+  *              - To use or not the peripheral’s drivers in application code(i.e. 
+  *                code will be based on direct access to peripheral’s registers 
+  *                rather than drivers API), this option is controlled by

+  *            (i.e. HAL_PPP_MspInit() will not be executed).
+  *          - When there is a need to reconfigure the low level hardware: instead of calling
+  *            HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
+  *            In this later function, when the Handle's "State" field is set to 0, it will execute the function

+  *           + Initialization and de-initialization functions
+  *           + Peripheral Control functions

+                        ##### How to use this driver #####
+  ==============================================================================
+
+    [..]  
+    *** How to configure Interrupts using CORTEX HAL driver ***
+    ===========================================================
+    [..]     
+    This section provides functions allowing to configure the NVIC interrupts (IRQ).
+    The Cortex-M3 exceptions are managed by CMSIS functions.
+   
+    (#) Configure the NVIC Priority Grouping using HAL_NVIC_SetPriorityGrouping()
+        function according to the following table.
+    (#) Configure the priority of the selected IRQ Channels using HAL_NVIC_SetPriority(). 
+    (#) Enable the selected IRQ Channels using HAL_NVIC_EnableIRQ().
+    (#) please refer to programming manual for details in how to configure priority. 
+      
+     -@- When the NVIC_PRIORITYGROUP_0 is selected, IRQ preemption is no more possible. 
+         The pending IRQ priority will be managed only by the sub priority.
+   
+     -@- IRQ priority order (sorted by highest to lowest priority):
+        (+@) Lowest preemption priority
+        (+@) Lowest sub priority
+        (+@) Lowest hardware priority (IRQ number)
+ 
+    [..]  
+    *** How to configure Systick using CORTEX HAL driver ***
+    ========================================================
+    [..]
+    Setup SysTick Timer for time base.
+           
+   (+) The HAL_SYSTICK_Config()function calls the SysTick_Config() function which
+       is a CMSIS function that:
+        (++) Configures the SysTick Reload register with value passed as function parameter.
+        (++) Configures the SysTick IRQ priority to the lowest value 0x0F.
+        (++) Resets the SysTick Counter register.
+        (++) Configures the SysTick Counter clock source to be Core Clock Source (HCLK).
+        (++) Enables the SysTick Interrupt.
+        (++) Starts the SysTick Counter.
+    
+   (+) You can change the SysTick Clock source to be HCLK_Div8 by calling the macro
+       __HAL_CORTEX_SYSTICKCLK_CONFIG(SYSTICK_CLKSOURCE_HCLK_DIV8) just after the
+       HAL_SYSTICK_Config() function call. The __HAL_CORTEX_SYSTICKCLK_CONFIG() macro is defined
+       inside the stm32f1xx_hal_cortex.h file.
+
+   (+) You can change the SysTick IRQ priority by calling the
+       HAL_NVIC_SetPriority(SysTick_IRQn,...) function just after the HAL_SYSTICK_Config() function 
+       call. The HAL_NVIC_SetPriority() call the NVIC_SetPriority() function which is a CMSIS function.
+
+   (+) To adjust the SysTick time base, use the following formula:
+                            
+       Reload Value = SysTick Counter Clock (Hz) x  Desired Time base (s)
+       (++) Reload Value is the parameter to be passed for HAL_SYSTICK_Config() function
+       (++) Reload Value should not exceed 0xFFFFFF

