* @version V1.1.0
* @date 27-February-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 #####
===============================================================================
[..] The device integrates two 12-bit Digital Analog Converters that can
be used independently or simultaneously (dual mode):
(#) DAC1 integrates two DAC channels:
(++) DAC1 channel 1 with DAC1_OUT1 as output
(++) DAC1 channel 2 with DAC1_OUT2 as output
(++) The two channels can be used independently or simultaneously (dual mode)
(#) DAC2 integrates only one channel DAC2 channel 1 with DAC2_OUT1 as output
[..] 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.
[..] 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, TIM8/TIM3, TIM4, TIM6, TIM7, and TIM15
(DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
(++) To trigger DAC conversions by TIM3 instead of TIM8 follow
this sequence:
(+++) Enable SYSCFG APB clock by calling
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
(+++) Select DAC_Trigger_T3_TRGO when calling DAC_Init()
(+++) Remap the DAC trigger from TIM8 to TIM3 by calling
SYSCFG_TriggerRemapConfig(SYSCFG_TriggerRemap_DACTIM3, ENABLE)
(#) Software using DAC_Trigger_Software
[..] 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.
[..] 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
[..] 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
[..] 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 DAC_SetChannel1Data(DAC_Align_12b_R, 868);
Assuming that VREF+ = 3.3, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
[..] 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 is mapped on DMA1 channel3 which must be already
configured
(+) DAC channel2 is mapped on DMA1 channel4 which must be already
configured
##### How to use this driver #####
===============================================================================
[..]
(+) Enable DAC APB1 clock to get write access to DAC registers
using RCC_APB1PeriphClockCmd(RCC_APB1Periph_DAC, ENABLE)
(+) Configure DACx_OUTy (DAC1_OUT1: PA4, DAC1_OUT2: PA5, DAC2_OUT1: PA6)
in analog mode.
(+) Configure the DAC channel using DAC_Init()
(+) Enable the DAC channel using DAC_Cmd()

* @brief This file provides firmware functions to manage the following
* functionalities of the Direct Memory Access controller (DMA):
* + Initialization and Configuration
* + Data Counter
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..]
(#) Enable The DMA controller clock using
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE) function for DMA1 or
using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE) function for DMA2.
(#) Enable and configure the peripheral to be connected to the DMA channel
(except for internal SRAM / FLASH memories: no initialization is necessary).
(#) For a given Channel, program the Source and Destination addresses,
the transfer Direction, the Buffer Size, the Peripheral and Memory
Incrementation mode and Data Size, the Circular or Normal mode,
the channel transfer Priority and the Memory-to-Memory transfer
mode (if needed) using the DMA_Init() function.
(#) Enable the NVIC and the corresponding interrupt(s) using the function
DMA_ITConfig() if you need to use DMA interrupts.
(#) Enable the DMA channel using the DMA_Cmd() function.
(#) Activate the needed channel Request using PPP_DMACmd() function for
any PPP peripheral except internal SRAM and FLASH (ie. SPI, USART ...)
The function allowing this operation is provided in each PPP peripheral
driver (ie. SPI_DMACmd for SPI peripheral).
(#) Optionally, you can configure the number of data to be transferred
when the channel is disabled (ie. after each Transfer Complete event
or when a Transfer Error occurs) using the function DMA_SetCurrDataCounter().
And you can get the number of remaining data to be transferred using
the function DMA_GetCurrDataCounter() at run time (when the DMA channel is
enabled and running).
(#) To control DMA events you can use one of the following two methods:
(##) Check on DMA channel flags using the function DMA_GetFlagStatus().
(##) Use DMA interrupts through the function DMA_ITConfig() at initialization
phase and DMA_GetITStatus() function into interrupt routines in
communication phase.
After checking on a flag you should clear it using DMA_ClearFlag()
function. And after checking on an interrupt event you should
clear it using DMA_ClearITPendingBit() function.

====================
[..] Each DMA channel can be managed through 4 event Flags (y : DMA Controller
number, x : DMA channel number):
(#) DMAy_FLAG_TCx : to indicate that a Transfer Complete event occurred.

