ReadState
Get the current collision state.
The 'Polarity' property will affect whether a collision is represented by a high
or low state.
Parameters
- This macro has no parameters
Return value
WaitUntilHigh
Pause the program until the detector goes high.
'Polarity' will affect whether high value represents a collision or separation.
NB) In simulation, only use this macro if testing for collision with animated or
timer driven objects!!
Parameters
- This macro has no parameters
Return value
- This call does not return a value
WaitUntilLow
Pause the program until the detector goes low.
'Polarity' will affect whether low value represents a collision or separation.
NB) In simulation, only use this macro if testing for collision with animated or
timer driven objects!!
Parameters
- This macro has no parameters
Return value
- This call does not return a value
Simulation macro reference
SetTarget
Set the object that you want to test for collision with.
If this is not called, or is called with handle = 0, collisions will be tested against
every panel object that has 'Solid' status.
NB) Specifying an object will save CPU power!!
Parameters
- HANDLE Target
- The object to test for collision with.
Return value
- This call does not return a value
Property reference
Pin
This property is of type Single digital pin and can be referenced with the variable name pin.
The chip pin that will receive the switch status.
Polarity
This property is of type Fixed list of ints and can be referenced with the variable name polarity.
Select the pin state that will indicate that an object has been detected.
Magnet Object
This property is of type Panel object and can be referenced with the variable name target.
Select an object from the panel to act as the magnet that triggers the reed switch.
Range
This property is of type Floating point and can be referenced with the variable name range.
Distance within which the switch is activated.
NB) This is measured between the centre of the proximity switch and the centre of the target object.
Timer Interval (ms)
This property is of type Unsigned integer and can be referenced with the variable name timer_int.
Time in milliseconds between testing for proximity.
Small time = Greater CPU load
Large time = More like to miss activation if it is very brief.
