+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    The I2C HAL driver can be used as follows:
+
+    (#) Declare a I2C_HandleTypeDef handle structure, for example:
+        I2C_HandleTypeDef  hi2c;
+
+    (#)Initialize the I2C low level resources by implement the HAL_I2C_MspInit() API:
+        (##) Enable the I2Cx interface clock
+        (##) I2C pins configuration
+            (+++) Enable the clock for the I2C GPIOs
+            (+++) Configure I2C pins as alternate function open-drain
+        (##) NVIC configuration if you need to use interrupt process
+            (+++) Configure the I2Cx interrupt priority
+            (+++) Enable the NVIC I2C IRQ Channel
+        (##) DMA Configuration if you need to use DMA process
+            (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
+            (+++) Enable the DMAx interface clock using
+            (+++) Configure the DMA handle parameters
+            (+++) Configure the DMA Tx or Rx Stream
+            (+++) Associate the initialized DMA handle to the hi2c DMA Tx or Rx handle
+            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
+                  the DMA Tx or Rx Stream
+
+    (#) Configure the Communication Speed, Duty cycle, Addressing mode, Own Address1,
+        Dual Addressing mode, Own Address2, General call and Nostretch mode in the hi2c Init structure.
+
+    (#) Initialize the I2C registers by calling the HAL_I2C_Init(), configures also the low level Hardware
+        (GPIO, CLOCK, NVIC...etc) by calling the customized HAL_I2C_MspInit(&hi2c) API.
+
+    (#) To check if target device is ready for communication, use the function HAL_I2C_IsDeviceReady()
+
+    (#) For I2C IO and IO MEM operations, three operation modes are available within this driver :
+
