Programmable pulse generation
Events are functions called when some important event occurred and its processing starts.
|
Events:
-
EventModule
- Name of the user module (without extension), where the events from this bean 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 bean (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 bean (more than one speed mode).
ANSIC prototype: void AfterNewSpeed(void)
-
OnEnd
- This event is called when the specified number of iterations is generated. (Only when the bean is enabled - Enable and the events are enabled - EnableEvent).
ANSIC prototype: void OnEnd(void)
- Priority - OnEnd priority Default value is based on the interrupt priority defined in property Interrupt priority. For details see description below of the page.
- Events for some Freescale HCS12/HCS12X derivatives.
-
OnShutdown
- This event is called when the PWM emergency shutdown is asserted and de-asserted.
The method GetShutdownStatus can be used to get current status of the input pin.
The method RestartPWM can be used to restart PWM generation after emergency shutdown is de-asserted.
Event is available only when the Emergency interrupt service/event is enabled.
ANSIC prototype: void OnShutdown(void)
- Priority - Priority of the event routine. For details see description below of the page.
For each generated event it is possible to set:
