+\mainpage Overview

+

+The CMSIS-RTOS API is a generic RTOS interface for ARM&reg; Cortex&reg;-M processor-based devices. CMSIS-RTOS provides a

+standardized API for software components that require RTOS functionality and gives therefore serious benefits to the users

+and the software industry.

+ - CMSIS-RTOS provides basic features that are required in many applications or technologies such as UML or Java (JVM).

+ - The unified feature set of the CMSIS-RTOS API simplifies sharing of software components and reduces learning efforts.

+ - Middleware components that use the CMSIS-RTOS API are RTOS agnostic. CMSIS-RTOS compliant middleware is easier to adapt.

+ - Standard project templates (such as motor control) of the CMSIS-RTOS API may be shipped with freely available CMSIS-RTOS

+   implementations.

+

+

+\note The CMSIS-RTOS API defines a minimum feature set. Implementations with extended features may be provided by RTOS

+      vendors.

+

+\image html "API_Structure.png" "CMSIS-RTOS API Structure"

+

+A typical CMSIS-RTOS API implementation interfaces to an existing real-time Kernel. The CMSIS-RTOS API provides the following

+attributes and functionalities:

+ - Function names, identifiers, and parameters are descriptive and easy to understand. The functions are powerful and

+   flexible which reduces the number of functions exposed to the user. 

+ - \ref CMSIS_RTOS_ThreadMgmt allows you to define, create, and control threads.

+ - Interrupt Service Routines (ISR) can \ref CMSIS_RTOS_ISR_Calls "call some CMSIS-RTOS functions". When a CMSIS-RTOS

+   function cannot be called from ISR context, it rejects the invocation.

+ - Different thread event types support communication between multiple threads and/or ISR:

+   - \ref CMSIS_RTOS_SignalMgmt "Signal": is a flag that may be used to indicate specific conditions to a thread. Signals can

+     be modified in an ISR or set from other threads. 

+   - \ref CMSIS_RTOS_FlagMgmt "Flag": 

+   - \ref CMSIS_RTOS_Message "Message": is a 32-bit value that can be sent to a thread or an ISR. Messages are buffered in a

+     queue. The message type and queue size is defined in a descriptor.

+   - \ref CMSIS_RTOS_Mail "Mail": is a fixed-size memory block that can be sent to a thread or an ISR. Mails are buffered in

+     a queue and memory allocation is provided. The mail type and queue size is defined in a descriptor.

+ - \ref CMSIS_RTOS_MutexMgmt and \ref CMSIS_RTOS_SemaphoreMgmt are incorporated.

+ - CPU time can be scheduled with the following functionalities:

+   - A \ref CMSIS_RTOS_TimeOutValue "timeout" parameter is incorporated in many CMSIS-RTOS functions to avoid system lockup.

+     When a timeout is specified, the system waits until a resource is available or an event occurs. While waiting, other

+     threads are scheduled.

+   - The \ref osDelay function puts a thread into the state \b WAITING for a specified period of time.

+   - The generic \ref osWait function waits for events that are assigned to a thread.

+   - The \ref osThreadYield provides co-operative thread switching and passes execution to another thread of the same

+     priority.

+

+The CMSIS-RTOS API is designed to optionally incorporate multi-processor systems and/or access protection via the

+ARM&nbsp;Cortex-M Memory Protection Unit (MPU).

+

+In some RTOS implementations threads may execute on different processors and \b Mail and \b Message queues can therefore

+reside in shared memory resources.

+

+The CMSIS-RTOS API encourages the software industry to evolve existing RTOS implementations. Kernel objects are defined and

+accessed using macros. This allows differentiation. RTOS implementations can be different and optimized in various aspects

+towards the Cortex-M processors. Optional features may be for example

+ - Generic \b wait function; i.e. with support of time intervals.

+ - Support of the Cortex-M Memory Protection Unit (MPU).

+ - Zero-copy mail queue.

+ - Support of multi-processor systems.

+ - Support of a DMA controller.

