheus,

I'm not understanding, are you trying to play directly from the SD card?

Hi Lalindra.
I want to save a file in the SD Card (i do not know the format), read the file and send via EDMA to the AIC31.
Thanks in advance.

Matheus,

You might have already seen this, but have you noticed the BBB DMA MMCSD examples in the Processor SDK package?

C:\ti\pdk_am335x_1_0_1\packages\MyExampleProjects\MMCSD_bbbAM335x_DMA_armTestproject

It might provide some help on what you are looking for.
