4:c449bead5cf3 | 15 | * \section Libary-Event-API Library Event API |
| Mika Karjalainen |
4:c449bead5cf3 | 16 | * - event_dispatch(), NanoStack 2.x event dispatcher loop call |
| Mika Karjalainen |
4:c449bead5cf3 | 17 | * - arm_ns_event_send(), Event send function |
| Mika Karjalainen |

4:c449bead5cf3 | 19 | * \section Global-Interrupts-API Global Interrupts API |
| Mika Karjalainen |
4:c449bead5cf3 | 20 | * - lib_enter_critical(), Disable Interrupt |
| Mika Karjalainen |
4:c449bead5cf3 | 21 | * - lib_exit_critical(), Enable Interrupt |
| Mika Karjalainen |
4:c449bead5cf3 | 22 | * Application can handle global interrupts by using next two macros. |
| Mika Karjalainen |
4:c449bead5cf3 | 23 | * These are mandatory if interrupt uses event_send() function. |

| Mika Karjalainen |
4:c449bead5cf3 | 25 | * \section Library-Timer-API Library Timer API |
| Mika Karjalainen |
4:c449bead5cf3 | 26 | * - timer_sys_event(), Used to allocate timer events |
| Mika Karjalainen |
4:c449bead5cf3 | 27 | * - timer_sys_event_cancel(), Used to cancel allocated timer events |
| Mika Karjalainen |
4:c449bead5cf3 | 28 | * |
| Mika Karjalainen |
4:c449bead5cf3 | 29 | * If the application needs any timers it can allocate one with timer_sys_event() function. |
| Mika Karjalainen |
4:c449bead5cf3 | 30 | * After the needed timers are allocated system timer event occurs. |
| Mika Karjalainen |
4:c449bead5cf3 | 31 | * |
| Mika Karjalainen |
4:c449bead5cf3 | 32 | * Note: Library supports 6 concurrent timers for the application layer use. Quite often the application can multiplex a single timer for multiple purposes. |
| Mika Karjalainen |
4:c449bead5cf3 | 33 | * Library timer API is not mandatory to be used if own timer drivers are desired. |

4:c449bead5cf3 | 37 | * NanoStack2.0 Library works in event-based scheduling model. This chapter describes the event functionality on the application level. |
| Mika Karjalainen |
4:c449bead5cf3 | 38 | * All events are handled in tasklet_main() function and therefore the main.c file must contain this function. The main event senders are SYSTEM, SYSTEM_TIMER, TL_DNSSD, APP_SPESIFIC_EVENT and EV_NETWORK. See below for example of a tasklet_main(). |
