bogdanm	0:9b334a45a8ff	20	[..]
bogdanm	0:9b334a45a8ff	21	The USART HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	22
bogdanm	0:9b334a45a8ff	23	(#) Declare a USART_HandleTypeDef handle structure.
bogdanm	0:9b334a45a8ff	24	(#) Initialize the USART low level resources by implement the HAL_USART_MspInit ()API:
bogdanm	0:9b334a45a8ff	25	(##) Enable the USARTx interface clock.
bogdanm	0:9b334a45a8ff	26	(##) USART pins configuration:
bogdanm	0:9b334a45a8ff	27	(+++) Enable the clock for the USART GPIOs.
bogdanm	0:9b334a45a8ff	28	(+++) Configure these USART pins as alternate function pull-up.
bogdanm	0:9b334a45a8ff	29	(##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
bogdanm	0:9b334a45a8ff	30	HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
bogdanm	0:9b334a45a8ff	31	(+++) Configure the USARTx interrupt priority.
bogdanm	0:9b334a45a8ff	32	(+++) Enable the NVIC USART IRQ handle.
bogdanm	0:9b334a45a8ff	33	(@) The specific USART interrupts (Transmission complete interrupt,
bogdanm	0:9b334a45a8ff	34	RXNE interrupt and Error Interrupts) will be managed using the macros
bogdanm	0:9b334a45a8ff	35	__HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
bogdanm	0:9b334a45a8ff	36	(##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
bogdanm	0:9b334a45a8ff	37	HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
bogdanm	0:9b334a45a8ff	38	(+++) Declare a DMA handle structure for the Tx/Rx stream.
bogdanm	0:9b334a45a8ff	39	(+++) Enable the DMAx interface clock.
bogdanm	0:9b334a45a8ff	40	(+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm	0:9b334a45a8ff	41	(+++) Configure the DMA Tx/Rx Stream.

bogdanm	0:9b334a45a8ff	43	(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
bogdanm	0:9b334a45a8ff	44
bogdanm	0:9b334a45a8ff	45	(#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
bogdanm	0:9b334a45a8ff	46	flow control and Mode(Receiver/Transmitter) in the husart Init structure.

bogdanm	0:9b334a45a8ff	154	the possible USART frame formats are as listed in the following table:

bogdanm	0:9b334a45a8ff	305	This subsection provides a set of functions allowing to manage the USART synchronous
bogdanm	0:9b334a45a8ff	306	data transfers.
bogdanm	0:9b334a45a8ff	307
bogdanm	0:9b334a45a8ff	308	[..] The USART supports master mode only: it cannot receive or send data related to an input
bogdanm	0:9b334a45a8ff	309	clock (SCLK is always an output).
bogdanm	0:9b334a45a8ff	310
bogdanm	0:9b334a45a8ff	311	(#) There are two modes of transfer:
bogdanm	0:9b334a45a8ff	312	(++) Blocking mode: The communication is performed in polling mode.
bogdanm	0:9b334a45a8ff	313	The HAL status of all data processing is returned by the same function
bogdanm	0:9b334a45a8ff	314	after finishing transfer.
bogdanm	0:9b334a45a8ff	315	(++) No-Blocking mode: The communication is performed using Interrupts
bogdanm	0:9b334a45a8ff	316	or DMA, These API's return the HAL status.
bogdanm	0:9b334a45a8ff	317	The end of the data processing will be indicated through the
bogdanm	0:9b334a45a8ff	318	dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
bogdanm	0:9b334a45a8ff	319	using DMA mode.

bogdanm	0:9b334a45a8ff	321	will be executed respectivelly at the end of the transmit or Receive process
bogdanm	0:9b334a45a8ff	322	The HAL_USART_ErrorCallback()user callback will be executed when a communication error is detected.
bogdanm	0:9b334a45a8ff	323