+  * @brief   DMA HAL module driver.
+  *         This file provides firmware functions to manage the following
+  *         functionalities of the Direct Memory Access (DMA) peripheral:
+  *           + Initialization and de-initialization functions
+  *           + IO operation functions
+  *           + Peripheral State and errors functions
+  @verbatim
+  ==============================================================================
+                        ##### How to use this driver #####
+  ==============================================================================
+  [..]
+   (#) Enable and configure the peripheral to be connected to the DMA Channel
+       (except for internal SRAM / FLASH memories: no initialization is 
+       necessary). Please refer to the Reference manual for connection between peripherals
+       and DMA requests.
+
+   (#) For a given Channel, program the required configuration through the following parameters:
+       Channel request, Transfer Direction, Source and Destination data formats,
+       Circular or Normal mode, Channel Priority level, Source and Destination Increment mode
+       using HAL_DMA_Init() function.
+
+   (#) Use HAL_DMA_GetState() function to return the DMA state and HAL_DMA_GetError() in case of error 
+       detection.
+                    
+   (#) Use HAL_DMA_Abort() function to abort the current transfer
+                   
+     -@-   In Memory-to-Memory transfer mode, Circular mode is not allowed.
+     *** Polling mode IO operation ***
+     =================================
+    [..]
+          (+) Use HAL_DMA_Start() to start DMA transfer after the configuration of Source
+              address and destination address and the Length of data to be transferred
+          (+) Use HAL_DMA_PollForTransfer() to poll for the end of current transfer, in this
+              case a fixed Timeout can be configured by User depending from his application.
+
+     *** Interrupt mode IO operation ***
+     ===================================
+    [..]
+          (+) Configure the DMA interrupt priority using HAL_NVIC_SetPriority()
+          (+) Enable the DMA IRQ handler using HAL_NVIC_EnableIRQ()
+          (+) Use HAL_DMA_Start_IT() to start DMA transfer after the configuration of
+              Source address and destination address and the Length of data to be transferred.
+              In this case the DMA interrupt is configured
+          (+) Use HAL_DMA_IRQHandler() called under DMA_IRQHandler() Interrupt subroutine
+          (+) At the end of data transfer HAL_DMA_IRQHandler() function is executed and user can
+              add his own function by customization of function pointer XferCpltCallback and
+              XferErrorCallback (i.e. a member of DMA handle structure).
+
+     *** DMA HAL driver macros list ***
+     ============================================= 
+      [..]
+       Below the list of most used macros in DMA HAL driver.
+
+       (+) __HAL_DMA_ENABLE: Enable the specified DMA Channel.
+       (+) __HAL_DMA_DISABLE: Disable the specified DMA Channel.
+       (+) __HAL_DMA_GET_FLAG: Get the DMA Channel pending flags.
+       (+) __HAL_DMA_CLEAR_FLAG: Clear the DMA Channel pending flags.
+       (+) __HAL_DMA_ENABLE_IT: Enable the specified DMA Channel interrupts.
+       (+) __HAL_DMA_DISABLE_IT: Disable the specified DMA Channel interrupts.
+       (+) __HAL_DMA_GET_IT_SOURCE: Check whether the specified DMA Channel interrupt has occurred or not. 
+
+     [..] 
+      (@) You can refer to the DMA HAL driver header file for more useful macros

+  [..]
+    (+) Each Exti line can be configured within this driver.
+
+    (+) Exti line can be configured in 3 different modes
+        (++) Interrupt
+        (++) Event
+        (++) Both of them
+
+    (+) Configurable Exti lines can be configured with 3 different triggers
+        (++) Rising
+        (++) Falling
+        (++) Both of them
+
+    (+) When set in interrupt mode, configurable Exti lines have two different
+        interrupts pending registers which allow to distinguish which transition
+        occurs:
+        (++) Rising edge pending interrupt
+        (++) Falling
+
+    (+) Exti lines 0 to 15 are linked to gpio pin number 0 to 15. Gpio port can
+        be selected through multiplexer.
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+
+    (#) Configure the EXTI line using HAL_EXTI_SetConfigLine().
+        (++) Choose the interrupt line number by setting "Line" member from
+             EXTI_ConfigTypeDef structure.
+        (++) Configure the interrupt and/or event mode using "Mode" member from
+             EXTI_ConfigTypeDef structure.
+        (++) For configurable lines, configure rising and/or falling trigger
+             "Trigger" member from EXTI_ConfigTypeDef structure.
+        (++) For Exti lines linked to gpio, choose gpio port using "GPIOSel"
+             member from GPIO_InitTypeDef structure.
+
+    (#) Get current Exti configuration of a dedicated line using
+        HAL_EXTI_GetConfigLine().
+        (++) Provide exiting handle as parameter.
+        (++) Provide pointer on EXTI_ConfigTypeDef structure as second parameter.
+
+    (#) Clear Exti configuration of a dedicated line using HAL_EXTI_GetConfigLine().
+        (++) Provide exiting handle as parameter.
+
+    (#) Register callback to treat Exti interrupts using HAL_EXTI_RegisterCallback().
+        (++) Provide exiting handle as first parameter.
+        (++) Provide which callback will be registered using one value from
+             EXTI_CallbackIDTypeDef.
+        (++) Provide callback function pointer.
+
+    (#) Get interrupt pending bit using HAL_EXTI_GetPending().
+
+    (#) Clear interrupt pending bit using HAL_EXTI_GetPending().
+
+    (#) Generate software interrupt using HAL_EXTI_GenerateSWI().

