Although it&rsquo;s perfectly possible to use some forms of cooperative scheduling to execute firmware activities, basically this not convenient especially when dealing with low level events related to hardware (eg. interrupt handling) and aspects related to synchronization. As long as your firmware starts to grow, you&rsquo;ll need constructs to synchronize firmware activities, like queues or semaphores. Moreover, especially when dealing with low-power devices, a busy spin (while(some condition);) it&rsquo;s not the best solution if you have to fight with mAh.</p>
