<p>Threads can be in the following states:</p>
|
||
|
|
<ul>
|
||
|
|
<li><b>RUNNING:</b> The thread that is currently running is in the <b>RUNNING</b> state. Only one thread at a time can be in this state.</li>
|
||
|
|
<li><b>READY:</b> Threads which are ready to run are in the <b>READY</b> state. Once the <b>RUNNING</b> thread has terminated, or is <b>BLOCKED</b>, the next <b>READY</b> thread with the highest priority becomes the <b>RUNNING</b> thread.</li>
|
||
|
|
<li><b>BLOCKED:</b> Threads that are blocked either delayed, waiting for an event to occur or suspended are in the <b>BLOCKED</b> state.</li>
|
||
|
|
<li><b>TERMINATED:</b> When <a class="el" href="group__CMSIS__RTOS__ThreadMgmt.html#ga2f8ba6dba6e9c065a6e236ffd410d74a">osThreadTerminate</a> is called, threads are <b>TERMINATED</b> with resources not yet released.</li>
|

<li><b>INACTIVE:</b> Threads that are not created or have been terminated with all resources released are in the <b>INACTIVE</b> state.</li>

Thread State and State Transitions</div></div>
|
||
|
|
<p>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:</p>
|
||
|
|
<ul>
|
||
|
|
<li>A thread is created using the function <a class="el" href="group__CMSIS__RTOS__ThreadMgmt.html#ga48d68b8666d99d28fa646ee1d2182b8f">osThreadNew</a>. This puts the thread into the <b>READY</b> or <b>RUNNING</b> state (depending on the thread priority).</li>
|
||
|
|
<li>CMSIS-RTOS is pre-emptive. The active thread with the highest priority becomes the <b>RUNNING</b> thread provided it does not wait for any event. The initial priority of a thread is defined with the <a class="el" href="group__CMSIS__RTOS__ThreadMgmt.html#structosThreadAttr__t">osThreadAttr_t</a> but may be changed during execution using the function <a class="el" href="group__CMSIS__RTOS__ThreadMgmt.html#ga861a420fb2d643115b06622903fb3bfb">osThreadSetPriority</a>.</li>
|
||
|
|
<li>The <b>RUNNING</b> thread transfers into the <b>BLOCKED</b> state when it is delayed, waiting for an event or suspended.</li>
|
||
|
|
<li>Active threads can be terminated any time using the function <a class="el" href="group__CMSIS__RTOS__ThreadMgmt.html#ga2f8ba6dba6e9c065a6e236ffd410d74a">osThreadTerminate</a>. Threads can terminate also by just returning from the thread function. Threads that are terminated are in the <b>INACTIVE</b> state and typically do not consume any dynamic memory resources.</li>
|
||
|
|
</ul>

<p>Create a thread out of the function thread1 using all default values for thread attributes and memory from the <a class="el" href="theory_of_operation.html#GlobalMemoryPool">Global Memory Pool</a>.</p>

<p>The <b>osPriority_t</b> value specifies the priority for a thread. The default thread priority should be <em>osPriorityNormal</em>. If a Thread is active that has a higher priority than the currently executing thread, then a thread switch occurs immediately to execute the new task.</p>

<p>To prevent from a priority inversion, a CMSIS-RTOS compliant OS may optionally implement a <b>priority inheritance</b> method. A priority inversion occurs when a high priority thread is waiting for a resource or event that is controlled by a thread with a lower priority.</p>
