Member Data Documentation

dst

uint8_t* no_os_dma_xfer_desc::dst

Destination address for the data

extra

void* no_os_dma_xfer_desc::extra

User or platform defined data

irq_priority

uint32_t no_os_dma_xfer_desc::irq_priority

Transfer complete interrupt priority level

length

uint32_t no_os_dma_xfer_desc::length

Transfer length in bytes

periph

enum no_os_irq_peripheral no_os_dma_xfer_desc::periph

Peripheral which originated the transfer. Will be used to add the callback to the proper event list.

src

uint8_t* no_os_dma_xfer_desc::src

Source address for the data

xfer_complete_cb

void(* no_os_dma_xfer_desc::xfer_complete_cb) (struct no_os_dma_xfer_desc *, struct no_os_dma_xfer_desc *, void *)

This function will be called once the transfer completes.

xfer_complete_ctx

void* no_os_dma_xfer_desc::xfer_complete_ctx

Parameter for the transfer complete callback. This data should be valid at least until the callback is invoked.

xfer_type

enum no_os_dma_xfer_type no_os_dma_xfer_desc::xfer_type

Transfer direction
