/**
|
||||
* \defgroup timer Timer library
|
||||
*
|
||||
* The timer library provides functions for setting, resetting and
|
||||
* restarting timers, and for checking if a timer has expired. An
|
||||
* application must "manually" check if its timers have expired; this
|
||||
* is not done automatically.
|
||||
*
|
||||
* A timer is declared as a \c struct \c timer and all access to the
|
||||
* timer is made by a pointer to the declared timer.
|
||||
*
|
||||
* \note The timer library uses the \ref clock "Clock library" to
|
||||
* measure time. Intervals should be specified in the format used by
|
||||
* the clock library.
