bogdanm	0:9b334a45a8ff	18	[..]
bogdanm	0:9b334a45a8ff	19	The USART HAL driver can be used as follows:
bogdanm	0:9b334a45a8ff	20
bogdanm	0:9b334a45a8ff	21	(#) Declare a USART_HandleTypeDef handle structure.
bogdanm	0:9b334a45a8ff	22	(#) Initialize the USART low level resources by implementing the HAL_USART_MspInit() API:
bogdanm	0:9b334a45a8ff	23	(##) Enable the USARTx interface clock.
bogdanm	0:9b334a45a8ff	24	(##) USART pins configuration:
bogdanm	0:9b334a45a8ff	25	(+++) Enable the clock for the USART GPIOs.
bogdanm	0:9b334a45a8ff	26	(+++) Configure the USART pins (TX as alternate function pull-up, RX as alternate function Input).
bogdanm	0:9b334a45a8ff	27	(##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),

bogdanm	0:9b334a45a8ff	35	(+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
bogdanm	0:9b334a45a8ff	36	(+++) Configure the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	37	(+++) Associate the initilalized DMA handle to the USART DMA Tx/Rx handle.
bogdanm	0:9b334a45a8ff	38	(+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
bogdanm	0:9b334a45a8ff	39	(+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle
bogdanm	0:9b334a45a8ff	40	(used for last byte sending completion detection in DMA non circular mode)

bogdanm	0:9b334a45a8ff	43	flow control and Mode(Receiver/Transmitter) in the husart Init structure.
bogdanm	0:9b334a45a8ff	44
bogdanm	0:9b334a45a8ff	45	(#) Initialize the USART registers by calling the HAL_USART_Init() API:
bogdanm	0:9b334a45a8ff	46	(++) These APIs configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
