##### DAC Peripheral features #####
|
|
==============================================================================
|
|
[..]
|
|
*** DAC Channels ***
|
|
====================
|
|
[..]
|
|
STM32F7 devices integrates two 12-bit Digital Analog Converters that 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_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 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 DMA1 requests are enabled using HAL_DAC_Start_DMA().
|
|
DMA1 requests are mapped as following:
|
|
(#) DAC channel1 mapped on DMA1 Stream5 channel7 which must be
|
|
already configured
|
|
(#) DAC channel2 mapped on DMA1 Stream6 channel7 which must be
|
|
already configured
|
|
|
|
[..]
|
|
(@) For Dual mode and specific signal (Triangle and noise) generation please
|
|
refer to Extended Features Driver description
|
|
|
|
##### 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
|
|
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_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 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 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 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 HAL_DAC_Init
|
|
and HAL_DAC_DeInit only when these callbacks are null (not registered beforehand).
|
|
If not, MspInit or MspDeInit are not null, the HAL_DAC_Init and 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 HAL_DAC_RegisterCallback before calling HAL_DAC_DeInit
|
|
or 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.
|
|
|
