==============================================================================
##### 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_PIN_9) using DAC_TRIGGER_EXT_IT9.
The used pin (GPIOx_PIN_9) 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;
Or
An output switch
(in STM32F303x4, STM32F303x6, STM32F303x8
c, STM32F334x6, STM32F334x8
& STM32F334xx).
To enable, the output switch
sConfig.DAC_OutputSwitch = DAC_OUTPUTSWITCH_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 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 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 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
f3 hal and cmsis update
2018-03-02 03:34:09 +00:00
(+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3U * 868U) / 4095U = 0.7V
added f3 hal lib, cmsis and usb device lib
2017-01-05 14:45:54 +00:00
*** 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
(@) 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
(+) 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()
*** 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
