bogdanm 0:eff01767de02 18 *
bogdanm 0:eff01767de02 19 * @brief Application timer functionality.
bogdanm 0:eff01767de02 20 *
bogdanm 0:eff01767de02 21 * @details It enables the application to create multiple timer instances based on the RTC1
bogdanm 0:eff01767de02 22 * peripheral. Checking for timeouts and invokation of user timeout handlers is performed
bogdanm 0:eff01767de02 23 * in the RTC1 interrupt handler. List handling is done using a software interrupt (SWI0).
bogdanm 0:eff01767de02 24 * Both interrupt handlers are running in APP_LOW priority level.
bogdanm 0:eff01767de02 25 *
bogdanm 0:eff01767de02 26 * @note When calling app_timer_start() or app_timer_stop(), the timer operation is just queued,
bogdanm 0:eff01767de02 27 * and the software interrupt is triggered. The actual timer start/stop operation is
bogdanm 0:eff01767de02 28 * executed by the SWI0 interrupt handler. Since the SWI0 interrupt is running in APP_LOW,
bogdanm 0:eff01767de02 29 * if the application code calling the timer function is running in APP_LOW or APP_HIGH,
bogdanm 0:eff01767de02 30 * the timer operation will not be performed until the application handler has returned.
bogdanm 0:eff01767de02 31 * This will be the case e.g. when stopping a timer from a timeout handler when not using
bogdanm 0:eff01767de02 32 * the scheduler.
bogdanm 0:eff01767de02 33 *
bogdanm 0:eff01767de02 34 * @details Use the USE_SCHEDULER parameter of the APP_TIMER_INIT() macro to select if the
bogdanm 0:eff01767de02 35 * @ref app_scheduler is to be used or not.
bogdanm 0:eff01767de02 36 *
bogdanm 0:eff01767de02 37 * @note Even if the scheduler is not used, app_timer.h will include app_scheduler.h, so when
bogdanm 0:eff01767de02 38 * compiling, app_scheduler.h must be available in one of the compiler include paths.
