* This is the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

* qualifier can be omitted in order to provide a moderate performance
* improvement without adversely affecting functional behaviour. The assembly

/*
* A sample implementation of pvPortMalloc() that allows the heap to be defined
* across multiple non-contigous blocks and combines (coalescences) adjacent
* memory blocks as they are freed.
*
* See heap_1.c, heap_2.c, heap_3.c and heap_4.c for alternative
* implementations, and the memory management pages of http://www.FreeRTOS.org
* for more information.
*
* Usage notes:
*
* vPortDefineHeapRegions() ***must*** be called before pvPortMalloc().
* pvPortMalloc() will be called if any task objects (tasks, queues, event
* groups, etc.) are created, therefore vPortDefineHeapRegions() ***must*** be
* called before any other objects are defined.
*
* vPortDefineHeapRegions() takes a single parameter. The parameter is an array
* of HeapRegion_t structures. HeapRegion_t is defined in portable.h as
*
* typedef struct HeapRegion
* {
* uint8_t *pucStartAddress; << Start address of a block of memory that will be part of the heap.
* size_t xSizeInBytes; << Size of the block of memory.
* } HeapRegion_t;
*
* The array is terminated using a NULL zero sized region definition, and the
* memory regions defined in the array ***must*** appear in address order from
* low address to high address. So the following is a valid example of how
* to use the function.
*
* HeapRegion_t xHeapRegions[] =
* {
* { ( uint8_t * ) 0x80000000UL, 0x10000 }, << Defines a block of 0x10000 bytes starting at address 0x80000000
* { ( uint8_t * ) 0x90000000UL, 0xa0000 }, << Defines a block of 0xa0000 bytes starting at address of 0x90000000
* { NULL, 0 } << Terminates the array.
* };
*
* vPortDefineHeapRegions( xHeapRegions ); << Pass the array into vPortDefineHeapRegions().
*
* Note 0x80000000 is the lower address so appears in the array first.

If the application only uses CMSIS libraries for interrupt
configuration then the correct setting can be achieved on all Cortex-M

There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
The best option depends on the revision of the ARM Cortex-M7 core in use. The
revision is specified by an 'r' number, and a 'p' number, so will look something
like 'r0p1'. Check the documentation for the microcontroller in use to find the
revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
with all core revisions.
The first option is to use the ARM Cortex-M4F port, and the second option is to
use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
the /FreeRTOS/Source/portable/RVDS/ARM_CM4F directory.
If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/RVDS/ARM_CM7/r0p1
directory.

If the application only uses CMSIS libraries for interrupt
configuration then the correct setting can be achieved on all Cortex-M

If you find your application is crashing here then likely causes are
listed below. In addition see http://www.freertos.org/FAQHelp.html for
more tips, and ensure configASSERT() is defined!
http://www.freertos.org/a00110.html#configASSERT
1) Stack overflow -
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
2) Incorrect interrupt priority assignment, especially on Cortex-M
parts where numerically high priority values denote low actual
interrupt priorities, which can seem counter intuitive. See
http://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
of configMAX_SYSCALL_INTERRUPT_PRIORITY on
http://www.freertos.org/a00110.html
3) Calling an API function from within a critical section or when
the scheduler is suspended, or calling an API function that does
not end in "FromISR" from an interrupt.
4) Using a queue or semaphore before it has been initialised or
before the scheduler has been started (are interrupts firing
before vTaskStartScheduler() has been called?).

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and or compiler.
+ The FreeRTOS/Source directory contains the three files that are common to
every port - list.c, queue.c and tasks.c. The kernel is contained within these
three files. croutine.c implements the optional co-routine functionality - which
is normally only used on very memory limited systems.
+ The FreeRTOS/Source/Portable directory contains the files that are specific to
a particular microcontroller and or compiler.
+ The FreeRTOS/Source/include directory contains the real time kernel header
files.
See the readme file in the FreeRTOS/Source/Portable directory for more

;* Description : STM32F10x High Density Value Line Devices vector table
;* for MDK-ARM toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Configure the clock system and also configure the external
;* SRAM mounted on STM32100E-EVAL board to be used as data
;* memory (optional, to be enabled by user)
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM3 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

;* File Name : startup_stm32f10x_xl.s
;* Author : MCD Application Team
;* Version : V3.5.0
;* Date : 11-March-2011
;* Description : STM32F10x XL-Density Devices vector table for MDK-ARM
;* toolchain.
;* This module performs:
;* - Set the initial SP
;* - Set the initial PC == Reset_Handler
;* - Set the vector table entries with the exceptions ISR address
;* - Configure the clock system and also configure the external
;* SRAM mounted on STM3210E-EVAL board to be used as data
;* memory (optional, to be enabled by user)
;* - Branches to __main in the C library (which eventually
;* calls main()).
;* After Reset the CortexM3 processor is in Thread mode,
;* priority is Privileged, and the Stack is set to Main.

****************************************************************************************
*
* 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
* (RM0008).
* - 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 I2Cx_ER_IRQHandler()
* 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 communication status.
*
*
* 2) Advanced state monitoring:
* 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 limitations of I2C_GetFlagStatus() function (see below).
* The returned value could be compared to events already defined in the
* library (stm32f10x_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() 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.