+ - Deterministic context switching.

+ - Round-robin context switching.

+ - Deadlock avoidance, for example with priority inversion.

+ - Zero interrupt latency by using the ARMv7-M instructions LDREX and STREX.

+\page UsingOS Using a CMSIS-RTOS Implementation

+

+A CMSIS-RTOS implementation is typically provided as a library. To add the RTOS functionality to an existing CMSIS-based

+application, the RTOS library (and typically a configuration file) needs to be added. The available functionality of the

+RTOS library is defined in the header file \b cmsis_os.h that is specific for each CMSIS-RTOS implementation.

+

+\image html "CMSIS_RTOS_Files.png" "CMSIS-RTOS File Structure"

+

+Depending on the CMSIS-RTOS implementation, execution may start with the \b main function as the first thread. This has the

+benefit that an application programmer may use other middleware libraries that create threads internally, but the remaining

+part of the user application just uses the \b main thread. Therefore, the usage of the RTOS can be invisible to the

+application programmer, but libraries can use CMSIS-RTOS features.

+

+Once the files are added to a project, the user can start working with the CMSIS-RTOS functions. A code example is provided

+below:

+ 

+<b>Code Example</b>

+\code

+#include "cmsis_os.h"                            // CMSIS-RTOS header file

+ 

+void job1 (void const *argument)  {              // thread function 'job1'

+  while (1)  {

+      :                                          // execute some code

+    osDelay (10);                                // delay execution for 10 milliseconds

+  }

+}

+ 

+osThreadDef(job1, osPriorityAboveNormal, 1, 0);  // define job1 as thread function

+ 

+void job2 (void const *argument)  {              // thread function 'job2'

+  osThreadCreate(osThread(job1),NULL);           // create job1 thread

+  while (1)   {

+    :                                            // execute some code

+  }

+}

+ 

+osThreadDef(job2, osPriorityNormal, 1, 0);       // define job2 as thread function

+ 

+void job3 (void const *argument)  {              // thread function 'job3'

+  while (1)   {

+      :                                          // execute some code

+  }

+}

+ 

+osThreadDef(job3, osPriorityNormal, 1, 0);       // define job3 as thread function

+\section CMSIS_RTOS_TimeOutValue Timeout Value   

+

+The timeout value specifies the number of timer ticks until a timeout or time delay elapses. The value is an upper bound and 

+depends on the actual time elapsed since the last timer tick. 

+

+For a value of \b 1 the system waits until the next timer tick occurs. That means that the actual timeout value can be one

+timer tick less than the specified timeout value.

+

+The following CMSIS-RTOS functions can be called from threads and Interrupt Service Routines (ISR):

+  - \ref osKernelRunning

+  - \ref osSignalSet

+  - \ref osSemaphoreRelease

+  - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree

+  - \ref osMessagePut, \ref osMessageGet

+  - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree

+

+Functions that cannot be called from an ISR are verifying the interrupt status and return, in case they are called

+from an ISR context, the status code \b osErrorISR. In some implementations, this condition might be caught using the HARD

+FAULT vector.

+

+Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISRs at the same time.

+If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive.

+\page cmsis_os_h Header File Template: cmsis_os.h

+

+The file \b cmsis_os.h is a template header file for a CMSIS-RTOS compliant Real-Time Operating System (RTOS).

+Each RTOS that is compliant with CMSIS-RTOS shall provide a specific \b cmsis_os.h header file that represents

+its implementation.

+

+The file cmsis_os.h contains:

+ - CMSIS-RTOS API function definitions

+ - struct definitions for parameters and return types

+ - status and priority values used by CMSIS-RTOS API functions

+ - macros for defining threads and other kernel objects

+

+

+<b>Name conventions and header file modifications</b>

+

+All definitions are prefixed with \b os to give an unique name space for CMSIS-RTOS functions.

+Definitions that are prefixed \b os_ are not used in the application code but local to this header file.

