-  * @brief   CAN HAL module driver.
-  *          This file provides firmware functions to manage the following 
-  *          functionalities of the Controller Area Network (CAN) peripheral:
-  *           + Initialization and de-initialization functions 
-  *           + IO operation functions
-  *           + Peripheral Control functions
-  *           + Peripheral State and Error functions

-  ==============================================================================    
-                        ##### How to use this driver #####
-  ==============================================================================
-    [..]            
-      (#) Enable the CAN controller interface clock using __HAL_RCC_CAN1_CLK_ENABLE(); 
-       
-      (#) CAN pins configuration
-        (++) Enable the clock for the CAN GPIOs using the following function:
-             __HAL_RCC_GPIOx_CLK_ENABLE();   
-        (++) Connect and configure the involved CAN pins to AF9 using the 
-              following function HAL_GPIO_Init(); 
-              
-      (#) Initialise and configure the CAN using HAL_CAN_Init() function.   
-                 
-      (#) Transmit the desired CAN frame using HAL_CAN_Transmit() function.
-           
-      (#) Receive a CAN frame using HAL_CAN_Receive() function.
-
-     *** Polling mode IO operation ***
-     =================================
-     [..]    
-       (+) Start the CAN peripheral transmission and wait the end of this operation 
-           using HAL_CAN_Transmit(), at this stage user can specify the value of timeout
-           according to his end application
-       (+) Start the CAN peripheral reception and wait the end of this operation 
-           using HAL_CAN_Receive(), at this stage user can specify the value of timeout
-           according to his end application 
-       
-     *** Interrupt mode IO operation ***    
-     ===================================
-     [..]    
-       (+) Start the CAN peripheral transmission using HAL_CAN_Transmit_IT()
-       (+) Start the CAN peripheral reception using HAL_CAN_Receive_IT()         
-       (+) Use HAL_CAN_IRQHandler() called under the used CAN Interrupt subroutine
-       (+) At CAN end of transmission HAL_CAN_TxCpltCallback() function is executed and user can 
-            add his own code by customization of function pointer HAL_CAN_TxCpltCallback 
-       (+) In case of CAN Error, HAL_CAN_ErrorCallback() function is executed and user can 
-            add his own code by customization of function pointer HAL_CAN_ErrorCallback
- 
-     *** CAN HAL driver macros list ***
-     ============================================= 
-     [..]
-       Below the list of most used macros in CAN HAL driver.
-       
-      (+) __HAL_CAN_ENABLE_IT: Enable the specified CAN interrupts
-      (+) __HAL_CAN_DISABLE_IT: Disable the specified CAN interrupts
-      (+) __HAL_CAN_GET_IT_SOURCE: Check if the specified CAN interrupt source is enabled or disabled
-      (+) __HAL_CAN_CLEAR_FLAG: Clear the CAN's pending flags
-      (+) __HAL_CAN_GET_FLAG: Get the selected CAN's flag status
-      
-     [..] 
-      (@) You can refer to the CAN HAL driver header file for more useful macros
