===============================================================================
I2C State Monitoring Functions
===============================================================================
This I2C driver provides three different ways for I2C state monitoring
depending on the application requirements and constraints:
1. Basic state monitoring (Using I2C_CheckEvent() function)
-----------------------------------------------------------
It compares the status registers (SR1 and SR2) content to a given event
(can be the combination of one or more flags).
It returns SUCCESS if the current status includes the given flags
and returns ERROR if one or more flags are missing in the current status.
- When to use
- This function is suitable for most applications as well as for startup
activity since the events are fully described in the product reference
manual (RM0038).
- It is also suitable for users who need to define their own events.
- Limitations
- If an error occurs (ie. error flags are set besides to the monitored
flags), the I2C_CheckEvent() function may return SUCCESS despite
the communication hold or corrupted real state.
In this case, it is advised to use error interrupts to monitor
the error events and handle them in the interrupt IRQ handler.
Note
For error management, it is advised to use the following functions:
- I2C_ITConfig() to configure and enable the error interrupts (I2C_IT_ERR).
- I2Cx_ER_IRQHandler() which is called when the error interrupt occurs.
Where x is the peripheral instance (I2C1, I2C2 ...)
- I2C_GetFlagStatus() or I2C_GetITStatus() to be called into the
I2Cx_ER_IRQHandler() function in order to determine which error occurred.
- I2C_ClearFlag() or I2C_ClearITPendingBit() and/or I2C_SoftwareResetCmd()
and/or I2C_GenerateStop() in order to clear the error flag and source
and return to correct communciation status.
2. Advanced state monitoring (Using the function I2C_GetLastEvent())
--------------------------------------------------------------------
Using the function I2C_GetLastEvent() which returns the image of both status
registers in a single word (uint32_t) (Status Register 2 value is shifted left
by 16 bits and concatenated to Status Register 1).
- When to use
- This function is suitable for the same applications above but it
allows to overcome the mentioned limitation of I2C_GetFlagStatus()
function.
- The returned value could be compared to events already defined in
the library (stm32l1xx_i2c.h) or to custom values defined by user.
This function is suitable when multiple flags are monitored at the
same time.
- At the opposite of I2C_CheckEvent() function, this function allows
user to choose when an event is accepted (when all events flags are
set and no other flags are set or just when the needed flags are set
like I2C_CheckEvent() function.
- Limitations
- User may need to define his own events.
- Same remark concerning the error management is applicable for this
function if user decides to check only regular communication flags
(and ignores error flags).
3. Flag-based state monitoring (Using the function I2C_GetFlagStatus())
-----------------------------------------------------------------------
Using the function I2C_GetFlagStatus() which simply returns the status of
one single flag (ie. I2C_FLAG_RXNE ...).
- When to use
- This function could be used for specific applications or in debug
phase.
- It is suitable when only one flag checking is needed (most I2C
events are monitored through multiple flags).
- Limitations:
- When calling this function, the Status register is accessed.
Some flags are cleared when the status register is accessed.
So checking the status of one Flag, may clear other ones.
- Function may need to be called twice or more in order to monitor
one single event.
For detailed description of Events, please refer to section I2C_Events in
stm32l1xx_i2c.h file.

* @brief This file provides firmware functions to manage the following
* functionalities of the AES peripheral:
* + Configuration
* + Read/Write operations
* + DMA transfers management
* + Interrupts and flags management
*
* @verbatim
===============================================================================
##### AES Peripheral features #####
===============================================================================
....[..]
(#) The Advanced Encryption Standard hardware accelerator (AES) can be used
to both encipher and decipher data using AES algorithm.
(#) The AES supports 4 operation modes:
(++) Encryption: It consumes 214 clock cycle when processing one 128-bit block
(++) Decryption: It consumes 214 clock cycle when processing one 128-bit block
(++) Key derivation for decryption: It consumes 80 clock cycle when processing one 128-bit block
(++) Key Derivation and decryption: It consumes 288 clock cycle when processing one 128-bit blobk
(#) Moreover 3 chaining modes are supported:
(++) Electronic codebook (ECB): Each plain text is encrypted/decrypted separately
(++) Cipher block chaining (CBC): Each block is XORed with the previous block
(++) Counter mode (CTR): A 128-bit counter is encrypted and then XORed with the
plain text to give the cipher text
(#) The AES peripheral supports data swapping: 1-bit, 8-bit, 16-bit and 32-bit.
(#) The AES peripheral supports write/read error handling with interrupt capability.
(#) Automatic data flow control with support of direct memory access (DMA) using
2 channels, one for incoming data (DMA2 Channel5), and one for outcoming data
(DMA2 Channel3).
##### How to use this driver #####
===============================================================================
[..]
(#) AES AHB clock must be enabled to get write access to AES registers
using RCC_AHBPeriphClockCmd(RCC_AHBPeriph_AES, ENABLE).
(#) Initialize the key using AES_KeyInit().
(#) Configure the AES operation mode using AES_Init().
(#) If required, enable interrupt source using AES_ITConfig() and
enable the AES interrupt vector using NVIC_Init().
(#) If required, when using the DMA mode.
(##) Configure the DMA using DMA_Init().
(##) Enable DMA requests using AES_DMAConfig().
(#) Enable the AES peripheral using AES_Cmd().

* @file stm32l1xx_comp.c
* @author MCD Application Team
* @version V1.1.1
* @date 05-March-2012
* @brief This file provides firmware functions to manage the following
* functionalities of the comparators (COMP1 and COMP2) peripheral:
* + Comparators configuration
* + Window mode control
* + Internal Reference Voltage (VREFINT) output
*
* @verbatim
===============================================================================
##### How to use this driver #####
===============================================================================
[..] The device integrates two analog comparators COMP1 and COMP2:
(+) COMP1 is a fixed threshold (VREFINT) that shares the non inverting
input with the ADC channels.
(+) COMP2 is a rail-to-rail comparator whose the inverting input can be
selected among: DAC_OUT1, DAC_OUT2, 1/4 VREFINT, 1/2 VERFINT, 3/4
VREFINT, VREFINT, PB3 and whose the output can be redirected to
embedded timers: TIM2, TIM3, TIM4, TIM10.
(+) The two comparators COMP1 and COMP2 can be combined in window mode.
-@-
(#@) Comparator APB clock must be enabled to get write access
to comparator register using
RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
(#@) COMP1 comparator and ADC can't be used at the same time since
they share the same ADC switch matrix (analog switches).
(#@) When an I/O is used as comparator input, the corresponding GPIO
registers should be configured in analog mode.
(#@) Comparators outputs (CMP1OUT and CMP2OUT) are not mapped on
GPIO pin. They are only internal.
To get the comparator output level, use COMP_GetOutputLevel().
(#@) COMP1 and COMP2 outputs are internally connected to EXTI Line 21
and EXTI Line 22 respectively.
Interrupts can be used by configuring the EXTI Line using the
EXTI peripheral driver.
(#@) After enabling the comparator (COMP1 or COMP2), user should wait
for start-up time (tSTART) to get right output levels.
Please refer to product datasheet for more information on tSTART.
(#@) Comparators cannot be used to exit the device from Sleep or Stop
mode when the internal reference voltage is switched off using
the PWR_UltraLowPowerCmd() function (ULP bit in the PWR_CR register).

* @file stm32l1xx_dac.c
* @author MCD Application Team
* @version V1.1.1
* @date 05-March-2012
* @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):
(#) DAC channel1 with DAC_OUT1 (PA4) as output.
(#) DAC channel2 with DAC_OUT2 (PA5) 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, TIM4, TIM6, TIM7 and TIM9
(DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...).
The timer TRGO event should be selected using TIM_SelectOutputTrigger()
(#) 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.
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+ = 3.3, 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 #####
===============================================================================
[..]
(+) 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()
(+) 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.

[..] This subsection provides functions allowing to configure the DMA Interrupts
sources and check or clear the flags or pending bits status.
The user should identify which mode will be used in his application to manage
the DMA controller events: Polling mode or Interrupt mode.
*** Polling Mode ***
====================
[..] 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.
(#) DMAy_FLAG_HTx : to indicate that a Half-Transfer Complete event occurred.
(#) DMAy_FLAG_TEx : to indicate that a Transfer Error occurred.
(#) DMAy_FLAG_GLx : to indicate that at least one of the events described
above occurred.
-@- Clearing DMAy_FLAG_GLx results in clearing all other pending flags of the
same channel (DMAy_FLAG_TCx, DMAy_FLAG_HTx and DMAy_FLAG_TEx).
[..]In this Mode it is advised to use the following functions:
(+) FlagStatus DMA_GetFlagStatus(uint32_t DMA_FLAG);
(+) void DMA_ClearFlag(uint32_t DMA_FLAG);
*** Interrupt Mode ***
======================
[..] Each DMA channel can be managed through 4 Interrupts:
(+) Interrupt Source
(##) DMA_IT_TC: specifies the interrupt source for the Transfer Complete
event.
(##) DMA_IT_HT : specifies the interrupt source for the Half-transfer Complete
event.
(##) DMA_IT_TE : specifies the interrupt source for the transfer errors event.
(##) DMA_IT_GL : to indicate that at least one of the interrupts described
above occurred.
-@@- Clearing DMA_IT_GL interrupt results in clearing all other interrupts of
the same channel (DMA_IT_TCx, DMA_IT_HT and DMA_IT_TE).

******************************************************************************
* @file stm32l1xx_iwdg.c
* @author MCD Application Team
* @version V1.1.1
* @date 05-March-2012
* @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 @37KHz (LSI): ~108us / ~28.3s
The IWDG timeout may vary due to LSI frequency dispersion. STM32L1xx
devices provide the capability to measure the LSI frequency (LSI clock
connected internally to TIM10 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 STM32L1xx Reference manual.
##### How to use this driver #####
==============================================================================
[..]
(#) 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.
(#) 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).
(#) Then the application program must reload the IWDG counter at regular
intervals during normal operation to prevent an MCU reset, using
IWDG_ReloadCounter() function.

*
* @verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..] The device integrates three independent rail-to-rail operational amplifiers
OPAMP1, OPAMP2 and OPAMP3:
(+) Internal connections to the ADC.
(+) Internal connections to the DAC.
(+) Internal connection to COMP1 (only OPAMP3).
(+) Internal connection for unity gain (voltage follower) configuration.
(+) Calibration capability.
(+) Selectable gain-bandwidth (2MHz in normal mode, 500KHz in low power mode).
[..]
(#) COMP AHB clock must be enabled to get write access
to OPAMP registers using
(#) RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE)
(#) Configure the corresponding GPIO to OPAMPx INP, OPAMPx_INN (if used)
and OPAMPx_OUT in analog mode.
(#) Configure (close/open) the OPAMP switches using OPAMP_SwitchCmd()
(#) Enable the OPAMP peripheral using OPAMP_Cmd()
-@- In order to use OPAMP outputs as ADC inputs, the opamps must be enabled
and the ADC must use the OPAMP output channel number:
(+@) OPAMP1 output is connected to ADC channel 3.
(+@) OPAMP2 output is connected to ADC channel 8.
(+@) OPAMP3 output is connected to ADC channel 13 (SW1 switch must be closed).

* @version V1.1.1
* @date 05-March-2012
* @brief This file provides firmware functions to manage the following
* functionalities of the SDIO peripheral:
* + Initialization
* + Interrupts and flags management
*
* @verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL
(PLLVCO) througth a fixed divider by 2.
Before to start working with SDIO peripheral make sure that the PLLVCO is
well configured to 96MHz.
The SDIO peripheral uses two clock signals:
(++) SDIO adapter clock (SDIOCLK = 48 MHz).
(++) APB2 bus clock (PCLK2).
PCLK2 and SDIO_CK clock frequencies must respect the following
condition: Frequenc(PCLK2) >= (3 / 8 x Frequency(SDIO_CK)).
(#) Enable peripheral clock using
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SDIO, ENABLE).
(#) According to the SDIO mode, enable the GPIO clocks using
RCC_AHBPeriphClockCmd() function.
The I/O can be one of the following configurations:
(++) 1-bit data length: SDIO_CMD, SDIO_CK and D0.
(++) 4-bit data length: SDIO_CMD, SDIO_CK and D[3:0].
(++) 8-bit data length: SDIO_CMD, SDIO_CK and D[7:0].
(#) Peripheral's alternate function:
(++) Connect the pin to the desired peripherals' Alternate
Function (AF) using GPIO_PinAFConfig() function.
(++) Configure the desired pin in alternate function by:
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.
(#) Program the Clock Edge, Clock Bypass, Clock Power Save, Bus Wide,
hardware, flow control and the Clock Divider using the SDIO_Init()
function.
(#) Enable the Power ON State using the SDIO_SetPowerState(SDIO_PowerState_ON)
function.
(#) Enable the clock using the SDIO_ClockCmd() function.
(#) Enable the NVIC and the corresponding interrupt using the function
SDIO_ITConfig() if you need to use interrupt mode.
(#) When using the DMA mode
(++) Configure the DMA using DMA_Init() function.
(++) Active the needed channel Request using SDIO_DMACmd() function.
(#) Enable the DMA using the DMA_Cmd() function, when using DMA mode.
(#) To control the CPSM (Command Path State Machine) and send commands to the
card use the SDIO_SendCommand(), SDIO_GetCommandResponse() and
SDIO_GetResponse() functions. First, user has to fill the command
structure (pointer to SDIO_CmdInitTypeDef) according to the selected
command to be sent. The parameters that should be filled are:
(++) Command Argument.
(++) Command Index.
(++) Command Response type.
(++) Command Wait.
(++) CPSM Status (Enable or Disable).
To check if the command is well received, read the SDIO_CMDRESP register
using the SDIO_GetCommandResponse(). The SDIO responses registers
(SDIO_RESP1 to SDIO_RESP2), use the SDIO_GetResponse() function.
(#) To control the DPSM (Data Path State Machine) and send/receive
data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
SDIO_ReadData(), SDIO_WriteData() and SDIO_GetFIFOCount() functions.
*** Read Operations ***
-----------------------
[..]
(#) First, user has to fill the data structure (pointer to
SDIO_DataInitTypeDef) according to the selected data type to be received.
The parameters that should be filled are:
(++) Data TimeOut.
(++) Data Length.
(++) Data Block size.
(++) Data Transfer direction: should be from card (To SDIO).
(++) Data Transfer mode.
(++) DPSM Status (Enable or Disable).
(#) Configure the SDIO resources to receive the data from the card
according to selected transfer mode (Refer to Step 8, 9 and 10).
(#) Send the selected Read command (refer to step 11).
(#) Use the SDIO flags/interrupts to check the transfer status.
*** Write Operations ***
------------------------

* @file stm32l1xx_wwdg.c
* @author MCD Application Team
* @version V1.1.1
* @date 05-March-2012
* @brief This file provides firmware functions to manage the following
* functionalities of the Window watchdog (WWDG) peripheral:
* + Prescaler, Refresh window and Counter configuration
* + WWDG activation
* + Interrupts and flags management
*
* @verbatim
*
==============================================================================
##### WWDG features #####
==============================================================================
[..] Once enabled the WWDG generates a system reset on expiry of a programmed
time period, unless the program refreshes the counter (downcounter)
before to reach 0x3F value (i.e. a reset is generated when the counter
value rolls over from 0x40 to 0x3F).
[..] An MCU reset is also generated if the counter value is refreshed
before the counter has reached the refresh window value. This
implies that the counter must be refreshed in a limited window.
[..] Once enabled the WWDG cannot be disabled except by a system reset.
[..] WWDGRST flag in RCC_CSR register can be used to inform when a WWDG
reset occurs.
[..] The WWDG counter input clock is derived from the APB clock divided
by a programmable prescaler.
[..] WWDG counter clock = PCLK1 / Prescaler.
[..] WWDG timeout = (WWDG counter clock) * (counter value).
[..] Min-max timeout value @32MHz (PCLK1): ~128us / ~65.6ms.
##### How to use this driver #####
==============================================================================
[..]
(#) Enable WWDG clock using RCC_APB1PeriphClockCmd(RCC_APB1Periph_WWDG, ENABLE)
function.
(#) Configure the WWDG prescaler using WWDG_SetPrescaler() function.
(#) Configure the WWDG refresh window using WWDG_SetWindowValue() function.
(#) Set the WWDG counter value and start it using WWDG_Enable() function.
When the WWDG is enabled the counter value should be configured to
a value greater than 0x40 to prevent generating an immediate reset.
(#) Optionally you can enable the Early wakeup interrupt which is
generated when the counter reach 0x40.
Once enabled this interrupt cannot be disabled except by a system reset.
(#) Then the application program must refresh the WWDG counter at regular
intervals during normal operation to prevent an MCU reset, using
WWDG_SetCounter() function. This operation must occur only when
the counter value is lower than the refresh window value,
programmed using WWDG_SetWindowValue().