+All definitions and functions that belong to a module are grouped and have a common prefix, i.e. \b osThread.

+

+Definitions that are marked with <b>CAN BE CHANGED</b> can be adapted towards the needs of the actual CMSIS-RTOS

+implementation. These definitions can be specific to the underlying RTOS kernel.

+

+Definitions that are marked with <b>MUST REMAIN UNCHANGED</b> cannot be altered. Otherwise the CMSIS-RTOS implementation is

+no longer compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS

+implementation.

+

+<b>Define and reference object definitions</b>

+

+With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header

+file that is used throughout a project as shown below:

+

+<i>Header File</i>

+\code

+#include <cmsis_os.h>                                         // CMSIS RTOS header file

+

+// Thread definition

+extern void thread_sample (void const *argument);             // function prototype

+osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100);

+

+// Pool definition

+osPoolDef(MyPool, 10, long);

+\endcode

+

+

+This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is

+present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be

+used throughout the whole project.

+

+<i>Example</i>

+\code

+#include "osObjects.h"     // Definition of the CMSIS-RTOS objects

+\endcode

+

+\code

+#define osObjectsExternal  // Objects will be defined as external symbols

+#include "osObjects.h"     // Reference to the CMSIS-RTOS objects

+\page RtosValidation RTOS Validation

+

+ARM offers a <a class=el href="http://www.keil.com/pack" target="_blank">Software Pack</a> for the CMSIS-RTOS Validation.

+The <b>ARM::CMSIS-RTOS_Validation</b> Pack contains the following:

+

+ - Source code of a CMSIS-RTOS Validation Suite along with configuration file.

+ - Documentation of the CMSIS-RTOS Validation Suite.

+ - Example that shows the usage of the CMSIS-RTOS Validation Suite using simulation.

+

+The CMSIS-RTOS Validation Suite is currently available in beta release and performs generic validation of various

+RTOS features. The test cases verify the functional behavior, test invalid parameters and call management 

+functions from ISR.

+

+The following CMSIS-RTOS features can be tested with the current release:

+ - Thread : Create multiple threads, terminate, restart, yield, change priority 

+ - Timer : Create periodic and one-shot timers

+ - GenWait : Call generic wait functions (osDelay and osWait)

+ - WaitFunc : Measure wait ticks (delay, mail, message, mutex, semaphore, signal)

+ 

+Moreover the following inter-thread communication functions can be tested: 

+ - Signal : Verify signal events

+ - Memory Pool : Verify memory allocation

+ - Message Queue : Exchange messages between threads

+ - Mail Queue : Exchange data between threads

+ - Mutex : Synchronize resource access 

+ - Semaphore : Access shared resources 

+ 

+The RTOS Validation output can be printed to a console, output via ITM printf, or output to a memory buffer.

+@brief Define, create, and control thread functions.

+@details 

+The Thread Management function group allows defining, creating, and controlling thread functions in the system. The function

+\b main is a special thread function that is started at system initialization and has the initial priority

+\a osPriorityNormal.

+

+\anchor ThreadStates

+Threads can be in the following states:

+ - \b RUNNING: The thread that is currently running is in the \b RUNNING state. Only one thread at a time can be in this

+   state.

+ - \b READY: Threads which are ready to run are in the \b READY state. Once the \b RUNNING thread has terminated or is

+   \b WAITING, the next \b READY thread with the highest priority becomes the \b RUNNING thread.

+ - \b WAITING: Threads that are waiting for an event to occur are in the \b WAITING state.

+ - \b INACTIVE: Threads that are not created or terminated are in the \b INACTIVE state. These threads typically consume no

+   system resources.

+

+\image html "ThreadStatus.png" "Thread State and State Transitions"

+

+A CMSIS-RTOS assumes that threads are scheduled as shown in the figure <b>Thread State and State Transitions</b>. The thread

+states change as follows:

+ - A thread is created using the function \ref osThreadCreate. This puts the thread into the \b READY or \b RUNNING state

+   (depending on the thread priority).

