+ ==============================================================================
+ ##### DAC Peripheral features #####
+ ==============================================================================
+ [..]
+ *** DAC Channels ***
+ ====================
+ [..]
+ STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters.
+ STM32F05x devices have one converter (channel1)
+ STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2)
+
+ When 2 converters are present (i.e. channel1 & channel2) they
+ can be used independently or simultaneously (dual mode):
+ (#) DAC channel1 with DAC_OUT1 (PA4) as output
+ (#) DAC channel2 with DAC_OUT2 (PA5) as output
+
+ *** DAC Triggers ***
+ ====================
+ [..]
+ Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
+ and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
+ [..]
+ Digital to Analog conversion can be triggered by:
+ (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
+ The used pin (GPIOx_PIN_9) must be configured in input mode.
+
+ (#) Timers TRGO: TIM2, TIM3, TIM6, and TIM15
+ (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T3_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.
+
+ *** GPIO configurations guidelines ***
+ =====================
+ [..]
+ When a DAC channel is used (ex channel1 on PA4) and the other is not
+ (ex channel1 on PA5 is configured in Analog and disabled).
+ Channel1 may disturb channel2 as coupling effect.
+ Note that there is no coupling on channel2 as soon as channel2 is turned on.
+ Coupling on adjacent channel could be avoided as follows:
+ when unused PA5 is configured as INPUT PULL-UP or DOWN.
+ PA5 is configured in ANALOG just before it is turned on.
+
+ *** DAC wave generation feature ***
+ ===================================
+ [..]
+ Both DAC channels can be used to generate
+ (#) Noise wave
+ (#) Triangle wave
+
+ *** 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 correspondance ***
+ ================================================
+ [..]
+ 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 request can be generated when an external trigger (but not
+ a software trigger) occurs if DMA1 requests are enabled using
+ HAL_DAC_Start_DMA()
+ [..]
+ DMA1 requests are mapped as following:
+ (#) DAC channel1 : mapped on DMA1 channel3 which must be
+ already configured
+ (#) DAC channel2 : mapped on DMA1 channel4 which must be
+ already configured
+
+ (@) For Dual mode and specific signal (Triangle and noise) generation please
+ refer to Extended Features Driver description
+ STM32F0 devices with one channel (one converting capability) does not
+ support Dual mode and specific signal (Triangle and noise) generation.
+
+ ##### 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, 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 transferred at each end of conversion
+ (+) At the middle of data transfer HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+ function is executed and user can add his own code by customization of function pointer
+ HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+ (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+ function is executed and user can add his own code by customization of function pointer
+ HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2()
+ (+) 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
+ (+) In case of DMA underrun, DAC interruption triggers and execute internal function HAL_DAC_IRQHandler.
+ HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2()
+ function is executed and user can add his own code by customization of function pointer
+ HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2() and
+ add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1()
+ (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
+
+ *** Callback registration ***
+ =============================================
+ [..]
+ The compilation define USE_HAL_DAC_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+
+ Use Functions @ref HAL_DAC_RegisterCallback() to register a user callback,
+ it allows to register following callbacks:
+ (+) ConvCpltCallbackCh1 : callback when a half transfer is completed on Ch1.
+ (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
+ (+) ErrorCallbackCh1 : callback when an error occurs on Ch1.
+ (+) DMAUnderrunCallbackCh1 : callback when an error occurs on Ch1.
+ (+) ConvCpltCallbackCh2 : callback when a half transfer is completed on Ch2.
+ (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
+ (+) ErrorCallbackCh2 : callback when an error occurs on Ch2.
+ (+) DMAUnderrunCallbackCh2 : callback when an error occurs on Ch2.
+ (+) MspInitCallback : DAC MspInit.
+ (+) MspDeInitCallback : DAC MspdeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+ Use function @ref HAL_DAC_UnRegisterCallback() to reset a callback to the default
+ weak (surcharged) function. It allows to reset following callbacks:
+ (+) ConvCpltCallbackCh1 : callback when a half transfer is completed on Ch1.
+ (+) ConvHalfCpltCallbackCh1 : callback when a transfer is completed on Ch1.
+ (+) ErrorCallbackCh1 : callback when an error occurs on Ch1.
+ (+) DMAUnderrunCallbackCh1 : callback when an error occurs on Ch1.
+ (+) ConvCpltCallbackCh2 : callback when a half transfer is completed on Ch2.
+ (+) ConvHalfCpltCallbackCh2 : callback when a transfer is completed on Ch2.
+ (+) ErrorCallbackCh2 : callback when an error occurs on Ch2.
+ (+) DMAUnderrunCallbackCh2 : callback when an error occurs on Ch2.
+ (+) MspInitCallback : DAC MspInit.
+ (+) MspDeInitCallback : DAC MspdeInit.
+ (+) All Callbacks
+ This function) takes as parameters the HAL peripheral handle and the Callback ID.
+
+ By default, after the @ref HAL_DAC_Init and if the state is HAL_DAC_STATE_RESET
+ all callbacks are reset to the corresponding legacy weak (surcharged) functions.
+ Exception done for MspInit and MspDeInit callbacks that are respectively
+ reset to the legacy weak (surcharged) functions in the @ref HAL_DAC_Init
+ and @ref HAL_DAC_DeInit only when these callbacks are null (not registered beforehand).
+ If not, MspInit or MspDeInit are not null, the @ref HAL_DAC_Init and @ref HAL_DAC_DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ Callbacks can be registered/unregistered in READY state only.
+ Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
+ in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
+ during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using @ref HAL_DAC_RegisterCallback before calling @ref HAL_DAC_DeInit
+ or @ref HAL_DAC_Init function.
+
+ When The compilation define USE_HAL_DAC_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registering feature is not available
+ and weak (surcharged) callbacks are used.
+
+ *** 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
