InterruptSourceNumberGet()

int32_t InterruptSourceNumberGet ( )

inherited

Description:

InterruptSourceNumberGet returns the number of the object (Axis, Motor, etc) that generated the interrupt.

Returns

(int32_t) Index or number of the object that generated the interrupt.

Note

For UserLimit objects, RapidCode internally uses one UserLimit per Axis. To determine which UserLimit triggered, you must subtract the AxisCount.

int32_t triggeredUserLimit  = controller.InterruptSourceNumberGet()-AXIS_COUNT;

Examples

ControllerInterrupts.cpp, and UserLimit.cs.