* @version V1.1.0
* @date 27-February-2014
* @brief This file provides firmware functions to manage the following
* functionalities of the EXTI peripheral:
* + Initialization and Configuration
* + Interrupts and flags management
*
@verbatim
===============================================================================
##### EXTI features #####
===============================================================================
[..] External interrupt/event lines are mapped as following:
(#) All available GPIO pins are connected to the 16 external
interrupt/event lines from EXTI0 to EXTI15.
(#) EXTI line 16 is connected to the PVD output
(#) EXTI line 17 is connected to the RTC Alarm event
(#) EXTI line 18 is connected to USB Device wakeup event
(#) EXTI line 19 is connected to the RTC Tamper and TimeStamp events
(#) EXTI line 20 is connected to the RTC wakeup event
(#) EXTI line 21 is connected to the Comparator 1 wakeup event
(#) EXTI line 22 is connected to the Comparator 2 wakeup event
(#) EXTI line 23 is connected to the I2C1 wakeup event
(#) EXTI line 24 is connected to the I2C2 wakeup event
(#) EXTI line 25 is connected to the USART1 wakeup event
(#) EXTI line 26 is connected to the USART2 wakeup event
(#) EXTI line 27 is reserved
(#) EXTI line 28 is connected to the USART3 wakeup event
(#) EXTI line 29 is connected to the Comparator 3 event
(#) EXTI line 30 is connected to the Comparator 4 event
(#) EXTI line 31 is connected to the Comparator 5 event
(#) EXTI line 32 is connected to the Comparator 6 event
(#) EXTI line 33 is connected to the Comparator 7 event
(#) EXTI line 34 is connected for thr UART4 wakeup event
(#) EXTI line 35 is connected for the UART5 wakeup event
##### How to use this driver #####
===============================================================================
[..] In order to use an I/O pin as an external interrupt source,
follow steps below:
(#) Configure the I/O in input mode using GPIO_Init().
(#) Select the input source pin for the EXTI line using
SYSCFG_EXTILineConfig().
(#) Select the mode(interrupt, event) and configure the trigger
selection (Rising, falling or both) using EXTI_Init(). For the
internal interrupt, the trigger selection is not needed
(the active edge is always the rising one).
(#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init().
(#) Optionally, you can generate a software interrupt using the function
EXTI_GenerateSWInterrupt().
[..]
(@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

##### How to use this driver #####
===============================================================================
[..]
(#) Enable the GPIO AHB clock using RCC_AHBPeriphClockCmd()
(#) Configure the GPIO pin(s) using GPIO_Init()
Four possible configuration are available for each pin:
(++) Input: Floating, Pull-up, Pull-down.
(++) Output: Push-Pull (Pull-up, Pull-down or no Pull),
Open Drain (Pull-up, Pull-down or no Pull).
In output mode, the speed is configurable: Low, Medium, Fast or High.
(++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull),
Open Drain (Pull-up, Pull-down or no Pull).
(++) Analog: required mode when a pin is to be used as ADC channel,
DAC output or comparator input.
(#) Peripherals alternate function:
(++) For ADC, DAC and comparators, configure the desired pin in
analog mode using GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN
(++) For other peripherals (TIM, USART...):
(+++) Connect the pin to the desired peripherals' Alternate
Function (AF) using GPIO_PinAFConfig() function.
(+++) Configure the desired pin in alternate function mode using
GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
(+++) Select the type, pull-up/pull-down and output speed via
GPIO_PuPd, GPIO_OType and GPIO_Speed members.
(+++) Call GPIO_Init() function.
(#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
(#) To set/reset the level of a pin configured in output mode use
GPIO_SetBits()/GPIO_ResetBits()
(#) During and just after reset, the alternate functions are not active
and the GPIO pins are configured in input floating mode (except JTAG pins).
(#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as
general-purpose (PC14 and PC15, respectively) when the LSE
oscillator is off. The LSE has priority over the GPIO function.
(#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as general-purpose
(PF0 and PF1 respectively) when the HSE oscillator is off. The HSE has
the priority over the GPIO function.

