Macro reference

GetString

	GetString
Reads the ADC as a direct voltage and returns as as tring
- STRING	Return

GetAverageByte

	GetAverageByte
Function call to read the ADC as a byte average sample over time
- BYTE	NumSamples
- BYTE	DelayUs
Number of micro seconds in between taking each sample
- BYTE	Return

GetAverageInt

	GetAverageInt
Function call to read the ADC as a full width average sample over time
- BYTE	NumSamples
- BYTE	DelayUs
Number of micro seconds in between taking each sample
- UINT	Return

Property reference

	Properties
	Simulation
	Scope Traces
Selects if the scope traces are automatically generated or not
	Connections
	Channel
Analogue input channel - which pin is the analogue input conected to?
	Settings
	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.
	Aquisition cycles
Number of micro seconds to wait for the ACD input to charge before starting the analogue sample.
	Bit Depth
Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095
