Hi @MN19000 ，

  Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

  The Ring buffer size is determined by your requirement, so, the max size is determined by your definition.

In the SDK, size_t ringBufferSize

typedef unsigned int size_t;

I think the unsigned init size is enough to you.

Wish it helps  you!

If you still have question about it, please kindly let me know.

Best Regards,
