Jonathan Austin 1:8aa5cdb4ab67 80 * Class definition for MicroBitComponent.
Jonathan Austin 1:8aa5cdb4ab67 81 *
Jonathan Austin 1:8aa5cdb4ab67 82 * All components should inherit from this class.
Jonathan Austin 1:8aa5cdb4ab67 83 *
LancasterUniversity 41:da05ec75cd5d 84 * If a component requires regular updates, then that component can be added to the
LancasterUniversity 41:da05ec75cd5d 85 * to the systemTick and/or idleTick queues. This provides a simple, extensible mechanism
LancasterUniversity 41:da05ec75cd5d 86 * for code that requires periodic/occasional background processing but does not warrant
LancasterUniversity 41:da05ec75cd5d 87 * the complexity of maintaining its own thread.
LancasterUniversity 41:da05ec75cd5d 88 *
LancasterUniversity 41:da05ec75cd5d 89 * Two levels of support are available.
Jonathan Austin 1:8aa5cdb4ab67 90 *
LancasterUniversity 41:da05ec75cd5d 91 * systemTick() provides a periodic callback during the
LancasterUniversity 41:da05ec75cd5d 92 * micro:bit's system timer interrupt. This provides a guaranteed periodic callback, but in interrupt context
LancasterUniversity 41:da05ec75cd5d 93 * and is suitable for code with lightweight processing requirements, but strict time constraints.
LancasterUniversity 41:da05ec75cd5d 94 *
LancasterUniversity 41:da05ec75cd5d 95 * idleTick() provides a periodic callback whenever the scheduler is idle. This provides occasional, callbacks
LancasterUniversity 41:da05ec75cd5d 96 * in the main thread context, but with no guarantees of frequency. This is suitable for non-urgent background tasks.
Jonathan Austin 1:8aa5cdb4ab67 97 *
LancasterUniversity 41:da05ec75cd5d 98 * Components wishing to use these facilities should override the systemTick and/or idleTick functions defined here, and
LancasterUniversity 41:da05ec75cd5d 99 * register their components using system_timer_add_component() fiber_add_idle_component() respectively.
LancasterUniversity 41:da05ec75cd5d 100 *
