typedef struct _NUTTIMERINFO NUTTIMERINFO

Timer type.

Variable Documentation

NUTTIMERINFO* volatile nutTimerList (    )

Linked list of all system timers.

NUTTIMERINFO* volatile nutTimerPool (    )

This pool is used to collect released memory from elapsed timers. It's required because we can't free memory in interrupt context.
