Property reference

	Properties
	Device (Bidirectional)
	VDD
	Channel
Analogue Input Channel - Which pin is the analogue input connected to?
	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.
	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
	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.
	Connections
	Simulations
