Hi,

I wan to Stream the Wave file Audio from ALSA(aplay) over McASP0 lines.Can you please suggest me how shall I start ? I am using Beaglebone Rev3.

I am interfacing the Beaglebone MCASP lines to NUVOTON Sound card chip I2S lines.Here I need to use I2S data lines only.

NUVOTON chip programmig is done by other Microcontroller chip control interface(Not Beaglebone).

I want to stream the Audio data over these lines.NUVOTON is the master and supplies FS clock(8KHz) and Bit clock(256KHz) always.

Info :

MCASP0 lines : LCD_DATA8.mcasp0_aclkx,LCD_DATA9.mcasp0_fsx,LCD_DATA12.mcasp0_axr2,LCD_DATA12.mcasp0_axr3

 

Thanks.

Ibrahim
