+
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+  (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
+       (##) Enable the ADC interface clock using __HAL_RCC_ADC_CLK_ENABLE()
+       (##) ADC pins configuration
+             (+++) Enable the clock for the ADC GPIOs using the following function:
+                   __HAL_RCC_GPIOx_CLK_ENABLE()  
+             (+++) Configure these ADC pins in analog mode using HAL_GPIO_Init()

+    *** Configuration of ADC, groups regular/injected, channels parameters ***

+
+     *** DMA mode IO operation ***    
+     ==============================
+     [..]    
+       (+) Start the ADC peripheral using HAL_ADC_Start_DMA(), at this stage the user specify the length 
+           of data to be transferred at each end of conversion