+ - CMSIS-RTOS is pre-emptive. The active thread with the highest priority becomes the \b RUNNING thread provided it does not

+   wait for any event. The initial priority of a thread is defined with the \ref osThreadDef but may be changed during

+   execution using the function \ref osThreadSetPriority.

+ - The \b RUNNING thread transfers into the \b WAITING state when it is waiting for an event.

+ - Active threads can be terminated any time using the function \ref osThreadTerminate. Threads can terminate also by just

+   returning from the thread function. Threads that are terminated are in the \b INACTIVE state and typically do not consume

+   any dynamic memory resources.

+\addtogroup CMSIS_RTOS_TimerMgmt Timer Management

+\ingroup CMSIS_RTOS

+\brief Create and control timer and timer callback functions.

+\details 

+In addition to the \ref CMSIS_RTOS_Wait CMSIS-RTOS also supports virtual timer objects. These timer objects can

+trigger the execution of a function (not threads). When a timer expires, a callback function is executed to run associated

+code with the timer. The timer number is passed as a parameter to the callback function. Each timer can be configured as a

+one-shot or a  periodic timer. A periodic timer repeats its operation until it is \ref osTimerDelete "deleted" or

+\ref osTimerStop "stopped". All timers can be \ref osTimerStart "started, restarted", or \ref osTimerStop "stopped".

+

+Timers are handled in the thread \b osTimerThread. Callback functions run under control of this thread and may use other

+CMSIS-RTOS API calls.

+

+The figure below shows the behavior of a periodic timer. For one-shot timers, the timer stops after execution of the

+callback function.

+

+\image html "Timer.png" "Behavior of a Periodic Timer"

+

+Working with Timers

+--------------------

+The following steps are required to use a timer:

+-# Define the timers:

+\code

+osTimerDef(one_shot, start_machine);  // when the timer expires, the function start_machine is called

+osTimerDef(periodic, toggle_power);   // when the timer expires, the function toggle_power is called

+osTimerId one_shot_id, periodic_id;

+\endcode

+-# Instantiate and start the timers in an RTOS thread:

+\code

+one_shot_id = osTimerCreate(osTimer(one_shot), osTimerOnce, (void *)0);      // creates a one-shot timer;

+                                                                             // (void*)0 is passed as an argument

+                                                                             // to the callback function

+periodic_id = osTimerCreate(osTimer(periodic), osTimerPeriodic, (void *)5);  // creates a periodic timer;

+                                                                             // (void*)5 is passed as an argument

+                                                                             // to the callback function

+\brief Functions for inter-thread communication.

+In most applications, threads need to \b communicate \b with \b each \b other or \b access \b shared \b resources together.

+There are many ways to exchange data between threads, for example using shared data, polling loops and message passing.

+

+Many resources in a microcontroller can be considered as \b serially-reusable. This means that they can be used repeatedly by

+different threads, but only by \b one \b thread \b at \b a \b time (for example communication peripherals such as \b UARTs,

+\b memory, and \b files that need to be modified).

+

+

+The CMSIS-RTOS API provides different means to pass messages between threads to make inter-thread communication more

+efficient. Also, resource sharing is inherently supported. The following methods are available to the user:

+\ingroup CMSIS_RTOS_InterThread

+\brief Synchronize threads using signals.

+\details 

+Signals are used to trigger execution states between threads. The signal management functions in CMSIS-RTOS allow you to

+control or wait for signal flags. Each thread has up to 31 assigned signal flags. The maximum number of signal flags is

+defined in the cmsis_os.h file (<b>\#define osFeature_Signals</b>).

+

+A thread

+- can wait for signals to be set (using \ref osSignalWait). Using this function, it enters the

+  \ref ThreadStates "WAITING" state. The \ref osSignalWait parameter \a signals defines the signals that are required to put

+  the thread back into \b READY state.

+- may set one or more flags in any other given thread (using \ref osSignalSet).

+- may clear its own signals or the signals of other threads (using \ref osSignalClear).

