I am working on SDK2.0 USB stack forK22 series micro-controllers.

My aim is to read .mp3 files from mass storage device and play it on speakers, so want the information.


I know that audio files are sent over Isochronous transfer type and i am using USB_HostAudioStreamSend() function send audio data. So the question is do i have to create timer of 125us and call USB_HostAudioStreamSend() function again to send complete data or callback function is called after 125us?


if i am missing something please let me know. Just want to know how implement in my code.
