-==========================================================
-CMSIS defines for a Cortex-M Microcontroller System:
-
- * A common way to access peripheral registers and a
- common way to define exception vectors.
- * The register names of the Core Peripherals and the
- names of the Core Exception Vectors.
- * An device independent interface for RTOS Kernels
- including a debug channel.
-
-By using CMSIS compliant software components, the user can
-easier re-use template code. CMSIS is intended to enable the
-combination of software components from multiple middleware
-vendors.
-
-This project contains appropriate files for this MCU family
-taken from CMSIS. A full copy of the CMSIS files can be found
-within your tools installation directory. More information on
-CMSIS can be found at:

-<h1>Changes to CMSIS version V1.20</h1>
-
-<hr>
-
-<h2>1. Removed CMSIS Middelware packages</h2>
-<p>
- CMSIS Middleware is on hold from ARM side until a agreement between all CMSIS partners is found.
-</p>
-
-<h2>2. SystemFrequency renamed to SystemCoreClock</h2>
-<p>
- The variable name <strong>SystemCoreClock</strong> is more precise than <strong>SystemFrequency</strong>
- because the variable holds the clock value at which the core is running.
-</p>
-
-<h2>3. Changed startup concept</h2>
-<p>
- The old startup concept (calling SystemInit_ExtMemCtl from startup file and calling SystemInit
- from main) has the weakness that it does not work for controllers which need a already
- configuerd clock system to configure the external memory controller.
-</p>
-
-<h3>Changed startup concept</h3>
-<ul>
- <li>
- SystemInit() is called from startup file before <strong>premain</strong>.
- </li>
- <li>
- <strong>SystemInit()</strong> configures the clock system and also configures
- an existing external memory controller.
- </li>
- <li>
- <strong>SystemInit()</strong> must not use global variables.
- </li>
- <li>
- <strong>SystemCoreClock</strong> is initialized with a correct predefined value.
- </li>
- <li>
- Additional function <strong>void SystemCoreClockUpdate (void)</strong> is provided.<br>
- <strong>SystemCoreClockUpdate()</strong> updates the variable <strong>SystemCoreClock</strong>
- and must be called whenever the core clock is changed.<br>
- <strong>SystemCoreClockUpdate()</strong> evaluates the clock register settings and calculates
- the current core clock.
- </li>
-</ul>
-
-
-<h2>4. Advanced Debug Functions</h2>
-<p>
- ITM communication channel is only capable for OUT direction. To allow also communication for
- IN direction a simple concept is provided.
-</p>
-<ul>
- <li>
- Global variable <strong>volatile int ITM_RxBuffer</strong> used for IN data.
- </li>
- <li>
- Function <strong>int ITM_CheckChar (void)</strong> checks if a new character is available.
- </li>
- <li>
- Function <strong>int ITM_ReceiveChar (void)</strong> retrieves the new character.
- </li>
-</ul>
-
-<p>
- For detailed explanation see file <strong>CMSIS debug support.htm</strong>.
-</p>
-
-
-<h2>5. Core Register Bit Definitions</h2>
-<p>
- Files core_cm3.h and core_cm0.h contain now bit definitions for Core Registers. The name for the
- defines correspond with the Cortex-M Technical Reference Manual.
-</p>
-<p>
- e.g. SysTick structure with bit definitions
-</p>
-<pre>
-/** @addtogroup CMSIS_CM3_SysTick CMSIS CM3 SysTick
- memory mapped structure for SysTick
- @{
- */
-typedef struct
-{

- __IO uint32_t VAL; /*!< Offset: 0x08 SysTick Current Value Register */
- __I uint32_t CALIB; /*!< Offset: 0x0C SysTick Calibration Register */
-} SysTick_Type;

-/*@}*/ /* end of group CMSIS_CM3_SysTick */</pre>
-
-<h2>7. DoxyGen Tags</h2>
-<p>
- DoxyGen tags in files core_cm3.[c,h] and core_cm0.[c,h] are reworked to create proper documentation
- using DoxyGen.
-</p>
-
-<h2>8. Folder Structure</h2>
-<p>
- The folder structure is changed to differentiate the single support packages.
-</p>
-
- <ul>
- <li>CM0</li>
- <li>CM3
- <ul>
- <li>CoreSupport</li>
- <li>DeviceSupport</li>

- </li>
- </ul>
- </li>
-
- <li>Documentation</li>
- </ul>
-
-<h2>9. Open Points</h2>
-<p>
- Following points need to be clarified and solved:
-</p>
-<ul>
- <li>
- <p>
- Equivalent C and Assembler startup files.
- </p>
- <p>
- Is there a need for having C startup files although assembler startup files are
- very efficient and do not need to be changed?
- <p/>
- </li>
- <li>
- <p>
- Placing of HEAP in external RAM.
- </p>
- <p>
- It must be possible to place HEAP in external RAM if the device supports an
- external memory controller.
- </p>
- </li>
- <li>
- <p>
- Placing of STACK /HEAP.
- </p>
- <p>
- STACK should always be placed at the end of internal RAM.
- </p>
- <p>
- If HEAP is placed in internal RAM than it should be placed after RW ZI section.
- </p>
- </li>
- <li>
- <p>
- Removing core_cm3.c and core_cm0.c.
- </p>
- <p>
- On a long term the functions in core_cm3.c and core_cm0.c must be replaced with
- appropriate compiler intrinsics.
- </p>
- </li>
-</ul>
-
-
-<h2>10. Limitations</h2>
-<p>
- The following limitations are not covered with the current CMSIS version:
-</p>
-<ul>
- <li>
- No <strong>C startup files</strong> for ARM toolchain are provided.
- </li>
- <li>
- No <strong>C startup files</strong> for GNU toolchain are provided.
- </li>
- <li>
- No <strong>C startup files</strong> for IAR toolchain are provided.
- </li>
- <li>
- No <strong>Tasking</strong> projects are provided yet.
- </li>
-</ul>

