<h2 id="run">Running a new thread</h2>
<p>
This is a sample to create and run a new thread in the same task.

<pre>
int thread_run(void *start, void *stack, thread_t *th)
{
        thread_t t;
        int err;

}
</pre>


<h2 id="ptmr">Periodic timer</h2>
<p>
This is a sample to show a message per 100msec starting after 5sec.

                sys_log("Hello!\n");
