Property reference
|
Properties |
|
Connections |
|
Analog Pin |
|
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 | |
|
|
ADC Properties |
|
VRef voltage |
| 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 |
| 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 |
| 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 |
| Number of micro seconds to wait for the ADC input to charge before starting the analogue sample. | |
|
|
Simulation |
|
Magnet Object |
| Select an object from the panel to act as the magnet that triggers the reed switch. | |
|
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) |
| 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 |
| Selects if the scope traces are automatically generated or not | |
