|
||||
* (the queue receive task) blocks on the queue to wait for data to arrive,
|
||||
* toggling an LED each time '100' is received. The other task (the queue send
|

* task) repeatedly blocks for a fixed period before sending '100' to the queue
|
||||
* (causing the first task to toggle the LED).

* For a much more complete and complex example select either the Debug or
|

* Debug_with_optimisation build configurations within the HEW IDE.
