/** \defgroup Group_Scheduler Simple Task Scheduler - LUFA/Scheduler/Scheduler.h
* \brief Simple round-robbin pseudo-task scheduler.
*
* \deprecated This module is deprecated and will be removed in a future library release.
*
* \section Sec_Dependencies Module Source Dependencies
* The following files must be built with any user project that uses this module:
* - LUFA/Scheduler/Scheduler.c <i>(Makefile source module name: LUFA_SRC_SCHEDULER)</i>
*
* \section Sec_ModDescription Module Description
* Simple round-robbin cooperative scheduler for use in basic projects where non real-time tasks need
* to be executed. Each task is executed in sequence, and can be enabled or disabled individually or as a group.
*
* For a task to yield it must \c return, thus each task should have persistent data marked with the \c static keyword.
*
* Each LUFA scheduler task should be written similar to an ISR; it should execute quickly (so that no one task
* hogs the processor, preventing another from running before some sort of timeout is exceeded). Unlike normal RTOS
* tasks, each LUFA scheduler task is a regular function, and thus must be designed to be called, and designed to
* return to the calling scheduler function repeatedly. Data which must be preserved between task calls should be
* declared as global or (preferably) as a \c static local variable inside the task.
*
* The scheduler consists of a task list, listing all the tasks which can be executed by the scheduler. Once started,
* each task is then called one after another, unless the task is stopped by another running task or interrupt.
*
* Usage Example:
* \code
* #include <LUFA/Scheduler/Scheduler.h>
*
* TASK(MyTask1); // Task prototype
* TASK(MyTask2); // Task prototype
*
* TASK_LIST
* {
* { .Task = MyTask1, .TaskStatus = TASK_RUN, .GroupID = 1 },
* { .Task = MyTask2, .TaskStatus = TASK_RUN, .GroupID = 1 },
* }
*
* int main(void)
* {
* Scheduler_Init();
*
* // Other initialisation here
*
* Scheduler_Start();
* }
*
* TASK(MyTask1)
* {
* // Task implementation here
* }
*
* TASK(MyTask2)
* {
* // Task implementation here
* }
* \endcode
*
* If desired, the LUFA scheduler <b>does not need to be used</b> in a LUFA powered application. A more conventional
* approach to application design can be used, or a proper scheduling RTOS inserted in the place of the LUFA scheduler.
* In the case of the former the USB task must be run manually repeatedly to maintain USB communications, and in the
* case of the latter a proper RTOS task must be set up to do the same.