+  * @brief   FLASH HAL module driver.
+  *          This file provides firmware functions to manage the following 
+  *          functionalities of the internal FLASH memory:
+  *           + Program operations functions
+  *           + Memory Control functions 
+  *           + Peripheral State functions
+  *         
+  @verbatim
+  ==============================================================================
+                        ##### FLASH peripheral features #####
+  ==============================================================================
+  [..] The Flash memory interface manages CPU AHB I-Code and D-Code accesses 
+       to the Flash memory. It implements the erase and program Flash memory operations 
+       and the read and write protection mechanisms.
+
+  [..] The Flash memory interface accelerates code execution with a system of instruction
+      prefetch. 
+
+  [..] The FLASH main features are:
+      (+) Flash memory read operations
+      (+) Flash memory program/erase operations
+      (+) Read / write protections
+      (+) Prefetch on I-Code
+      (+) Option Bytes programming
+
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]                             
+      This driver provides functions and macros to configure and program the FLASH 
+      memory of all STM32F1xx devices.
+    
+      (#) FLASH Memory I/O Programming functions: this group includes all needed
+          functions to erase and program the main memory:
+        (++) Lock and Unlock the FLASH interface
+        (++) Erase function: Erase page, erase all pages
+        (++) Program functions: half word, word and doubleword
+      (#) FLASH Option Bytes Programming functions: this group includes all needed
+          functions to manage the Option Bytes:
+        (++) Lock and Unlock the Option Bytes
+        (++) Set/Reset the write protection
+        (++) Set the Read protection Level
+        (++) Program the user Option Bytes
+        (++) Launch the Option Bytes loader
+        (++) Erase Option Bytes
+        (++) Program the data Option Bytes
+        (++) Get the Write protection.
+        (++) Get the user option bytes.
+    
+      (#) Interrupts and flags management functions : this group 
+          includes all needed functions to:
+        (++) Handle FLASH interrupts
+        (++) Wait for last FLASH operation according to its status
+        (++) Get error flag status
+
+  [..] In addition to these function, this driver includes a set of macros allowing
+       to handle the following operations:
+      
+      (+) Set/Get the latency
+      (+) Enable/Disable the prefetch buffer
+      (+) Enable/Disable the half cycle access
+      (+) Enable/Disable the FLASH interrupts
+      (+) Monitor the FLASH flags status

+  * @brief   GPIO HAL module driver.
+  *          This file provides firmware functions to manage the following
+  *          functionalities of the General Purpose Input/Output (GPIO) peripheral:
+  *           + Initialization and de-initialization functions
+  *           + IO operation functions
+  *
+  @verbatim
+  ==============================================================================
+                    ##### GPIO Peripheral features #####
+  ==============================================================================
+  [..]
+  Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each
+  port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software
+  in several modes:
+  (+) Input mode
+  (+) Analog mode
+  (+) Output mode
+  (+) Alternate function mode
+  (+) External interrupt/event lines
+
+  [..]
+  During and just after reset, the alternate functions and external interrupt
+  lines are not active and the I/O ports are configured in input floating mode.
+
+  [..]
+  All GPIO pins have weak internal pull-up and pull-down resistors, which can be
+  activated or not.
+
+  [..]
+  In Output or Alternate mode, each IO can be configured on open-drain or push-pull
+  type and the IO speed can be selected depending on the VDD value.
+
+  [..]
+  All ports have external interrupt/event capability. To use external interrupt
+  lines, the port must be configured in input mode. All available GPIO pins are
+  connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
+
+  [..]
+  The external interrupt/event controller consists of up to 20 edge detectors in connectivity
+  line devices, or 19 edge detectors in other devices for generating event/interrupt requests.
+  Each input line can be independently configured to select the type (event or interrupt) and
+  the corresponding trigger event (rising or falling or both). Each line can also masked
+  independently. A pending register maintains the status line of the interrupt requests
+
+                     ##### How to use this driver #####
+  ==============================================================================
+ [..]
+   (#) Enable the GPIO APB2 clock using the following function : __HAL_RCC_GPIOx_CLK_ENABLE().
+
+   (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
+       (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
+       (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
+            structure.
+       (++) In case of Output or alternate function mode selection: the speed is
+            configured through "Speed" member from GPIO_InitTypeDef structure
+       (++) Analog mode is required when a pin is to be used as ADC channel
+            or DAC output.
+       (++) In case of external interrupt/event selection the "Mode" member from
+            GPIO_InitTypeDef structure select the type (interrupt or event) and
+            the corresponding trigger event (rising or falling or both).
+
+   (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
+       mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
+       HAL_NVIC_EnableIRQ().
+
+   (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
+
+   (#) To set/reset the level of a pin configured in output mode use
+       HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
+
+   (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
+
+   (#) 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 PD0 and PD1, respectively, when the HSE oscillator is off.
+       The HSE has priority over the GPIO function.

