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	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	45	(#) Initialize the USART registers by calling the HAL_USART_Init() API:
