##### 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().

|
||||
* @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

|
||||
##### 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).

* + DAC channels configuration: trigger, output buffer, data format
|

* + DMA management
|

===============================================================================
|
||||
##### 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()

==============================================================================
|
||||
##### 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.

* @date 22-February-2013
|
||||
* @brief This file provides firmware functions to manage the following
|
||||
* functionalities of the EXTI peripheral:
|
||||
* + Initialization and Configuration
|
||||
* + Interrupts and flags management

==============================================================================
|

##### 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 the USB Device FS 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 Comparator channel acquisition 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()
|
||||
(#) Configure NVIC IRQ channel mapped to the EXTI line using NVIC_Init()
|
||||
[..]
|
||||
(@) SYSCFG APB clock must be enabled to get write access to SYSCFG_EXTICRx
|
||||
registers using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);

interface with SRAM, PSRAM, NOR or OneNAND memory connected to the
|
||||
NOR/SRAM Bank:
|
||||
(#) Enable the clock for the FSMC and associated GPIOs using the following
|
||||
functions:
|
||||
(++)RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);
|
||||
(++)RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOx, ENABLE);
|
||||
(#) FSMC pins configuration
|
||||
(++) Connect the involved FSMC pins to AF12 using the following function
|
||||
GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_FSMC);
|
||||
(++) Configure these FSMC pins in alternate function mode by calling the
|
||||
function GPIO_Init();
|
||||
(#) Declare a FSMC_NORSRAMInitTypeDef structure, for example:
|
||||
FSMC_NORSRAMInitTypeDef FSMC_NORSRAMInitStructure; and fill the
|
||||
FSMC_NORSRAMInitStructure variable with the allowed values of the
|
||||
structure member.
|
||||
(#) Initialize the NOR/SRAM Controller by calling the function
|
||||
FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);
|
||||
(#) Then enable the NOR/SRAM Bank, for example:
|
||||
FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM2, ENABLE);
|
||||
(#) At this stage you can read/write from/to the memory connected to the
|

NOR/SRAM Bank.

##### 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: Very Low, Low,
|
||||
Medium 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 PH0 and PH1, respectively, when the HSE
|
||||
oscillator is off. The HSE has priority over the GPIO function.

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.

##### 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.

===============================================================================
|
||||
##### LCD Clock #####
|
||||
===============================================================================
|
||||
[..] LCDCLK is the same as RTCCLK.
|
||||
[..] To configure the RTCCLK/LCDCLK, proceed as follows:
|
||||
(+) Enable the Power Controller (PWR) APB1 interface clock using the
|
||||
RCC_APB1PeriphClockCmd() function.
|
||||
(+) Enable access to RTC domain using the PWR_RTCAccessCmd() function.
|
||||
(+) Select the RTC clock source using the RCC_RTCCLKConfig() function.
|
||||
|
||||
[..] The frequency generator allows you to achieve various LCD frame rates
|
||||
starting from an LCD input clock frequency (LCDCLK) which can vary
|
||||
from 32 kHz up to 1 MHz.
|
||||
|
||||
##### LCD and low power modes #####
|
||||
===============================================================================
|
||||
[..] The LCD still active during STOP mode.
|
||||
|
||||
##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..]
|
||||
(#) Enable LCD clock using
|
||||
RCC_APB1PeriphClockCmd(RCC_APB1Periph_LCD, ENABLE) function.
|
||||
(#) Configure the LCD prescaler, divider, duty, bias and voltage source
|
||||
using LCD_Init() function.
|
||||
(#) Optionally you can enable/configure:
|
||||
(++) LCD High Drive using the LCD_HighDriveCmd() function.
|
||||
(++) LCD COM/SEG Mux using the LCD_MuxSegmentCmd() function.
|
||||
(++) LCD Pulse ON Duration using the LCD_PulseOnDurationConfig() function.
|
||||
(++) LCD Dead Time using the LCD_DeadTimeConfig() function
|
||||
(++) The LCD Blink mode and frequency using the LCD_BlinkConfig() function.
|
||||
(++) The LCD Contrast using the LCD_ContrastConfig() function.
|
||||
(#) Call the LCD_WaitForSynchro() function to wait for LCD_FCR register
|
||||
synchronization.
|
||||
(#) Call the LCD_Cmd() to enable the LCD controller.
|
||||
(#) Wait until the LCD Controller status is enabled and the step-up
|
||||
converter is ready using the LCD_GetFlagStatus() and
|
||||
LCD_FLAG_ENS and LCD_FLAG_RDY flags.
|
||||
(#) Write to the LCD RAM memory using the LCD_Write() function.
|
||||
(#) Request an update display using the LCD_UpdateDisplayRequest()
|
||||
function.
|
||||
(#) Wait until the update display is finished by checking the UDD
|
||||
flag status using the LCD_GetFlagStatus(LCD_FLAG_UDD).

