  ==============================================================================
                      ##### DAC Peripheral features #####
  ==============================================================================
    [..]        
      *** DAC Channels ***
      ====================  
    [..]  
    The device integrates up to 3 12-bit Digital Analog Converters that can 
    be used independently or simultaneously (dual mode):
      (#) DAC1 channel1 with DAC1_OUT1 (PA4) as output
      (#) DAC1 channel2 with DAC1_OUT2 (PA5) as output 
          (for STM32F3 devices having 2 channels on DAC1)
      (#) DAC2 channel1 with DAC2_OUT1 (PA6) as output 
          (for STM32F3 devices having 2 DAC)

      *** DAC Triggers ***
      ====================
    [..]
    Digital to Analog conversion can be non-triggered using DAC_Trigger_None
    and DAC1_OUT1/DAC1_OUT2/DAC2_OUT1 is available once writing to DHRx register. 
    [..] 
    Digital to Analog conversion can be triggered by:
      (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
          The used pin (GPIOx_Pin9) must be configured in input mode.
  
      (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8 
          (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
  
      (#) Software using DAC_Trigger_Software
  
      *** DAC Buffer mode feature ***
      =============================== 
      [..] 
      Each DAC channel integrates an output buffer that can be used to 
      reduce the output impedance, and to drive external loads directly
      without having to add an external operational amplifier.
      To enable, the output buffer use  
      sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
      [..]           
      (@) Refer to the device datasheet for more details about output 
          impedance value with and without output buffer.
            
       *** DAC wave generation feature ***
       =================================== 
       [..]     
       Both DAC channels of DAC1 can be used to generate
       note that wave generation is not available in DAC2.
         (#) Noise wave
         (#) Triangle wave
      
       Wave generation is NOT available in DAC2.

       *** DAC data format ***
       =======================
       [..]   
       The DAC data format can be:
         (#) 8-bit right alignment using DAC_ALIGN_8B_R
         (#) 12-bit left alignment using DAC_ALIGN_12B_L
         (#) 12-bit right alignment using DAC_ALIGN_12B_R
  
       *** DAC data value to voltage correspondence ***  
       ================================================ 
       [..] 
       The analog output voltage on each DAC channel pin is determined
       by the following equation: 
       DAC_OUTx = VREF+ * DOR / 4095
       with  DOR is the Data Output Register
          VEF+ is the input voltage reference (refer to the device datasheet)
        e.g. To set DAC_OUT1 to 0.7V, use
          Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
  
       *** DMA requests  ***
       =====================
       [..]    
       A DMA1 or DMA2 request can be generated when an external trigger 
       (but not a software trigger) occurs if DMA1 or DMA2 requests are 
       enabled using HAL_DAC_Start_DMA()
       [..]
       DMA1 requests are mapped as following:
         (#) DAC1 channel1: mapped either on
             - DMA1 channel3 
             - or DMA2 channel3 (for STM32F3 devices having 2 DMA)
             which must be already configured
         (#) DAC1 channel2: 
             (for STM32F3 devices having 2 channels on DAC1)
             mapped either on
             - DMA1 channel4 
             - or DMA2 channel4 (for STM32F3 devices having 2 DMA)
             which must be already configured
      
         (#) DAC2 channel1: mapped either on 
             (for STM32F3 devices having 2 DAC)
             - DMA1 channel4 
             - or DMA2 channel4 (for STM32F3 devices having 2 DMA)
             which must be already configured

                      ##### How to use this driver #####
  ==============================================================================
    [..]          
      (+) DAC APB clock must be enabled to get write access to DAC
          registers using HAL_DAC_Init()
      (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
      (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
      (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA 
          functions

     *** Polling mode IO operation ***
     =================================
     [..]    
       (+) Start the DAC peripheral using HAL_DAC_Start() 
       (+) To read the DAC last data output value value, use the HAL_DAC_GetValue() function.
       (+) Stop the DAC peripheral using HAL_DAC_Stop()
       
     *** DMA mode IO operation ***    
     ==============================
     [..]    
       (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length 
           of data to be transfered at each end of conversion 
       (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1()or HAL_DAC_ConvCpltCallbackCh2()  
           function is executed and user can add his own code by customization of function pointer 
           HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
       (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can 
            add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
       (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()

     *** Dual mode operation ***    
     ==============================   
     [..]
      (+) When Dual mode is enabled 
          (i.e DAC1 Channel1 and DAC1 Channel2 are used simultaneously) 
          (for STM32F3 devices having 2 channels on DAC1).
          Use HAL_DACEx_DualGetValue() to get digital data to be converted and use
          HAL_DACEx_DualSetValue() to set digital value to converted simultaneously 
          in Channel 1 and Channel 2.  

     *** Wave generation operation ***    
     ==============================   
     [..]
      (+) Use HAL_DACEx_TriangleWaveGenerate to generate Triangle signal.
      (+) Use HAL_DACEx_NoiseWaveGenerate to generate Noise signal.
   
          Wave generation is NOT available in DAC2.
                    
     *** DAC HAL driver macros list ***
     ============================================= 
     [..]
       Below the list of most used macros in DAC HAL driver.
       
      (+) __HAL_DAC_ENABLE : Enable the DAC peripheral
      (+) __HAL_DAC_DISABLE : Disable the DAC peripheral
      (+) __HAL_DAC_CLEAR_FLAG: Clear the DAC's pending flags
      (+) __HAL_DAC_GET_FLAG: Get the selected DAC's flag status 
      
     [..]
      (@) You can refer to the DAC HAL driver header file for more useful macros