-<h1>CMSIS Debug Support</h1>
-
-<hr>
-
-<h2>Cortex-M3 ITM Debug Access</h2>
-<p>
- The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that provides together with
- the Serial Viewer Output trace capabilities for the microcontroller system. The ITM has
- 32 communication channels which are able to transmit 32 / 16 / 8 bit values; two ITM
- communication channels are used by CMSIS to output the following information:
-</p>
-<ul>
- <li>ITM Channel 0: used for printf-style output via the debug interface.</li>
- <li>ITM Channel 31: is reserved for RTOS kernel awareness debugging.</li>
-</ul>
-
-<h2>Debug IN / OUT functions</h2>
-<p>CMSIS provides following debug functions:</p>
-<ul>
- <li>ITM_SendChar (uses ITM channel 0)</li>
- <li>ITM_ReceiveChar (uses global variable)</li>
- <li>ITM_CheckChar (uses global variable)</li>
-</ul>
-
-<h3>ITM_SendChar</h3>
-<p>
- <strong>ITM_SendChar</strong> is used to transmit a character over ITM channel 0 from
- the microcontroller system to the debug system. <br>
- Only a 8 bit value is transmitted.
-</p>
-<pre>
-static __INLINE uint32_t ITM_SendChar (uint32_t ch)
-{
- /* check if debugger connected and ITM channel enabled for tracing */
- if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
- (ITM->TCR & ITM_TCR_ITMENA) &&
- (ITM->TER & (1UL << 0)) )
- {
- while (ITM->PORT[0].u32 == 0);
- ITM->PORT[0].u8 = (uint8_t)ch;
- }
- return (ch);
-}</pre>
-
-<h3>ITM_ReceiveChar</h3>
-<p>
- ITM communication channel is only capable for OUT direction. For IN direction
- a globel variable is used. A simple mechansim detects if a character is received.
- The project to test need to be build with debug information.
-</p>
-
-<p>
- The globale variable <strong>ITM_RxBuffer</strong> is used to transmit a 8 bit value from debug system
- to microcontroller system. <strong>ITM_RxBuffer</strong> is 32 bit wide to enshure a proper handshake.
-</p>
-<pre>
-extern volatile int ITM_RxBuffer; /* variable to receive characters */
-</pre>
-<p>
- A dedicated bit pattern is used to determin if <strong>ITM_RxBuffer</strong> is empty
- or contains a valid value.
-</p>
-<pre>
-#define ITM_RXBUFFER_EMPTY 0x5AA55AA5 /* value identifying ITM_RxBuffer is ready for next character */
-</pre>
-<p>
- <strong>ITM_ReceiveChar</strong> is used to receive a 8 bit value from the debug system. The function is nonblocking.
- It returns the received character or '-1' if no character was available.
-</p>
-<pre>
-static __INLINE int ITM_ReceiveChar (void) {
- int ch = -1; /* no character available */
-
- if (ITM_RxBuffer != ITM_RXBUFFER_EMPTY) {
- ch = ITM_RxBuffer;
- ITM_RxBuffer = ITM_RXBUFFER_EMPTY; /* ready for next character */
- }
-
- return (ch);
-}
-</pre>
-
-<h3>ITM_CheckChar</h3>
-<p>
- <strong>ITM_CheckChar</strong> is used to check if a character is received.
-</p>
-<pre>
-static __INLINE int ITM_CheckChar (void) {
-
- if (ITM_RxBuffer == ITM_RXBUFFER_EMPTY) {
- return (0); /* no character available */
- } else {
- return (1); /* character available */
- }
-}</pre>
-
-
-<h2>ITM Debug Support in uVision</h2>
-<p>
- uVision uses in a debug session the <strong>Debug (printf) Viewer</strong> window to
- display the debug data.
-</p>
-<p>Direction microcontroller system -> uVision:</p>
-<ul>
- <li>
- Characters received via ITM communication channel 0 are written in a printf style
- to <strong>Debug (printf) Viewer</strong> window.
- </li>
-</ul>
-
-<p>Direction uVision -> microcontroller system:</p>
-<ul>
- <li>Check if <strong>ITM_RxBuffer</strong> variable is available (only performed once).</li>
- <li>Read character from <strong>Debug (printf) Viewer</strong> window.</li>
- <li>If <strong>ITM_RxBuffer</strong> empty write character to <strong>ITM_RxBuffer</strong>.</li>
-</ul>
-
-<p class="Note">Note</p>
-<ul>
- <li><p>Current solution does not use a buffer machanism for trasmitting the characters.</p>
- </li>
-</ul>
-
-<h2>RTX Kernel awareness in uVision</h2>
-<p>
- uVision / RTX are using a simple and efficient solution for RTX Kernel awareness.
- No format overhead is necessary.<br>
- uVsion debugger decodes the RTX events via the 32 / 16 / 8 bit ITM write access
- to ITM communication channel 31.
-</p>
-
-<p>Following RTX events are traced:</p>
-<ul>
- <li>Task Create / Delete event
- <ol>
- <li>32 bit access. Task start address is transmitted</li>
- <li>16 bit access. Task ID and Create/Delete flag are transmitted<br>
- High byte holds Create/Delete flag, Low byte holds TASK ID.
- </li>
- </ol>
- </li>
- <li>Task switch event
- <ol>
- <li>8 bit access. Task ID of current task is transmitted</li>
- </ol>
- </li>
-</ul>
-
-<p class="Note">Note</p>
-<ul>
- <li><p>Other RTOS information could be retrieved via memory read access in a polling mode manner.</p>
- </li>
-</ul>

