Component FreeCntr
Time measurement based on counter value (suitable for short time periods)
Component Level: Low
Category: CPU Internal Peripherals-Timer
Events:
(Events are call-back functions called when an important event occurrs. Please see the Embedded Components page for more information.)
  • EventModule - Name of the user module (without extension), where the events from this component are placed.
  • BeforeNewSpeed - This event is called when the CPU speed mode is being changed (using CPU methods) - before the change. The event is enabled only if speed modes are supported in the target CPU component (more than one speed mode).

      ANSIC prototype: void BeforeNewSpeed(void)

  • AfterNewSpeed - This event is called when the CPU speed mode is being changed (using CPU methods) - after the change. The event is enabled only if speed modes are supported in the target CPU component (more than one speed mode).

      ANSIC prototype: void AfterNewSpeed(void)

  • OnInterrupt - This event is called when a compare matches the counter value (if compare or reload is selected as a interrupt source) or a counter overflows (for free-running devices). It is valid only when the component is enabled - "Enable" and the events are enabled - "EnableEvent". The event is available only if Interrupt service/event is enabled.

      ANSIC prototype: void OnInterrupt(void)
    • Priority - OnOverflow priority. Default value is based on the interrupt priority defined in property Interrupt priority. For details see description below of the page.

For each generated event it is possible to set:
