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___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gaee93d929beb350f16e5cc7fa602e229f">osThreadDef</a> but may be changed during execution using the function <a class="el" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#ga0dfb90ccf1f6e4b54b9251b12d1cbc8b">osThreadSetPriority</a>.</li> -<li>The <b>RUNNING</b> thread transfers into the <b>WAITING</b> state when it is waiting for an event.</li> -<li>Active threads can be terminated any time using the function <a class="el" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gaea135bb90eb853eff39e0800b91bbeab">osThreadTerminate</a>.

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 complained 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> -<dl><dt><b>Enumerator: </b></dt><dd><table border="0" cellspacing="2" cellpadding="0"> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa549e79a43ff4f8b2b31afb613f5caa81"></a>osPriorityIdle</em> </td><td> -<p>priority: idle (lowest) </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa61cb822239ac8f66dfbdc7291598a3d4"></a>osPriorityLow</em> </td><td> -<p>priority: low </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa193b650117c209b4a203954542bcc3e6"></a>osPriorityBelowNormal</em> </td><td> -<p>priority: below normal </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa45a2895ad30c79fb97de18cac7cc19f1"></a>osPriorityNormal</em> </td><td> -<p>priority: normal (default) </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa17b36cd9cd38652c2bc6d4803990674b"></a>osPriorityAboveNormal</em> </td><td> -<p>priority: above normal </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa914433934143a9ba767e59577c56e6c2"></a>osPriorityHigh</em> </td><td> -<p>priority: high </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aa1485dec3702434a1ec3cb74c7a17a4af"></a>osPriorityRealtime</em> </td><td> -<p>priority: realtime (highest) </p> -</td></tr> -<tr><td valign="top"><em><a class="anchor" id="ga7f2b42f1983b9107775ec2a1c69a849aae35f5e2f9c64ad346822521b643bdea4"></a>osPriorityError</em> </td><td> -<p>system cannot determine priority or thread has illegal priority </p> -</td></tr> -</table> -</dd> -</dl> - -</div> -</div> -<h2 class="groupheader">Function Documentation</h2> -<a class="anchor" id="gac59b5713cb083702dce759c73fd90dff"></a> -<div class="memitem"> -<div class="memproto"> - <table class="memname"> - <tr> - <td class="memname"><a class="el" href="cmsis__os_8h.html#adfeb153a84a81309e2d958268197617f">osThreadId</a> osThreadCreate </td> - <td>(</td> - <td class="paramtype">const <a class="el" href="structos_thread_def__t.html">osThreadDef_t</a> * </td> - <td class="paramname"><em>thread_def</em>, </td> - </tr> - <tr> - <td class="paramkey"></td> - <td></td> - <td class="paramtype">void * </td> - <td class="paramname"><em>argument</em> </td> - </tr> - <tr> - <td></td> - <td>)</td> - <td></td><td></td> - </tr> - </table> -</div><div class="memdoc"> -<dl class="params"><dt>Parameters</dt><dd> - <table class="params"> - <tr><td class="paramdir">[in]</td><td class="paramname">thread_def</td><td>thread definition referenced with <a class="el" href="group___c_m_s_i_s___r_t_o_s___thread_mgmt.html#gaf0c7c6b5e09f8be198312144b5c9e453">osThread</a>. </td></tr> - <tr><td class="paramdir">[in]</td><td class="paramname">argument</td><td>pointer that is passed to the thread function as start argument. </td></tr> - </table> - </dd> -</dl> -<dl class="section return"><dt>Returns</dt><dd>thread ID for reference by other functions or NULL in case of error. </dd></dl> -<dl class="section note"><dt>Note</dt><dd>MUST REMAIN UNCHANGED: <b>osThreadCreate</b> shall be consistent in every CMSIS-RTOS.</dd></dl> -<p>Start a thread function by adding it to the Active Threads list and set it to state <b>READY</b>.