##### LCD RAM memory write functions #####

|

[..] Using its double buffer memory the LCD controller ensures the coherency
|
||||
of the displayed information without having to use interrupts to control
|
||||
LCD_RAM modification.
|
||||
|
||||
[..] The application software can access the first buffer level (LCD_RAM) through
|
||||
the APB interface. Once it has modified the LCD_RAM, it sets the UDR flag
|
||||
in the LCD_SR register using the LCD_UpdateDisplayRequest() function.
|
||||
|
||||
[..] This UDR flag (update display request) requests the updated information
|
||||
to be moved into the second buffer level (LCD_DISPLAY).
|
||||
|
||||
[..] This operation is done synchronously with the frame (at the beginning of
|
||||
the next frame), until the update is completed, the LCD_RAM is write
|
||||
protected and the UDR flag stays high.
|
||||
|
||||
[..] Once the update is completed another flag (UDD - Update Display Done) is
|
||||
set and generates an interrupt if the UDDIE bit in the LCD_FCR register
|
||||
is set.
|
||||
|
||||
[..] The time it takes to update LCD_DISPLAY is, in the worst case, one odd
|
||||
and one even frame.
|
||||
|
||||
[..] The update will not occur (UDR = 1 and UDD = 0) until the display is
|
||||
enabled (LCDEN = 1).

* @date 22-February-2013
|
||||
* @brief This file provides firmware functions to manage the following
|
||||
* functionalities of the operational amplifiers (opamp) peripheral:
|
||||
* + Initialization and configuration
|
||||
* + Calibration management

##### 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).

(+) Stop mode: all clocks are stopped, regulator running, regulator in low power mode.
|
||||
(+) Standby mode: VCORE domain powered off.
|
||||
|
||||
*** Low power run mode (LP run) ***
|
||||
===================================
|
||||
[..]
|
||||
(+) Entry:
|
||||
(++) Decrease the system frequency.
|
||||
(++) The regulator is forced in low power mode using the PWR_EnterLowPowerRunMode()

(+) Exit:
|

(++) The regulator is forced in Main regulator mode sing the PWR_EnterLowPowerRunMode()
|
||||

(++) Increase the system frequency if needed.
|
||||
|
||||
*** Sleep mode ***
|
||||
==================
|
||||
[..]
|
||||
(+) Entry:
|
||||
(++) The Sleep mode is entered by using the PWR_EnterSleepMode(PWR_Regulator_ON,)
|
||||
function with regulator ON.
|

(+) Exit:
|
||||
(++) Any peripheral interrupt acknowledged by the nested vectored interrupt
|

||||
[..] In Stop mode, all clocks in the VCORE domain are stopped, the PLL, the MSI,
|
||||
the HSI and the HSE RC oscillators are disabled. Internal SRAM and register
|
||||
contents are preserved.
|
||||
The voltage regulator can be configured either in normal or low-power mode.
|
||||
To minimize the consumption In Stop mode, VREFINT, the BOR, PVD, and temperature
|
||||
sensor can be switched off before entering the Stop mode. They can be switched
|
||||
on again by software after exiting the Stop mode using the PWR_UltraLowPowerCmd()

|
||||
[..] The Standby mode allows to achieve the lowest power consumption. It is based
|
||||
on the Cortex-M3 deepsleep mode, with the voltage regulator disabled.
|
||||
The VCORE domain is consequently powered off. The PLL, the MSI, the HSI
|
||||
oscillator and the HSE oscillator are also switched off. SRAM and register
|
||||
contents are lost except for the RTC registers, RTC backup registers and
|
||||
Standby circuitry.

