Unlike a conventional, complex RTOS scheduler, the * LUFA scheduler is very simple in design and operation and is essentially a loop conditionally executing a series * of functions. * * 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 (prefferably) as a 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. * * * If desired, the LUFA scheduler does not need to be used 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. * * * For more information on the LUFA scheduler, see the Scheduler.h file documentation. */