+  @verbatim
+  ==============================================================================
+                    ##### IWDG Generic features #####
+  ==============================================================================
+  [..]
+    (+) The IWDG can be started by either software or hardware (configurable
+        through option byte).
+
+    (+) The IWDG is clocked by 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 both can not be
+        disabled. The counter starts counting down from the reset value (0xFFF).
+        When it reaches the end of count value (0x000) a reset signal is
+        generated (IWDG reset).
+
+    (+) Whenever the key value 0x0000 AAAA is written in the IWDG_KR register,
+        the IWDG_RLR value is reloaded in the counter and the watchdog reset is
+        prevented.
+
+    (+) 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 an IWDG
+        reset occurs.
+
+    (+) Debug mode : When the microcontroller enters debug mode (core halted),
+        the IWDG counter either continues to work normally or stops, depending
+        on DBG_IWDG_STOP configuration bit in DBG module, accessible through
+        __HAL_DBGMCU_FREEZE_IWDG() and __HAL_DBGMCU_UNFREEZE_IWDG() macros
+
+    [..] Min-max timeout value @32KHz (LSI): ~125us / ~32.7s
+         The IWDG timeout may vary due to LSI frequency dispersion. STM32F1xx
+         devices provide the capability to measure the LSI frequency (LSI clock
+         connected internally to TIM5 CH4 input capture). The measured value
+         can be used to have an IWDG timeout with an acceptable accuracy.
+
+                     ##### How to use this driver #####
+  ==============================================================================
+  [..]
+    (#) Use IWDG using HAL_IWDG_Init() function to :
+      (++) Enable instance by writing Start keyword in IWDG_KEY register. LSI
+           clock is forced ON and IWDG counter starts downcounting.
+      (++) Enable write access to configuration register: IWDG_PR & IWDG_RLR.
+      (++) Configure the IWDG prescaler and counter reload value. This reload
+           value will be loaded in the IWDG counter each time the watchdog is
+           reloaded, then the IWDG will start counting down from this value.
+      (++) wait for status flags to be reset"
+
+    (#) Then the application program must refresh the IWDG counter at regular
+        intervals during normal operation to prevent an MCU reset, using
+        HAL_IWDG_Refresh() function.
+
+     *** IWDG HAL driver macros list ***
+     ====================================
+     [..]
+       Below the list of most used macros in IWDG HAL driver:
+      (+) __HAL_IWDG_START: Enable the IWDG peripheral
+      (+) __HAL_IWDG_RELOAD_COUNTER: Reloads IWDG counter with value defined in
+          the reload register

