******************************************************************************
* @file stm32f4xx_dac.c
* @author MCD Application Team
* @version V1.4.0
* @date 04-August-2014
* @brief This file provides firmware functions to manage the following
* functionalities of the Digital-to-Analog Converter (DAC) peripheral:
* + DAC channels configuration: trigger, output buffer, data format
* + DMA management
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### DAC Peripheral features #####
===============================================================================
[..]
*** DAC Channels ***
====================
[..]
The device 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
using DAC_SetChannel1Data() / DAC_SetChannel2Data() functions.
[..]
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...)
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
(#) 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
DAC_InitStructure.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 using DAC_WaveGeneration_Noise
(#) Triangle wave using DAC_WaveGeneration_Triangle
-@- Wave generation can be disabled using DAC_WaveGeneration_None
*** 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
VEF+ is the input voltage reference (refer to the device datasheet)
e.g. To set DAC_OUT1 to 0.7V, use
DAC_SetChannel1Data(DAC_Align_12b_R, 868);
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
DAC_DMACmd()
[..]
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
##### How to use this driver #####
===============================================================================
[..]
(+) DAC APB clock must be enabled to get write access to DAC
registers using
RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
(+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
(+) Configure the DAC channel using DAC_Init() function
(+) Enable the DAC channel using DAC_Cmd() function

*** 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
using DAC_SetChannel1Data() / DAC_SetChannel2Data() functions.
[..]
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...)
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
(#) 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
DAC_InitStructure.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 using DAC_WaveGeneration_Noise
(#) Triangle wave using DAC_WaveGeneration_Triangle
-@- Wave generation can be disabled using DAC_WaveGeneration_None
*** 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
VEF+ is the input voltage reference (refer to the device datasheet)
e.g. To set DAC_OUT1 to 0.7V, use
DAC_SetChannel1Data(DAC_Align_12b_R, 868);
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
DAC_DMACmd()
[..]
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
##### How to use this driver #####
===============================================================================
[..]
(+) DAC APB clock must be enabled to get write access to DAC
registers using
RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
(+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
(+) Configure the DAC channel using DAC_Init() function
(+) Enable the DAC channel using DAC_Cmd() function
