Examples

Macro reference

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

GetByte

	GetByte
Blocking call to read the ADC as a byte
- BYTE	Return

GetInt

	GetInt
Blocking call to read the ADC at full bit depth
- UINT	Return

GetSampleBits

	GetSampleBits
Gets the number of bits per sample
- BYTE	Return

GetSpeedFilter

	GetSpeedFilter
Gets the Conversion speed filter string Use in Component.Property.SetFilter()
- STRING	Return

GetString

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

GetVoltage

	GetVoltage
Reads the ADC as a direct voltage
- FLOAT	Return

RawAverageByte

	RawAverageByte
Background call to read the ADC as a byte average sample over time Call Enable() before this
- BYTE	NumSamples

- BYTE	DelayUs
Number of micro seconds in between taking each sample
- BYTE	Return

RawAverageInt

	RawAverageInt
Background call to read the ADC as a full width average sample over time Call Enable() before this
- BYTE	NumSamples

- BYTE	DelayUs

- INT	Return

RawDisable

	RawDisable
Disables the previously enabled ADC channel and converts back to digital mode.
- VOID	Return

RawEnable

	RawEnable
Enables and configures the ADC channel to be an analogue input. Only one ADC channel can be enabled at a time. Any RAW functions will reference the last enabled channel only.
- VOID	Return

RawSampleByte

	RawSampleByte
Background call to read the ADC as a byte Call Enable() before this
- BYTE	Return

RawSampleInt

	RawSampleInt
Background call to read the ADC at full bit depth Call Enable() first
- UINT	Return

SetChannel

	SetChannel
Sets the channel ID for the component
- INT	ChannelId
Chaannel starting at 0, -1 is unconnected
- VOID	Return

SetProperties

	SetProperties
Set the VRef options and voltage, ConvSpeed and AcqTime for the ADC component.
- INT	VRef10Ms
Voltage Reference x10 mV - Default 500 = 5V
- BOOL	VRefOpt
External VRef 0=Disabled, 1=Enabled
- INT	ConvSpdOpt
Conversion Speed Setting - Refer to numbered list
- INT	Aquisitions
Aquisition time in micro seconds to precharge before sampling
- VOID	Return

Property reference

	Properties
	Connections
	Channel
Analogue Input Channel - Which pin is the analogue input connected 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.
	Acquisition cycles
Number of micro seconds to wait for the ADC 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
	Simulation
	Scope Traces
Selects if the scope traces are automatically generated or not
