-  ==============================================================================
-                        ##### How to use this driver #####
-  ==============================================================================
-  [..]
-    The IRDA HAL driver can be used as follows:
-
-    (#) Declare a IRDA_HandleTypeDef handle structure (eg. IRDA_HandleTypeDef hirda).
-    (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API
-        in setting the associated USART or UART in IRDA mode:
-        (++) Enable the USARTx/UARTx interface clock.
-        (++) USARTx/UARTx pins configuration:
-            (+++) Enable the clock for the USARTx/UARTx GPIOs.
-            (+++) Configure these USARTx/UARTx pins (TX as alternate function pull-up, RX as alternate function Input).
-        (++) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
-             and HAL_IRDA_Receive_IT() APIs): 
-            (+++) Configure the USARTx/UARTx interrupt priority.
-            (+++) Enable the NVIC USARTx/UARTx IRQ handle.            
-            (+++) The specific IRDA interrupts (Transmission complete interrupt,
-                  RXNE interrupt and Error Interrupts) will be managed using the macros
-                  __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_DISABLE_IT() inside the transmit and receive process.
-                
-        (++) DMA Configuration if you need to use DMA process (HAL_IRDA_Transmit_DMA()
-             and HAL_IRDA_Receive_DMA() APIs):
-            (+++) Declare a DMA handle structure for the Tx/Rx channel.
-            (+++) Enable the DMAx interface clock.
-            (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
-            (+++) Configure the DMA Tx/Rx channel.
-            (+++) Associate the initialized DMA handle to the IRDA DMA Tx/Rx handle.
-            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the DMA Tx/Rx channel.
-
-    (#) Program the Baud Rate, Word Length and Parity and Mode(Receiver/Transmitter),
-        the normal or low power mode and the clock prescaler in the hirda handle Init structure.
-
-    (#) Initialize the IRDA registers by calling the HAL_IRDA_Init() API:
-        (++) This API configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
-             by calling the customized HAL_IRDA_MspInit() API.
-        
-         -@@- The specific IRDA interrupts (Transmission complete interrupt,
-             RXNE interrupt and Error Interrupts) will be managed using the macros
-             __HAL_IRDA_ENABLE_IT() and __HAL_IRDA_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_IRDA_Transmit()

-     *** Interrupt mode IO operation ***
-     ===================================
-     [..]
-       (+) Send an amount of data in non-blocking mode using HAL_IRDA_Transmit_IT()

-       (+) Receive an amount of data in non-blocking mode using HAL_IRDA_Receive_IT()

-
-     *** DMA mode IO operation ***
-     ==============================
-     [..]
-       (+) Send an amount of data in non-blocking mode (DMA) using HAL_IRDA_Transmit_DMA()
-       (+) At transmission half of transfer HAL_IRDA_TxHalfCpltCallback() is executed and user can

-  [..]
-    IrDA is a half duplex communication protocol. If the Transmitter is busy, any data
-    on the IrDA receive line will be ignored by the IrDA decoder and if the Receiver
-    is busy, data on the TX from the USART to IrDA will not be encoded by IrDA.
-    While receiving data, transmission should be avoided as the data to be transmitted
-    could be corrupted.
-
-    (#) There are two mode 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.
-        (++) Non-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 IRDA IRQ when using Interrupt mode or the DMA IRQ when
-             using DMA mode.
-             The HAL_IRDA_TxCpltCallback(), HAL_IRDA_RxCpltCallback() user callbacks
-             will be executed respectively at the end of the Transmit or Receive process
-             The HAL_IRDA_ErrorCallback() user callback will be executed when a communication error is detected
-

-    (#) For Abort services based on interrupts (HAL_IRDA_Abortxxx_IT), a set of Abort Complete Callbacks are provided:

-    (#) In Non-Blocking mode transfers, possible errors are split into 2 categories.
-        Errors are handled as follows :
-       (++) Error is considered as Recoverable and non blocking : Transfer could go till end, but error severity is 
-            to be evaluated by user : this concerns Frame Error, Parity Error or Noise Error in Interrupt mode reception .
-            Received character is then retrieved and stored in Rx buffer, Error code is set to allow user to identify error type,
-            and HAL_IRDA_ErrorCallback() user callback is executed. Transfer is kept ongoing on IRDA side.
-            If user wants to abort it, Abort services should be called by user.
-       (++) Error is considered as Blocking : Transfer could not be completed properly and is aborted.
-            This concerns Overrun Error In Interrupt mode reception and all errors in DMA mode.
-            Error code is set to allow user to identify error type, and HAL_IRDA_ErrorCallback() user callback is executed.
