Hi,
If you try the DMA ringbuffer with the Teensy 3.1, it does not work as expected : only half the buffer is filled, I think that the correction needs to be done on line 85, you should have 2 \* b_s…

**Describe the bug**
Submitting large I2S DMA Rx transfer using I2S_RxTransferReceiveDMA(...) splits the transfer into multiple DMA transfers. This happens if I2S_GetTransferBytes() reduce the size. …

## Introduction
The I2C API's `i2c_transfer()` and async variants are currently loosely specified, leading to inconsistent and inefficient device driver behavior and usage. This RFC aims to update th…
