Downloadable macro reference
ReadProximityByte
Get the current proximity reading as a digital value from 0 to 255.
The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
Parameters
- This macro has no parameters
Return value
ReadProximityFloat
Get the current proximity as an analogue value from 0.0 to 1.0.
The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
Parameters
- This macro has no parameters
Return value
ReadProximityInt
Get the current proximity as a digital value, 10 bit or 12 bit based on your ADC capabilities.
The 'Polarity' property will affect whether the signal increases or decreases as the proximity increases.
Parameters
- This macro has no parameters
Return 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
Analog Pin
This property is of type Single analog pin and can be referenced with the variable name AnPin.
No additional information
Polarity
This property is of type Fixed list of ints and can be referenced with the variable name polarity.
The 'Polarity' property will affect whether the signal increases of decreases as the proximity increases.
Rising - Increases signal as proximity increases
Falling - Decreases signal as proximity increases
VRef voltage
This property is of type Signed integer and can be referenced with the variable name adc_base1::vrefvol.
Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage.
+VRef voltage x 10mV
Default 500 = 5.0V
VRef option
This property is of type Fixed list of ints and can be referenced with the variable name adc_base1::vrefop.
Defines what is used as the ADC maximum reference. ADC Range = GND to VRef Voltage
VDD - Defines the microcontrollers power supply pin as the max reference,
VREF+ Pin - Dedicated pin on the microcontroller to allow for a variable reference voltage.
Conversion speed
This property is of type Fixed list of ints and can be referenced with the variable name adc_base1::convspd.
Clock setting to select how fast the ADC peripheral will perform an ADC conversion.
The FRC setting is based on a RC time base and so will vary with temperature and pressure.
Other settings are generally based on divisions of the master clock.
Acquisition cycles
This property is of type Signed integer and can be referenced with the variable name adc_base1::actime.
Number of micro seconds to wait for the ADC input to charge before starting the analogue sample.
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 sensor begins to be activated.
NB) This is measured between the centre of the proximity sensor 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.
Scope Traces
This property is of type True or false and can be referenced with the variable name adc_base1::ScopeTraces.
Selects if the scope traces are automatically generated or not
