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 + (+) __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 + + @endverbatim + ****************************************************************************** + * @attention + * + *