* @file stm32f30x_iwdg.c
* @author MCD Application Team
* @version V1.1.0
* @date 27-February-2014
* @brief This file provides firmware functions to manage the following
* functionalities of the Independent watchdog (IWDG) peripheral:
* + Prescaler and Counter configuration
* + IWDG activation
* + Flag management
*
@verbatim
===============================================================================
##### IWDG features #####
===============================================================================
[..] The IWDG can be started by either software or hardware (configurable
through option byte).
[..] The IWDG is clocked by its own dedicated low-speed clock (LSI) and
thus stays active even if the main clock fails.
Once the IWDG is started, the LSI is forced ON and cannot be disabled
(LSI cannot be disabled too), and the counter starts counting down from
the reset value of 0xFFF. When it reaches the end of count value (0x000)
a system reset is generated.
The IWDG counter should be reloaded at regular intervals to prevent
an MCU reset.
[..] The IWDG is implemented in the VDD voltage domain that is still functional
in STOP and STANDBY mode (IWDG reset can wake-up from STANDBY).
[..] IWDGRST flag in RCC_CSR register can be used to inform when a IWDG
reset occurs.
[..] Min-max timeout value @41KHz (LSI): ~0.1ms / ~25.5s
The IWDG timeout may vary due to LSI frequency dispersion. STM32F30x
devices provide the capability to measure the LSI frequency (LSI clock
connected internally to TIM16 CH1 input capture). The measured value
can be used to have an IWDG timeout with an acceptable accuracy.
For more information, please refer to the STM32F30x Reference manual.
##### How to use this driver #####
===============================================================================
[..] This driver allows to use IWDG peripheral with either window option enabled
or disabled. To do so follow one of the two procedures below.
(#) Window option is enabled:
(++) Start the IWDG using IWDG_Enable() function, when the IWDG is used
in software mode (no need to enable the LSI, it will be enabled
by hardware).
(++) Enable write access to IWDG_PR and IWDG_RLR registers using
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function.
(++) Configure the IWDG prescaler using IWDG_SetPrescaler() function.
(++) Configure the IWDG counter value using IWDG_SetReload() function.
This value will be loaded in the IWDG counter each time the counter
is reloaded, then the IWDG will start counting down from this value.
(++) Wait for the IWDG registers to be updated using IWDG_GetFlagStatus() function.
(++) Configure the IWDG refresh window using IWDG_SetWindowValue() function.
(#) Window option is disabled:
(++) Enable write access to IWDG_PR and IWDG_RLR registers using
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable) function.
(++) Configure the IWDG prescaler using IWDG_SetPrescaler() function.
(++) Configure the IWDG counter value using IWDG_SetReload() function.
This value will be loaded in the IWDG counter each time the counter
is reloaded, then the IWDG will start counting down from this value.
(++) Wait for the IWDG registers to be updated using IWDG_GetFlagStatus() function.
(++) reload the IWDG counter at regular intervals during normal operation
to prevent an MCU reset, using IWDG_ReloadCounter() function.
(++) Start the IWDG using IWDG_Enable() function, when the IWDG is used
in software mode (no need to enable the LSI, it will be enabled
by hardware).

(#) Configure the NVIC Priority Grouping using NVIC_PriorityGroupConfig()
function according to the following table.
The table below gives the allowed values of the pre-emption priority

performed by NVIC_PriorityGroupConfig function.
(#) Enable and Configure the priority of the selected IRQ Channels.
[..]
(@) When the NVIC_PriorityGroup_0 is selected, it will no any nested interrupt,
the IRQ priority will be managed only by subpriority.
The sub-priority is only used to sort pending exception priorities,
and does not affect active exceptions.
(@) Lower priority values gives higher priority.
(@) Priority Order:
(#@) Lowest Preemption priority.
(#@) Lowest Subpriority.
(#@) Lowest hardware priority (IRQn position).

@verbatim
==============================================================================
##### OPAMP Peripheral Features #####
==============================================================================
[..]
The device integrates 4 operational amplifiers OPAMP1, OPAMP2, OPAMP3 and OPAMP4:
(+) The OPAMPs non inverting input can be selected among the list shown by
table below.
(+) The OPAMPs inverting input can be selected among the list shown by
table below.
(+) The OPAMPs outputs can be internally connected to the inverting input
(follower mode)
(+) The OPAMPs outputs can be internally connected to resistor feedback
output (Programmable Gain Amplifier mode)
(+) The OPAMPs outputs can be internally connected to ADC
(+) The OPAMPs can be calibrated to compensate the offset compensation
(+) Timer-controlled Mux for automatic switch of inverting and
non-inverting input
OPAMPs inverting/non-inverting inputs:
+--------------------------------------------------------------+
| | | OPAMP1 | OPAMP2 | OPAMP3 | OPAMP4 |
|-----------------|--------|--------|--------|--------|--------|

##### How to use this driver #####
==============================================================================
[..]
This driver provides functions to configure and program the OPAMP
of all STM32F30x devices.
To use the OPAMP, perform the following steps:
(#) Enable the SYSCFG APB clock to get write access to OPAMP
register using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
(#) Configure the OPAMP input in analog mode using GPIO_Init()
(#) Configure the OPAMP using OPAMP_Init() function:
(++) Select the inverting input
(++) Select the non-inverting inverting input
(#) Enable the OPAMP using OPAMP_Cmd() function