-<h2><a name="1"></a>About</h2>
-
-<p>
- The <strong>Cortex Microcontroller Software Interface Standard (CMSIS)</strong> answers the challenges
- that are faced when software components are deployed to physical microcontroller devices based on a
- Cortex-M0 or Cortex-M3 processor. The CMSIS will be also expanded to future Cortex-M
- processor cores (the term Cortex-M is used to indicate that). The CMSIS is defined in close co-operation
- with various silicon and software vendors and provides a common approach to interface to peripherals,
- real-time operating systems, and middleware components.
-</p>
-
-<p>ARM provides as part of the CMSIS the following software layers that are
-available for various compiler implementations:</p>
-<ul>
- <li><strong>Core Peripheral Access Layer</strong>: contains name definitions,
- address definitions and helper functions to
- access core registers and peripherals. It defines also a device
- independent interface for RTOS Kernels that includes debug channel
- definitions.</li>
-</ul>
-
-<p>These software layers are expanded by Silicon partners with:</p>
-<ul>
- <li><strong>Device Peripheral Access Layer</strong>: provides definitions
- for all device peripherals</li>
- <li><strong>Access Functions for Peripherals (optional)</strong>: provides
- additional helper functions for peripherals</li>
-</ul>
-
-<p>CMSIS defines for a Cortex-M Microcontroller System:</p>
-<ul>
- <li style="text-align: left;">A common way to access peripheral registers
- and a common way to define exception vectors.</li>
- <li style="text-align: left;">The register names of the <strong>Core
- Peripherals</strong> and<strong> </strong>the names of the <strong>Core
- Exception Vectors</strong>.</li>
- <li>An device independent interface for RTOS Kernels including a debug
- channel.</li>
-</ul>
-
-<p>
- By using CMSIS compliant software components, the user can easier re-use template code.
- CMSIS is intended to enable the combination of software components from multiple middleware vendors.
-</p>
-
-<h2><a name="2"></a>Coding Rules and Conventions</h2>
-
-<p>
- The following section describes the coding rules and conventions used in the CMSIS
- implementation. It contains also information about data types and version number information.
-</p>
-
-<h3>Essentials</h3>
-<ul>
- <li>The CMSIS C code conforms to MISRA 2004 rules. In case of MISRA violations,
- there are disable and enable sequences for PC-LINT inserted.</li>
- <li>ANSI standard data types defined in the ANSI C header file
- <strong><stdint.h></strong> are used.</li>
- <li>#define constants that include expressions must be enclosed by
- parenthesis.</li>
- <li>Variables and parameters have a complete data type.</li>
- <li>All functions in the <strong>Core Peripheral Access Layer</strong> are
- re-entrant.</li>
- <li>The <strong>Core Peripheral Access Layer</strong> has no blocking code
- (which means that wait/query loops are done at other software layers).</li>
- <li>For each exception/interrupt there is definition for:
- <ul>
- <li>an exception/interrupt handler with the postfix <strong>_Handler </strong>
- (for exceptions) or <strong>_IRQHandler</strong> (for interrupts).</li>
- <li>a default exception/interrupt handler (weak definition) that contains an endless loop.</li>
- <li>a #define of the interrupt number with the postfix <strong>_IRQn</strong>.</li>
- </ul></li>
-</ul>
-
-<h3>Recommendations</h3>
-
-<p>The CMSIS recommends the following conventions for identifiers.</p>
-<ul>
- <li><strong>CAPITAL</strong> names to identify Core Registers, Peripheral Registers, and CPU Instructions.</li>
- <li><strong>CamelCase</strong> names to identify peripherals access functions and interrupts.</li>
- <li><strong>PERIPHERAL_</strong> prefix to identify functions that belong to specify peripherals.</li>
- <li><strong>Doxygen</strong> comments for all functions are included as described under <strong>Function Comments</strong> below.</li>
-</ul>
-
-<b>Comments</b>
-
-<ul>
- <li>Comments use the ANSI C90 style (<em>/* comment */</em>) or C++ style
- (<em>// comment</em>). It is assumed that the programming tools support today
- consistently the C++ comment style.</li>
- <li><strong>Function Comments</strong> provide for each function the following information:
- <ul>
- <li>one-line brief function overview.</li>
- <li>detailed parameter explanation.</li>
- <li>detailed information about return values.</li>
- <li>detailed description of the actual function.</li>
- </ul>
- <p><b>Doxygen Example:</b></p>
- <pre>
-/**
- * @brief Enable Interrupt in NVIC Interrupt Controller
- * @param IRQn interrupt number that specifies the interrupt
- * @return none.
- * Enable the specified interrupt in the NVIC Interrupt Controller.
- * Other settings of the interrupt such as priority are not affected.
- */</pre>
- </li>
-</ul>
-
-<h3>Data Types and IO Type Qualifiers</h3>
-
-<p>
- The <strong>Cortex-M HAL</strong> uses the standard types from the standard ANSI C header file
- <strong><stdint.h></strong>. <strong>IO Type Qualifiers</strong> are used to specify the access
- to peripheral variables. IO Type Qualifiers are indented to be used for automatic generation of
- debug information of peripheral registers.

