Code Issues Projects Releases Wiki Activity

Prepare for a FreeRTOS V9 release candidate:

Browse Source 
- Remove the standard demo files that used the [long since deprecated] alternative API.
- Add standard demo task that tests the new xTaskAbortDelay() function.
- Update the Win32 Visual Studio project to use Visual Studio 2015 Community Edition.
- Rename the xGenericListItem TCB member to xStateListItem as it better describes the member's purpose.

/*
* This is a version of BlockQ.c that uses the alternative (Alt) API.
*
* Creates six tasks that operate on three queues as follows:
*
* The first two tasks send and receive an incrementing number to/from a queue.
* One task acts as a producer and the other as the consumer. The consumer is a
* higher priority than the producer and is set to block on queue reads. The queue
* only has space for one item - as soon as the producer posts a message on the
* queue the consumer will unblock, pre-empt the producer, and remove the item.
*
* The second two tasks work the other way around. Again the queue used only has
* enough space for one item. This time the consumer has a lower priority than the
* producer. The producer will try to post on the queue blocking when the queue is
* full. When the consumer wakes it will remove the item from the queue, causing
* the producer to unblock, pre-empt the consumer, and immediately re-fill the
* queue.
*
* The last two tasks use the same queue producer and consumer functions. This time the queue has
* enough space for lots of items and the tasks operate at the same priority. The
* producer will execute, placing items into the queue. The consumer will start
* executing when either the queue becomes full (causing the producer to block) or
* a context switch occurs (tasks of the same priority will time slice).

* This is a version of PollQ.c that uses the alternative (Alt) API.
*
* Creates two tasks that communicate over a single queue. One task acts as a
* producer, the other a consumer.
*
* The producer loops for three iteration, posting an incrementing number onto the
* queue each cycle. It then delays for a fixed period before doing exactly the
* same again.
*
* The consumer loops emptying the queue. Each item removed from the queue is
* checked to ensure it contains the expected value. When the queue is empty it
* blocks for a fixed period, then does the same again.
*
* All queue access is performed without blocking. The consumer completely empties
* the queue each time it runs so the producer should never find the queue full.
*
* An error is flagged if the consumer obtains an unexpected value or the producer
* find the queue is full.
