Is there a way to avoid double buffering for i2s

[Divya BM]

Hi,

We are aware that i2s internally includes hardware double buffering to ensure that the audio is continuous.

Is there any way by which we can avoid double buffering or provide new data to i2s as soon as possible instead of waiting for the TX interrupt?

Hello, Divya!

I'm asking the developers whether this is possible or not. Thank you for your patience.

Hi Carl,

Any update on this?

I have not heard back from the developer yet, but a fellow engineer purposed that you piggyback the TXTRUPD event, and initiate next TX at once when it arrives. The speed of this will of course be limited by the 1 word minimum size of the RXTXD.MAXCNT, but it will leave you in control at least.
