+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The IRDA HAL driver can be used as follows:
+    
+    (#) Declare a IRDA_HandleTypeDef handle structure.
+    (#) Initialize the IRDA low level resources by implementing the HAL_IRDA_MspInit() API:
+        (##) Enable the USARTx interface clock.
+        (##) IRDA pins configuration:
+            (+++) Enable the clock for the IRDA GPIOs.
+            (+++) Configure these IRDA pins as alternate function pull-up.
+        (##) NVIC configuration if you need to use interrupt process (HAL_IRDA_Transmit_IT()
+             and HAL_IRDA_Receive_IT() APIs):
+            (+++) Configure the USARTx interrupt priority.
+            (+++) Enable the NVIC USART IRQ handle.
+        (##) 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 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 IRDA 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, Parity, IrDA Mode, Prescaler 
+        and Mode(Receiver/Transmitter) in the hirda 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 :
+             
+    *** Polling mode IO operation ***
+    =================================
+    [..]    
+      (+) Send an amount of data in blocking mode using HAL_IRDA_Transmit() 
+      (+) Receive an amount of data in blocking mode using HAL_IRDA_Receive()
+       
+    *** Interrupt mode IO operation ***    
+    ===================================
+    [..]    
+      (+) Send an amount of data in non blocking mode using HAL_IRDA_Transmit_IT() 
+      (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode using HAL_IRDA_Receive_IT() 
+      (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_RxCpltCallback                                      
+      (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_ErrorCallback
+
+    *** DMA mode IO operation ***    
+    =============================
+    [..]
+      (+) Send an amount of data in non blocking mode (DMA) using HAL_IRDA_Transmit_DMA() 
+      (+) At transmission end of transfer HAL_IRDA_TxCpltCallback is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_TxCpltCallback
+      (+) Receive an amount of data in non blocking mode (DMA) using HAL_IRDA_Receive_DMA() 
+      (+) At reception end of transfer HAL_IRDA_RxCpltCallback is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_RxCpltCallback                                      
+      (+) In case of transfer Error, HAL_IRDA_ErrorCallback() function is executed and user can 
+           add his own code by customization of function pointer HAL_IRDA_ErrorCallback    
+
+    *** IRDA HAL driver macros list ***
+    ===================================
+    [..]
+      Below the list of most used macros in IRDA HAL driver.
+       
+     (+) __HAL_IRDA_ENABLE: Enable the IRDA peripheral 
+     (+) __HAL_IRDA_DISABLE: Disable the IRDA peripheral     
+     (+) __HAL_IRDA_GET_FLAG : Checks whether the specified IRDA flag is set or not

+    This subsection provides a set of functions allowing to initialize the USARTx or the UARTy 
+    in IrDA mode.
+      (+) For the asynchronous mode only these parameters can be configured: 
+        (++) BaudRate
+        (++) WordLength 
+        (++) Parity: If the parity is enabled, then the MSB bit of the data written
+             in the data register is transmitted but is changed by the parity bit.
+             Depending on the frame length defined by the M bit (8-bits or 9-bits),
+             please refer to Reference manual for possible IRDA frame formats.
+        (++) Prescaler: A pulse of width less than two and greater than one PSC period(s) may or may
+             not be rejected. The receiver set up time should be managed by software. The IrDA physical layer
+             specification specifies a minimum of 10 ms delay between transmission and 
+             reception (IrDA is a half duplex protocol).
+        (++) Mode: Receiver/transmitter modes
+        (++) IrDAMode: the IrDA can operate in the Normal mode or in the Low power mode.
+    [..]
+    The HAL_IRDA_Init() API follows IRDA configuration procedures (details for the procedures
+    are available in reference manual).

+    This subsection provides a set of functions allowing to manage the IRDA data transfers.
+    [..]
+    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 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 APIs 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
+
+    (#) Blocking mode API's are :