-<h4>Device Peripheral Access Layer</h4>
-<p>
- Each peripheral uses a prefix which consists of <strong><device abbreviation>_</strong>
- and <strong><peripheral name>_</strong> to identify peripheral registers that access this
- specific peripheral. The intention of this is to avoid name collisions caused
- due to short names. If more than one peripheral of the same type exists,
- identifiers have a postfix (digit or letter). For example:
-</p>
-<ul>
- <li><device abbreviation>_UART_Type: defines the generic register layout for all UART channels in a device.
- <pre>
-typedef struct
-{
- union {
- __I uint8_t RBR; /*!< Offset: 0x000 Receiver Buffer Register */
- __O uint8_t THR; /*!< Offset: 0x000 Transmit Holding Register */
- __IO uint8_t DLL; /*!< Offset: 0x000 Divisor Latch LSB */
- uint32_t RESERVED0;
- };
- union {
- __IO uint8_t DLM; /*!< Offset: 0x004 Divisor Latch MSB */
- __IO uint32_t IER; /*!< Offset: 0x004 Interrupt Enable Register */
- };
- union {
- __I uint32_t IIR; /*!< Offset: 0x008 Interrupt ID Register */
- __O uint8_t FCR; /*!< Offset: 0x008 FIFO Control Register */
- };
- __IO uint8_t LCR; /*!< Offset: 0x00C Line Control Register */
- uint8_t RESERVED1[7];
- __I uint8_t LSR; /*!< Offset: 0x014 Line Status Register */
- uint8_t RESERVED2[7];
- __IO uint8_t SCR; /*!< Offset: 0x01C Scratch Pad Register */
- uint8_t RESERVED3[3];
- __IO uint32_t ACR; /*!< Offset: 0x020 Autobaud Control Register */
- __IO uint8_t ICR; /*!< Offset: 0x024 IrDA Control Register */

