| #define APP_TIMER_CONFIG_IRQ_PRIORITY |
Interrupt priority.
Priorities 0,2 (nRF51) and 0,1,4,5 (nRF52) are reserved for SoftDevice
Following options are available:
| #define APP_TIMER_CONFIG_OP_QUEUE_SIZE |
Capacity of timer requests queue.
Size of the queue depends on how many timers are used in the system, how often timers are started and overall system latency. If queue size is too small app_timer calls will fail.
| #define APP_TIMER_CONFIG_RTC_FREQUENCY |
Configure RTC prescaler.
Following options are available:
| #define APP_TIMER_CONFIG_SWI_NUMBER |
Configure SWI instance used.
Set to 1 to activate.
| #define APP_TIMER_CONFIG_USE_SCHEDULER |
Enable scheduling app_timer events to app_scheduler.
Set to 1 to activate.
| #define APP_TIMER_ENABLED |
Enabling app_timer module.
Set to 1 to activate.
| #define APP_TIMER_KEEPS_RTC_ACTIVE |
Enable RTC always on.
If option is enabled RTC is kept running even if there is no active timers. This option can be used when app_timer is used for timestamping.
Set to 1 to activate.
| #define APP_TIMER_SAFE_WINDOW_MS |
Maximum possible latency (in milliseconds) of handling app_timer event.
Maximum possible timeout that can be set is reduced by safe window. Example: RTC frequency 16384 Hz, maximum possible timeout 1024 seconds - APP_TIMER_SAFE_WINDOW_MS. Since RTC is not stopped when processor is halted in debugging session, this value must cover it if debugging is needed. It is possible to halt processor for APP_TIMER_SAFE_WINDOW_MS without corrupting app_timer behavior.
| #define APP_TIMER_WITH_PROFILER |
Enable app_timer profiling.
Set to 1 to activate.
