TM4C1294NCPDT: USB audio transmit data upstream example

Douglas Todd

Part Number: TM4C1294NCPDT

I am looking for an example of how to transmit audio isochronous data from the Tiva TM4C1294 processor upstream to a host computer. I have a number of A/D converters that stream data, and I want to transfer the data.

Are there extensions to usbdaudio.c/usbdaudio.h that handle the transmission of isochronous data? Are there examples from other related processors.

Thank you very much.

Hello Douglas,

We don't have a ready to use example but a similar topic came up not long ago and that customer shared some of the code modifications/extensions they had done to get isochronous audio transfers working: https://e2e.ti.com/support/microcontrollers/other/f/908/p/803319/2975611#2975611

Have a look through that post and see if that is sufficient to get rolling on your end as well.

I am not sure about examples for other processors.