- uint8_t RESERVED6[39];
- __I uint8_t FIFOLVL; /*!< Offset: 0x058 FIFO Level Register */
-} LPC_UART_TypeDef;</pre>
- </li>
- <li><device abbreviation>_UART1: is a pointer to a register structure that refers to a specific UART.
- For example UART1->DR is the data register of UART1.
- <pre>
-#define LPC_UART2 ((LPC_UART_TypeDef *) LPC_UART2_BASE )
-#define LPC_UART3 ((LPC_UART_TypeDef *) LPC_UART3_BASE )</pre>
- </li>
-</ul>
-
-<h5>Minimal Requiements</h5>
-<p>
- To access the peripheral registers and related function in a device the files <strong><em>device.h</em></strong>
- and <strong>core_cm0.h</strong> / <strong>core_cm3.h</strong> defines as a minimum:
-</p>
-<ul>
- <li>The <strong>Register Layout Typedef</strong> for each peripheral that defines all register names.
- Names that start with RESERVE are used to introduce space into the structure to adjust the addresses of
- the peripheral registers. For example:
- <pre>
-typedef struct {
- __IO uint32_t CTRL; /* SysTick Control and Status Register */
- __IO uint32_t LOAD; /* SysTick Reload Value Register */
- __IO uint32_t VAL; /* SysTick Current Value Register */
- __I uint32_t CALIB; /* SysTick Calibration Register */
- } SysTick_Type;</pre>
- </li>
-
- <li>
- <strong>Base Address</strong> for each peripheral (in case of multiple peripherals
- that use the same <strong>register layout typedef</strong> multiple base addresses are defined). For example:
- <pre>
-#define SysTick_BASE (SCS_BASE + 0x0010) /* SysTick Base Address */</pre>
- </li>
-
- <li>
- <strong>Access Definition</strong> for each peripheral (in case of multiple peripherals that use
- the same <strong>register layout typedef</strong> multiple access definitions exist, i.e. LPC_UART0,
- LPC_UART2). For Example:
- <pre>
-#define SysTick ((SysTick_Type *) SysTick_BASE) /* SysTick access definition */</pre>
- </li>
-</ul>
-
-<p>
- These definitions allow to access the peripheral registers from user code with simple assignments like:
-</p>
-<pre>SysTick->CTRL = 0;</pre>
-
-<h5>Optional Features</h5>
-<p>In addition the <em> <strong>device.h </strong></em>file may define:</p>
-<ul>
- <li>
- #define constants that simplify access to the peripheral registers.
- These constant define bit-positions or other specific patterns are that required for the
- programming of the peripheral registers. The identifiers used start with
- <strong><device abbreviation>_</strong> and <strong><peripheral name>_</strong>.
- It is recommended to use CAPITAL letters for such #define constants.
- </li>
- <li>
- Functions that perform more complex functions with the peripheral (i.e. status query before
- a sending register is accessed). Again these function start with
- <strong><device abbreviation>_</strong> and <strong><peripheral name>_</strong>.
- </li>
-</ul>
-
-<h3>core_cm0.h and core_cm0.c</h3>
-<p>
- File <b>core_cm0.h</b> describes the data structures for the Cortex-M0 core peripherals and does

-<h3>startup_<em>device</em></h3>
-<p>
- A template file for <strong>startup_<em>device</em></strong> is provided by ARM for each supported
- compiler. It is adapted by the silicon vendor to include interrupt vectors for all device specific
- interrupt handlers. Each interrupt handler is defined as <strong><em>weak</em></strong> function
- to an dummy handler. Therefore the interrupt handler can be directly used in application software
- without any requirements to adapt the <strong>startup_<em>device</em></strong> file.

- The CMSIS provides access to the NVIC via the register interface structure and several helper
- functions that simplify the setup of the NVIC. The CMSIS HAL uses IRQ numbers (IRQn) to
- identify the interrupts. The first device interrupt has the IRQn value 0. Therefore negative
- IRQn values are used for processor core exceptions.

-<h3>Cortex-M3 ITM Debug Access</h3>
-
-<p>The Cortex-M3 incorporates the Instrumented Trace Macrocell (ITM) that
-provides together with the Serial Viewer Output trace capabilities for the
-microcontroller system. The ITM has 32 communication channels; two ITM
-communication channels are used by CMSIS to output the following information:</p>
-<ul>
- <li>ITM Channel 0: implements the <strong>ITM_SendChar</strong> function
- which can be used for printf-style output via the debug interface.</li>
- <li>ITM Channel 31: is reserved for the RTOS kernel and can be used for
- kernel awareness debugging.</li>
-</ul>
-<p class="Note">Note</p>
-<ul>
- <li><p>The ITM channel 31 is selected for the RTOS kernel since some kernels
- may use the Privileged level for program execution. ITM
- channels have 4 groups with 8 channels each, whereby each group can be
- configured for access rights in the Unprivileged level. The ITM channel 0
- may be therefore enabled for the user task whereas ITM channel 31 may be
- accessible only in Privileged level from the RTOS kernel itself.</p>
- </li>
-</ul>
-
-<p>The prototype of the <strong>ITM_SendChar</strong> routine is shown in the
-table below.</p>
-
-<table class="kt" border="0" cellpadding="0" cellspacing="0">

