Configuring McBSP of OMAP3530

Other Parts Discussed in Thread: OMAP3530, TPS65950, TPS65930

Hi All,

I am trying to configure the McBSP2 of OMAP3530 .

My Assumption: Speakers are connected to TPS65950. Audio is rendered with the help of McBSP2(got an audio buffer). McBSP2 communicates  with the TPS65950 module  which in turn  renders the audio through speakers. Please correct me if i am wrong here.

My intention is to render an audio file .

In the use case given in the 21.6.1.1  it shows how to configure McBSP to receive voice streams from TPS65950 device. 

 

Is that alone enough? I think TPS65950 should also be configured right? Please help me on this?

 

Regards

Jack

    That is the basic process, though there are other software layers on the OMAP as well as configuration of the TPS65950 over I2C that come into play, but the audio itself is moved over the McBSP2 interface to the audio codec within the TPS65950.

    You are correct that the TPS65950 should also be configured/controlled, which is done through the I2C interface. Assuming you are using Linux, there are already audio drivers in place you can use, for further information on the Linux audio driver included with the PSP driver package see chapter 5 of OMAP35x_SDK_1.0.2\docs\OMAP35x\UserGuide_1_0_2.pdf, note that even if you are not using Linux in your application that the source for this driver may be useful. There is also some simple audio test code in OMAP35x_SDK_1.0.2\board_utilities\EVM3530_ITBOK that may be useful as well.