+

+When a thread wakes up and resumes execution, its signal flags are automatically cleared. 

+

+Working with Signals

+--------------------

+Here is a simple example that shows how two thread can communicate with each others using signals:

+

+\image html simple_signal.png "Simple signal event communication"

+

+The following steps are required to use signals:

+-# In the thread (for example thread ID \c tid_thread1) that is supposed to wait for a signal, call the wait function:

+\code

+osSignalWait (0x0001, osWaitForever); // wait forever for the signal 0x0001

+\endcode

+-# In another thread (or threads) that are supposed to wake the waiting thread up call:

+\code

+osSignalSet (tid_thread1, 0x0001);    // set the signal 0x0001 for thread tid_thread1

+osDelay (1000);                       // wait for 1 second

+\endcode

+@addtogroup CMSIS_RTOS_Message Message Queue

+@ingroup CMSIS_RTOS_InterThread

+@brief Exchange messages between threads in a FIFO-like operation.

+@details 

+\b Message \b passing is another basic communication model between threads. In the message passing model, one thread sends

+data explicitly, while another thread receives it. The operation is more like some kind of I/O rather than a direct access to

+information to be shared. In CMSIS-RTOS, this mechanism is called s \b message \b queue. The data is passed from one thread

+to another in a FIFO-like operation. Using message queue functions, you can control, send, receive, or wait for messages. The

+data to be passed can be of integer or pointer type:

+

+\image html "MessageQueue.png" "CMSIS-RTOS Message Queue"

+

+Compared to a \ref CMSIS_RTOS_PoolMgmt, message queues are less efficient in general, but solve a broader range of problems.

+Sometimes, threads do not have a common address space or the use of shared memory raises problems, such as mutual exclusion.

+

+Working with Message Queues

+---------------------------

+Follow these steps to create and use a message queue:

+-# Setup the message queue:

+\code

+osMessageQDef(message_q, 5, uint32_t); // Declare a message queue

+osMessageQId (message_q_id);           // Declare an ID for the message queue

+\endcode

+-# Then, create the message queue in a thread:

+\code

+message_q_id = osMessageCreate(osMessageQ(message_q), NULL);

+\endcode

+-# Fill the message queue with data:

+\code

+uint32_t data = 512;

+ 

+osMailPut(message_q_id, data, osWaitForever);

+-# From the receiving thread access the data using:

+\brief Manage thread-safe fixed-size blocks of dynamic memory.

+\details

+\b Memory \b pools are fixed-size blocks of memory that are thread-safe. They operate much faster than the dynamically

+allocated heap and do not suffer from fragmentation. Being thread-safe, they can be accessed from threads and ISRs alike.

+

+\b Shared \b memory is one of the basic models to exchange information between threads. Using memory pools for exchanging

+data, you can share more complex objects between threads if compared to a \ref CMSIS_RTOS_Message. Memory pool management

+functions are used to define and manage such fixed-sized memory pools.

+

+Working with Memory Pools

+-------------------------

+Follow these steps to create and use a memory pool:

+-# Declare a data structure that combines a number of elements:

+typedef struct {

+  uint32_t length;

+  uint32_t width;

+  uint32_t height;

+  uint32_t weight;

+} properties_t;

+\endcode

+-# Declare a memory pool of these objects as a block of memory:

+\code

+osPoolDef (object_pool, 10, properties_t);  // Declare memory pool

+osPoolId  (object_pool_id);                 // Memory pool ID

+\endcode

+-# Then, create the memory pool in a thread:

+\code

+object_pool_id = osPoolCreate(osPool(object_pool));

+\endcode

+-# Allocate the pool within a thread and fill it with data:

+\addtogroup CMSIS_RTOS_Mail Mail Queue

+\ingroup CMSIS_RTOS_InterThread

+\brief Exchange data between threads using a queue of memory blocks.

+\details

+

+A \b mail \b queue resembles a \ref CMSIS_RTOS_Message, but the data that is being transferred consists of memory blocks that

+need to be allocated (before putting data in) and freed (after taking data out). The mail queue uses a

+\ref CMSIS_RTOS_PoolMgmt to create formatted memory blocks and passes pointers to these blocks in a message queue. This

+allows the data to stay in an allocated memory block while only a pointer is moved between the separate threads. This is an

+advantage over \ref CMSIS_RTOS_Message "messages" that can transfer only a 32-bit value or a pointer. Using the mail queue

+functions, you can control, send, receive, or wait for mail.

+

+\image html "MailQueue.png" "CMSIS-RTOS Mail Queue"

+

+Working with Mail Queues

+---------------------------

+Follow these steps to create and use a mail queue:

+-# Declare a data structure that combines a number of elements:

+\code

+typedef struct {

+  uint32_t length;

+  uint32_t width;

+  uint32_t height;

+  uint32_t weight;

+} properties_t;

+\endcode

+-# Declare a mail queue made up of these objects:

+\code

+osMailQDef (object_pool_q, 10, properties_t);  // Declare mail queue

+osMailQId  (object_pool_q_id);                 // Mail queue ID

+\endcode

+-# Then, create the mail pool in a thread:

+\code

+object_pool_q_id = osMailCreate(osMailQ(object_pool_q), NULL);

+\endcode

+-# Allocate the mail queue within a thread and fill it with data:

+\code

+properties_t *object_data;

+*object_data = (properties_t *) osMailAlloc(object_pool_q_id, osWaitForever);

+ 

+object_data->length = 100;

+object_data->width = 10;

+object_data->height = 23;

+object_data->weight = 1000;

+\endcode

+-# Pass the pointer to the mail queue to another thread:

+\code

+osMailPut(object_pool_q_id, object_data);

+\endcode

+-# Access the data in another thread:

+\code

+osEvent event = osMailGet(properties_q_id, osWaitForever);

+properties_t *received = (properties_t *)event.value.p;       // ".p" indicates that the message is a pointer

+my_length(received->length);

+\endcode

+-# Once the data has been used, the memory block must be freed so that the memory pool can be reused

+\code

+osMailFree(object_pool_q_id, received);

+\addtogroup CMSIS_RTOS_MutexMgmt Mutexes

+\ingroup CMSIS_RTOS_InterThread

+\brief Synchronize resource access using Mutual Exclusion (Mutex).

+\details 

+<b>Mutual exclusion</b> (widely known as \b Mutex) is used in various operating systems for resource management. Many

+resources in a microcontroller device can be used repeatedly, but only by one thread at a time (for example communication

+channels, memory, and files). Mutexes are used to protect access to a shared resource. A mutex is created and then passed

+between the threads (they can acquire and release the mutex).

+

+\image html "Mutex.png" "CMSIS-RTOS Mutex"

+

+A mutex is a special version of a \ref CMSIS_RTOS_SemaphoreMgmt "semaphore". Like the semaphore, it is a container for

+tokens. But instead of being able to have multiple tokens, a mutex can only carry one (representing the resource). Thus, a

+mutex token is binary and bounded. The advantage of a mutex is that it introduces thread ownership. When a thread acquires a

+mutex and becomes its owner, subsequent mutex acquires from that thread will succeed immediately without any latency. Thus,

+mutex acquires/releases can be nested.

+

+\note

+- Mutex management functions cannot be called from interrupt service routines (ISR), unlike a binary semaphore that can be

+  released from an ISR.

+

+Working with Mutexes

+--------------------

+To use mutexes, you need to follow these steps for creating and using them:

+-# Declare the mutex container and initialize the mutex:

+\code

+osMutexDef (uart_mutex);    // Declare mutex

+osMutexId  (uart_mutex_id); // Mutex ID

+\endcode

+-# Create the mutex in a thread:

+\code

+uart_mutex_id = osMutexCreate(osMutex(uart_mutex));

+\endcode

+-# Acquire the mutex when peripheral access is required:

+\code

+osMutexWait(uart_mutex_id, osWaitForever);

+\endcode

+-# When finished with the peripheral access, release the mutex:

+\code

+osMutexRelease(uart_mutex_id);

+\addtogroup CMSIS_RTOS_SemaphoreMgmt Semaphores

+\ingroup CMSIS_RTOS_InterThread

+\brief Access shared resources simultaneously from different threads.

+\details 

+Semaphores are used to manage and protect access to shared resources. Semaphores are very similar to

+\ref CMSIS_RTOS_MutexMgmt "Mutexes". Whereas a Mutex permits just one thread to access a shared resource at a

+time, a semaphore can be used to permit a fixed number of threads to access a pool of shared resources. Using semaphores,

+access to a group of identical peripherals can be managed (for example multiple DMA channels).

+

+\image html "Semaphore.png" "CMSIS-RTOS Semaphore"

+

+A semaphore object should be initialized to the maximum number of available tokens. This number of available resources is

+specified as parameter of the \ref osSemaphoreCreate function. Each time a semaphore token is obtained with

+\ref osSemaphoreWait, the semaphore count is decremented. When the semaphore count is 0, no semaphore token can be obtained.

+The thread that tries to obtain the semaphore token needs to wait until the next token is free. Semaphores are released with

+\ref osSemaphoreRelease incrementing the semaphore count.

+

+\note Semaphore tokens can be acquired from threads and released from threads and ISRs.

+

+Working with Semaphores

+--------------------

+Follow these steps to create and use a semaphore:

+-# Declare the semaphore container and initialize the semaphore:

+\code

+osSemaphoreDef (my_semaphore);    // Declare semaphore

+osSemaphoreId  (my_semaphore_id); // Semaphore ID

+\endcode

+-# Initialize the semaphore container with a number of tokens within a thread:

+\code

+my_semaphore_id = osSemaphoreCreate(osSemaphore(my_semaphore), 4);  // Create semaphore with 4 tokens

+\endcode

+\b Important: semaphore tokens can be created and destroyed as threads run. This means that can initialize a semaphore with

+zero tokens and then use one thread to add/create tokens to the semaphore while a second thread removes them. In this way you

+can distinguish between producer and consumer threads.

+-# Acquire a token from the semaphore container:

+\code

+osSemaphoreWait(my_semaphore_id, osWaitForever);

+\endcode

+-# When finished using the semaphore resource, send the token back to the semaphore container:

+\code

+osSemaphoreRelease(my_semaphore_id);

+\endcode

+

+Semaphore Use Cases

+-------------------

+Due to their flexibility, semaphores cover a wide range of synchronizing applications. At the same time, they are perhaps the

+most challenging RTOS object to understand. The following explains a use case for semaphores, taken from the book

+<a href="http://www.greenteapress.com/semaphores/" target="_blank">The Little Book Of Semaphores</a> by Allen B. Downey which

+is available for free download.

+

+<b>Non-binary Semaphore (Multiplex)</b>

+

+A multiplex limits the number of threads that can access a critical section of code. For example, this could be a function

+accessing DMA resources which can only support a limited number of calls.

+

+To allow multiple threads to run the function, initialize a semaphore to the maximum number of threads that can be allowed.

+The number of tokens in the semaphore represents the number of additional threads that may enter. If this number is zero,

+then the next thread trying to access the function will have to wait until one of the other threads exits and releases its

+token. When all threads have exited the token number is back to n. Ths following example shows the code for one of the

+threads that might access the resource:

+

+\code

+osSemaphoreDef(multiplex);

+osSemaphoreId (multiplex_id);

+ 

+void thread_n (void)

+  {

+    multiplex_id = osSemaphoreCreate(osSemaphore(multiplex), 3);

+    while(1)

+      {

+        osSemaphoreWait(multiplex_id, osWaitForever);

+        // do something

+        osSemaphoreRelease(multiplex_id);

+      }

+  }

+\endcode