+ ===============================================================================
+     
+    *** PVD configuration ***
+    =========================
+    [..]
+      (+) The PVD is used to monitor the VDD power supply by comparing it to a
+          threshold selected by the PVD Level (PLS[2:0] bits in the PWR_CR).
+
+      (+) A PVDO flag is available to indicate if VDD/VDDA is higher or lower
+          than the PVD threshold. This event is internally connected to the EXTI
+          line16 and can generate an interrupt if enabled. This is done through
+          __HAL_PVD_EXTI_ENABLE_IT() macro.
+      (+) The PVD is stopped in Standby mode.
+
+    *** WakeUp pin configuration ***
+    ================================
+    [..]
+      (+) WakeUp pin is used to wake up the system from Standby mode. This pin is
+          forced in input pull-down configuration and is active on rising edges.
+      (+) There is one WakeUp pin:
+          WakeUp Pin 1 on PA.00.
+
+    [..]
+
+    *** Low Power modes configuration ***
+    =====================================
+     [..]
+      The device features 3 low-power modes:
+      (+) Sleep mode: CPU clock off, all peripherals including Cortex-M3 core peripherals like 
+                      NVIC, SysTick, etc. are kept running
+      (+) Stop mode: All clocks are stopped
+      (+) Standby mode: 1.8V domain powered off
+  
+  
+   *** Sleep mode ***
+   ==================
+    [..]
+      (+) Entry:
+          The Sleep mode is entered by using the HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFx)
+              functions with
+          (++) PWR_SLEEPENTRY_WFI: enter SLEEP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFE: enter SLEEP mode with WFE instruction
+     
+      (+) Exit:
+        (++) WFI entry mode, Any peripheral interrupt acknowledged by the nested vectored interrupt
+             controller (NVIC) can wake up the device from Sleep mode.
+        (++) WFE entry mode, Any wakeup event can wake up the device from Sleep mode.
+           (+++) Any peripheral interrupt w/o NVIC configuration & SEVONPEND bit set in the Cortex (HAL_PWR_EnableSEVOnPend)
+           (+++) Any EXTI Line (Internal or External) configured in Event mode
+
+   *** Stop mode ***
+   =================
+    [..]
+      The Stop mode is based on the Cortex-M3 deepsleep mode combined with peripheral
+      clock gating. The voltage regulator can be configured either in normal or low-power mode.
+      In Stop mode, all clocks in the 1.8 V domain are stopped, the PLL, the HSI and the HSE RC 
+      oscillators are disabled. SRAM and register contents are preserved.
+      In Stop mode, all I/O pins keep the same state as in Run mode.
+
+      (+) Entry:
+           The Stop mode is entered using the HAL_PWR_EnterSTOPMode(PWR_REGULATOR_VALUE, PWR_SLEEPENTRY_WFx )
+             function with:
+          (++) PWR_REGULATOR_VALUE= PWR_MAINREGULATOR_ON: Main regulator ON.
+          (++) PWR_REGULATOR_VALUE= PWR_LOWPOWERREGULATOR_ON: Low Power regulator ON.
+          (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFI: enter STOP mode with WFI instruction
+          (++) PWR_SLEEPENTRY_WFx= PWR_SLEEPENTRY_WFE: enter STOP mode with WFE instruction
+      (+) Exit:
+          (++) WFI entry mode, Any EXTI Line (Internal or External) configured in Interrupt mode with NVIC configured
+          (++) WFE entry mode, Any EXTI Line (Internal or External) configured in Event mode.
+
+   *** Standby mode ***
+   ====================
+     [..]
+      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 1.8 V domain is 
+      consequently powered off. The PLL, the HSI oscillator and the HSE oscillator are also 
+      switched off. SRAM and register contents are lost except for registers in the Backup domain 
+      and Standby circuitry
+      
+      (+) Entry:
+        (++) The Standby mode is entered using the HAL_PWR_EnterSTANDBYMode() function.
+      (+) Exit:
+        (++) WKUP pin rising edge, RTC alarm event rising edge, external Reset in 
+             NRSTpin, IWDG Reset
+
+   *** Auto-wakeup (AWU) from low-power mode ***
+       =============================================
+       [..]
+        
+       (+) The MCU can be woken up from low-power mode by an RTC Alarm event, 
+           without depending on an external interrupt (Auto-wakeup mode).
+   
+       (+) RTC auto-wakeup (AWU) from the Stop and Standby modes
+
+           (++) To wake up from the Stop mode with an RTC alarm event, it is necessary to 
+                configure the RTC to generate the RTC alarm using the HAL_RTC_SetAlarm_IT() function.
+
+   *** PWR Workarounds linked to Silicon Limitation ***
+       ====================================================
+       [..]
+       Below the list of all silicon limitations known on STM32F1xx prouct.

+  * @brief   This file provides the high layer firmware functions to manage the
+  *          following functionalities of the USB CDC Class:
+  *           - Initialization and Configuration of high and low layer
+  *           - Enumeration as CDC Device (and enumeration for each implemented memory interface)
+  *           - OUT/IN data transfer
+  *           - Command IN transfer (class requests management)
+  *           - Error management

+  *                                CDC Class Driver Description
+  *          ===================================================================
+  *           This driver manages the "Universal Serial Bus Class Definitions for Communications Devices
+  *           Revision 1.2 November 16, 2007" and the sub-protocol specification of "Universal Serial Bus
+  *           Communications Class Subclass Specification for PSTN Devices Revision 1.2 February 9, 2007"
+  *           This driver implements the following aspects of the specification:
+  *             - Device descriptor management
+  *             - Configuration descriptor management
+  *             - Enumeration as CDC device with 2 data endpoints (IN and OUT) and 1 command endpoint (IN)
+  *             - Requests management (as described in section 6.2 in specification)
+  *             - Abstract Control Model compliant
+  *             - Union Functional collection (using 1 IN endpoint for control)
+  *             - Data interface class
+  *
+  *           These aspects may be enriched or modified for a specific user application.
+  *
+  *            This driver doesn't implement the following aspects of the specification
+  *            (but it is possible to manage these features with some modifications on this driver):
+  *             - Any class-specific aspect relative to communication classes should be managed by user application.
+  *             - All communication classes other than PSTN are not managed
