Each such co-routine + * uses a different block period. A single 'flash' co-routine is also created + * that blocks on the same queue, waiting for the number of the next LED it + * should flash. Upon receiving a number it simply toggle the instructed LED + * then blocks on the queue once more. In this manner each LED from LED 0 to + * LED N-1 is caused to flash at a different rate. + * + * The 'fixed delay' co-routines are created with co-routine priority 0. The + * flash co-routine is created with co-routine priority 1. This means that + * the queue should never contain more than a single item. This is because + * posting to the queue will unblock the 'flash' co-routine, and as this has + * a priority greater than the tasks posting to the queue it is guaranteed to + * have emptied the queue and blocked once again before the queue can contain + * any more date. An error is indicated if an attempt to post data to the + * queue fails - indicating that the queue is already full. + * + */ + +/* Scheduler includes. */ +#include "FreeRTOS.h" +#include "croutine.h" +#include "queue.h" + +/* Demo application includes. */ +#include "partest.h" +#include "crflash.h" + +/* The queue should only need to be of length 1.
