- ##### DAC Peripheral features #####
- ==============================================================================
- [..]
- *** DAC Channels ***
- ====================
- [..]
- STM32H7 devices integrate two 12-bit Digital Analog Converters
-
- The 2 converters (i.e. channel1 & channel2)
- can be used independently or simultaneously (dual mode):
- (#) DAC channel1 with DAC_OUT1 (PA4) as output or connected to on-chip
- peripherals (ex. OPAMPs, comparators).
- (#) DAC channel2 with DAC_OUT2 (PA5) as output or connected to on-chip
- peripherals (ex. OPAMPs, comparators).
-
- *** 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: TIM1, TIM2, TIM4, TIM5, TIM6, TIM7, TIM8, TIM15, TIM23 and TIM24
- (DAC_TRIGGER_T1_TRGO, DAC_TRIGGER_T2_TRGO...)
-
- (#) Low Power Timers TRGO: LPTIM1, LPTIM2 and LPTIM3
- (DAC_TRIGGER_LPTIM1_OUT, DAC_TRIGGER_LPTIM2_OUT)
-
- (#) High Resolution Timer TRGO: HRTIM1
- (DAC_TRIGGER_HR1_TRGO1, DAC_TRIGGER_HR1_TRGO2)
-
- (#) 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 connect feature ***
- ===============================
- [..]
- Each DAC channel can be connected internally.
- To connect, use
- sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_INTERNAL;
- or
- sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_BOTH;
-
- *** GPIO configurations guidelines ***
- =====================
- [..]
- When a DAC channel is used (ex channel1 on PA4) and the other is not
- (ex channel2 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 Sample and Hold feature ***
- ========================
- [..]
- For each converter, 2 modes are supported: normal mode and
- "sample and hold" mode (i.e. low power mode).
- In the sample and hold mode, the DAC core converts data, then holds the
- converted voltage on a capacitor. When not converting, the DAC cores and
- buffer are completely turned off between samples and the DAC output is
- tri-stated, therefore reducing the overall power consumption. A new
- stabilization period is needed before each new conversion.
-
- The sample and hold allow setting internal or external voltage @
- low power consumption cost (output value can be at any given rate either
- by CPU or DMA).
-
- The Sample and hold block and registers uses either LSI & run in
- several power modes: run mode, sleep mode, low power run, low power sleep
- mode & stop1 mode.
-
- Low power stop1 mode allows only static conversion.
-
- To enable Sample and Hold mode
- Enable LSI using HAL_RCC_OscConfig with RCC_OSCILLATORTYPE_LSI &
- RCC_LSI_ON parameters.
-
- Use DAC_InitStructure.DAC_SampleAndHold = DAC_SAMPLEANDHOLD_ENABLE;
- & DAC_ChannelConfTypeDef.DAC_SampleAndHoldConfig.DAC_SampleTime,
- DAC_HoldTime & DAC_RefreshTime;
-
- *** DAC calibration feature ***
- ===================================
- [..]
- (#) The 2 converters (channel1 & channel2) provide calibration capabilities.
- (++) Calibration aims at correcting some offset of output buffer.
- (++) The DAC uses either factory calibration settings OR user defined
- calibration (trimming) settings (i.e. trimming mode).
- (++) The user defined settings can be figured out using self calibration
- handled by HAL_DACEx_SelfCalibrate.
- (++) HAL_DACEx_SelfCalibrate:
- (+++) Runs automatically the calibration.
- (+++) Enables the user trimming mode
- (+++) Updates a structure with trimming values with fresh calibration
- results.
- The user may store the calibration results for larger
- (ex monitoring the trimming as a function of temperature
- for instance)
-
- *** 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 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
- [..]
- VREF+ 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 DMA request can be generated when an external trigger (but not a software trigger)
- occurs if DMA requests are enabled using HAL_DAC_Start_DMA().
- DMA requests are mapped as following:
- (#) DAC channel1: mapped on DMA_REQUEST_DAC1_CH1
- (#) DAC channel2: mapped on DMA_REQUEST_DAC1_CH2
-
- [..]
- (@) For Dual mode and specific signal (Triangle and noise) generation please
- refer to Extended Features Driver description
-
- ##### How to use this driver #####
- ==============================================================================

- 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.
-

- [..]
- (+) 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
- First issued trigger will start the conversion of the value previously set by HAL_DAC_SetValue().
- (+) 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_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 underrun 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 underrun 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 underrun 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 underrun 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.
