base | pointer to FLEXIO_CAMERA_Type. |
handle | Pointer to flexio_camera_edma_handle_t structure. |
callback | The callback function. |
userData | The parameter of the callback function. |
rxEdmaHandle | User requested DMA handle for RX DMA transfer. |
kStatus_Success | Successfully create the handle. |
kStatus_OutOfRange | The FlexIO camera eDMA type/handle table out of range. |

flexio_camera_edma_handle_t * | handle, | ||
flexio_camera_transfer_t * | xfer | ||
) |
This function receives data using eDMA. This is a non-blocking function, which returns right away. When all data is received, the receive callback function is called.
base | Pointer to the FLEXIO_CAMERA_Type. |
handle | Pointer to the flexio_camera_edma_handle_t structure. |
xfer | CAMERA eDMA transfer structure, see flexio_camera_transfer_t. |
kStatus_Success | if succeeded, others failed. |
kStatus_CAMERA_RxBusy | Previous transfer on going. |
void FLEXIO_CAMERA_TransferAbortReceiveEDMA | ( | FLEXIO_CAMERA_Type * | base, |
flexio_camera_edma_handle_t * | handle | ||
) |
This function aborts the receive data which used the eDMA.
base | Pointer to the FLEXIO_CAMERA_Type. |
handle | Pointer to the flexio_camera_edma_handle_t structure. |
status_t FLEXIO_CAMERA_TransferGetReceiveCountEDMA | ( | FLEXIO_CAMERA_Type * | base, |
flexio_camera_edma_handle_t * | handle, | ||
size_t * | count | ||
) |
This function gets the number of bytes still not received.
base | Pointer to the FLEXIO_CAMERA_Type. |
handle | Pointer to the flexio_camera_edma_handle_t structure. |
count | Number of bytes sent so far by the non-blocking transaction. |
kStatus_Success | Succeed get the transfer count. |
kStatus_InvalidArgument | The count parameter is invalid. |