- previous character send is not transmitted. <br><br>
- Return: the input character 'chr'.</td>
- </tr>
- </tbody>
-</table>
-
-<p>
- Example for the usage of the ITM Channel 31 for RTOS Kernels:
-</p>
-<pre>
- // check if debugger connected and ITM channel enabled for tracing
- if ((CoreDebug->DEMCR & CoreDebug_DEMCR_TRCENA) &&
- (ITM->TCR & ITM_TCR_ITMENA) &&
- (ITM->TER & (1UL << 31))) {
- // transmit trace data
- while (ITM->PORT31_U32 == 0);
- ITM->PORT[31].u8 = task_id; // id of next task
- while (ITM->PORT[31].u32 == 0);
- ITM->PORT[31].u32 = task_status; // status information
- }</pre>

-
-<h3>Cortex-M3 additional Debug Access</h3>
-
-<p>CMSIS provides additional debug functions to enlarge the Cortex-M3 Debug Access.
-Data can be transmitted via a certain global buffer variable towards the target system.</p>
-
-<p>The buffer variable and the prototypes of the additional functions are shown in the
-table below.</p>

- * 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.
- *
- * xLists can only store pointers to xListItems. Each xListItem 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.

- * queue is empty or full.
- *
- * This type of semaphore can be used for pure synchronisation between tasks or
- * between an interrupt and a task. The semaphore need not be given back once
- * obtained, so one task/interrupt can continuously 'give' the semaphore while
- * another continuously 'takes' the semaphore. For this reason this type of
- * semaphore does not use a priority inheritance mechanism. For an alternative
- * that does use priority inheritance see xSemaphoreCreateMutex().
- *
- * @param xSemaphore Handle to the created semaphore. Should be of type xSemaphoreHandle.
- *
- * Example usage:
- <pre>
- xSemaphoreHandle xSemaphore;

- // Semaphore cannot be used before a call to vSemaphoreCreateBinary ().
- // This is a macro so pass the variable in directly.

- * <i>Macro</i> that creates a counting semaphore by using the existing
- * queue mechanism.
- *
- * Counting semaphores are typically used for two things:
- *
- * 1) Counting events.
- *
- * In this usage scenario an event handler will 'give' a semaphore each time
- * an event occurs (incrementing the semaphore count value), and a handler
- * task will 'take' a semaphore each time it processes an event
- * (decrementing the semaphore count value). The count value is therefore
- * the difference between the number of events that have occurred and the
- * number that have been processed. In this case it is desirable for the
- * initial count value to be zero.
- *
- * 2) Resource management.
- *
- * In this usage scenario the count value indicates the number of resources
- * available. To obtain control of a resource a task must first obtain a
- * semaphore - decrementing the semaphore count value. When the count value
- * reaches zero there are no free resources. When a task finishes with the
- * resource it 'gives' the semaphore back - incrementing the semaphore count
- * value. In this case it is desirable for the initial count value to be
- * equal to the maximum count value, indicating that all resources are free.
- *
- * @param uxMaxCount The maximum count value that can be reached. When the
- * semaphore reaches this value it can no longer be 'given'.
- *
- * @param uxInitialCount The count value assigned to the semaphore when it is
- * created.
- *
- * @return Handle to the created semaphore. Null if the semaphore could not be
- * created.

- *

- *
- * INCLUDE_vTaskDelay must be defined as 1 for this function to be available.

- *
- *
- * vTaskDelay() specifies a time at which the task wishes to unblock relative to
- * the time at which vTaskDelay() is called. For example, specifying a block
- * period of 100 ticks will cause the task to unblock 100 ticks after
- * vTaskDelay() is called. vTaskDelay() does not therefore provide a good method
- * of controlling the frequency of a cyclical task as the path taken through the

- * at which vTaskDelay() gets called and therefore the time at which the task
- * next executes. See vTaskDelayUntil() for an alternative API function designed
- * to facilitate fixed frequency execution. It does this by specifying an
- * absolute time (rather than a relative time) at which the calling task should
- * unblock.
- *
- * @param xTicksToDelay The amount of time, in tick periods, that

- * Delay a task until a specified time. This function can be used by cyclical

- *
- * This function differs from vTaskDelay () in one important aspect: vTaskDelay () will

- * calling vTaskDelay () may not be fixed [the task may take a different path though the
- * code between calls, or may get interrupted or preempted a different number of times
- * each time it executes].
