541 This subsection provides a set of functions allowing to manage the UART asynchronous
542 and Half duplex data transfers.
543
544 (#) There are two mode of transfer:
545 (++) Blocking mode: The communication is performed in polling mode.
546 The HAL status of all data processing is returned by the same function
547 after finishing transfer.
548 (++) Non-Blocking mode: The communication is performed using Interrupts
549 or DMA, These API's return the HAL status.
550 The end of the data processing will be indicated through the
551 dedicated UART IRQ when using Interrupt mode or the DMA IRQ when
552 using DMA mode.
553 The hal_uart_tx_cplt_callback(), hal_uart_rx_cplt_callback() user callbacks
554 will be executed respectively at the end of the transmit or Receive process
555 The hal_uart_error_callback() user callback will be executed when a
556 communication error is detected
557
558 (#) Blocking mode API's are :
559 (++) hal_uart_transmit()
560 (++) hal_uart_receive()
561
562 (#) Non-Blocking mode API's with Interrupt are :
563 (++) hal_uart_transmit_it()
564 (++) hal_uart_receive_it()
565 (++) hal_uart_irq_handler()
566
567 (#) Non-Blocking mode API's with DMA are :
568 (++) hal_uart_transmit_dma()
569 (++) hal_uart_receive_dma()
570 (++) hal_uart_dma_pause()
571 (++) hal_uart_dma_resume()
572 (++) hal_uart_dma_stop()
573
574 (#) A set of Transfer Complete Callbacks are provided in Non_Blocking mode:
575 (++) hal_uart_tx_cplt_callback()
576 (++) hal_uart_rx_cplt_callback()
577 (++) hal_uart_error_callback()
578
579 (#) Non-Blocking mode transfers could be aborted using Abort API's :
580 (++) hal_uart_abort()
581 (++) hal_uart_abort_transmit()
582 (++) hal_uart_abort_receive()
583 (++) hal_uart_abort_it()
584 (++) hal_uart_abort_transmit_it()
585 (++) hal_uart_abort_receive_it()
586
587 (#) For Abort services based on interrupts (hal_uart_abort_xxx_it), a set
588 of Abort Complete Callbacks are provided:
589 (++) hal_uart_abort_cplt_callback()
590 (++) hal_uart_abort_tx_cplt_callback()
591 (++) hal_uart_abort_rx_cplt_callback()
592
593 (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
594 Errors are handled as follows :
595 (++) Error is considered as Recoverable and non blocking. Transfer could go till end, but error severity is
596 to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
597 Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
598 and hal_uart_error_callback() user callback is executed. Transfer is kept ongoing on UART side.
599 If user wants to abort it, Abort services should be called by user.
600 (++) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
601 This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
602 Error code is set to allow user to identify error type, and hal_uart_error_callback() user callback is executed.
603
604 -@- In the Half duplex communication, it is forbidden to run the transmit
605 and receive process in parallel, the UART state hal_uart_state_busy_tx_rx can't be useful.
