+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The USART HAL driver can be used as follows:
+
+    (#) Declare a USART_HandleTypeDef handle structure.
+    (#) Initialize the USART low level resources by implementing the HAL_USART_MspInit () API:
+        (##) Enable the USARTx interface clock.
+        (##) USART pins configuration:
+             (+++) Enable the clock for the USART GPIOs.
+             (+++) Configure these USART pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_USART_Transmit_IT(),
+             HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
+             (+++) Configure the USARTx interrupt priority.
+             (+++) Enable the NVIC USART IRQ handle.
+        (##) DMA Configuration if you need to use DMA process (HAL_USART_Transmit_DMA()
+             HAL_USART_Receive_IT() and HAL_USART_TransmitReceive_IT() APIs):
+             (+++) Declare a DMA handle structure for the Tx/Rx stream.
+             (+++) Enable the DMAx interface clock.
+             (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
+             (+++) Configure the DMA Tx/Rx Stream.
+             (+++) Associate the initialized DMA handle to the USART DMA Tx/Rx handle.
+             (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx Stream.
+
+    (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware
+        flow control and Mode(Receiver/Transmitter) in the husart Init structure.
+
+    (#) Initialize the USART registers by calling the HAL_USART_Init() API:
+        (++) These APIs configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
+             by calling the customized HAL_USART_MspInit(&husart) API.
+
+        -@@- The specific USART interrupts (Transmission complete interrupt,
+             RXNE interrupt and Error Interrupts) will be managed using the macros
+             __HAL_USART_ENABLE_IT() and __HAL_USART_DISABLE_IT() inside the transmit and receive process.
+
+    (#) Three operation modes are available within this driver :
+

+     =================================

+       (+) Send an amount of data in blocking mode using HAL_USART_Transmit()

+    This subsection provides a set of functions allowing to manage the USART synchronous
+    data transfers.
+
+  [..]
+    The USART supports master mode only: it cannot receive or send data related to an input
+    clock (SCLK is always an output).
+
+    (#) There are two modes of transfer:
+        (++) Blocking mode: The communication is performed in polling mode.
+             The HAL status of all data processing is returned by the same function
+             after finishing transfer.
+        (++) No-Blocking mode: The communication is performed using Interrupts
+             or DMA, These API's return the HAL status.
+             The end of the data processing will be indicated through the
+             dedicated USART IRQ when using Interrupt mode or the DMA IRQ when
+             using DMA mode.
+             The HAL_USART_TxCpltCallback(), HAL_USART_RxCpltCallback() and HAL_USART_TxRxCpltCallback()
+              user callbacks
+             will be executed respectively at the end of the transmit or Receive process
+             The HAL_USART_ErrorCallback() user callback will be executed when a communication
+             error is detected
+
+    (#) Blocking mode APIs are :
+        (++) HAL_USART_Transmit() in simplex mode
+        (++) HAL_USART_Receive() in full duplex receive only
+        (++) HAL_USART_TransmitReceive() in full duplex mode