##### 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 ***

##### How to use this driver #####
|
||||
===============================================================================
|
||||
[..] This driver provides functions for:
|
||||
(#) Remapping the memory accessible in the code area using
|
||||
SYSCFG_MemoryRemapConfig().
|
||||
(#) Manage the EXTI lines connection to the GPIOs using
|
||||
SYSCFG_EXTILineConfig().
|
||||
(#) Routing of I/Os toward the input captures of timers (TIM2, TIM3 and TIM4).
|
||||
(#) Input routing of COMP1 and COMP2.
|
||||
(#) Routing of internal reference voltage VREFINT to PB0 and PB1.
|
||||
(#) The RI registers can be accessed only when the comparator
|
||||
APB interface clock is enabled.
|
||||
To enable comparator clock use:
|
||||
RCC_APB1PeriphClockCmd(RCC_APB1Periph_COMP, ENABLE).
|
||||
Following functions uses RI registers:
|
||||
(++) SYSCFG_RIDeInit()
|
||||
(++) SYSCFG_RITIMSelect()
|
||||
(++) SYSCFG_RITIMInputCaptureConfig()
|
||||
(++) SYSCFG_RIResistorConfig()
|
||||
(++) SYSCFG_RIChannelSpeedConfig()
|
||||
(++) SYSCFG_RIIOSwitchConfig()
|
||||
(++) SYSCFG_RISwitchControlModeCmd()
|
||||
(++) SYSCFG_RIHysteresisConfig()
|
||||
(#) The SYSCFG registers can be accessed only when the SYSCFG
|
||||
interface APB clock is enabled.
|
||||
To enable SYSCFG APB clock use:
|
||||
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
|
||||
Following functions uses SYSCFG registers:
|
||||
(++) SYSCFG_DeInit()
|
||||
(++) SYSCFG_MemoryRemapConfig()
|
||||
(++) SYSCFG_GetBootMode()
|
||||
(++) SYSCFG_USBPuCmd()
|

* @brief This file provides firmware functions to manage the following

|

* + Prescaler, Refresh window and Counter configuration

|
||||
##### 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().

|
||||
* @date 8-January-2014
|
||||
* @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File.
|
||||
* This file contains the system clock configuration for STM32L1xx Ultra
|
||||
* Low power devices, and is generated by the clock configuration
|
||||
* tool STM32L1xx_Clock_Configuration_V1.2.0.xls
|
||||
*
|
||||
* 1. This file provides two functions and one global variable to be called from
|
||||
* user application:
|
||||
* - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
|
||||
* and Divider factors, AHB/APBx prescalers and Flash settings),
|
||||
* depending on the configuration made in the clock xls tool.
|
||||
* This function is called at startup just after reset and
|
||||
* before branch to main program. This call is made inside
|
||||
* the "startup_stm32l1xx_xx.s" file.
|
||||
*
|
||||
* - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
|
||||
* by the user application to setup the SysTick
|
||||
* timer or configure other parameters.
|
||||
*
|
||||
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
|
||||
* be called whenever the core clock is changed
|
||||
* during program execution.
|
||||
*
|
||||
* 2. After each device reset the MSI (2.1 MHz Range) is used as system clock source.
|
||||
* Then SystemInit() function is called, in "startup_stm32l1xx_xx.s" file, to
|
||||
* configure the system clock before to branch to main program.
|
||||
*
|
||||
* 3. If the system clock source selected by user fails to startup, the SystemInit()
|
||||
* function will do nothing and MSI still used as system clock source. User can
|
||||
* add some code to deal with this issue inside the SetSysClock() function.
|
||||
*
|
||||
* 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
|
||||
* in "stm32l1xx.h" file. When HSE is used as system clock source, directly or
|
||||
* through PLL, and you are using different crystal you have to adapt the HSE
|
||||
* value to your own configuration.
|
||||
*
|
||||
* 5. This file configures the system clock as follows:
