Example showing how to build a component using a CAL component Using CAL Components.

Macro reference

Disable

	Disable
Disables the current ADC channel Call this once sampling is complete
- VOID	Return

Enable

	Enable
Enables sampling of the ADC channel This is called every time a new ADC channel needs configuring to ADC mode [u]Only one ADC channel may be enabled at any time[/u] When sampling is complete, call Disable() to restore the pin
- BYTE	Channel
A value >= 0 specifying the ADC channel
- BYTE	Conv_Speed
Chip-specific rate of change read from the FCD <ADC.ConfSpeed>
- BYTE	Vref
0 to disable Vref mode, else 1
- BYTE	T_Charge
Aquisition time to wait in micro seconds
- VOID	Return

GetList

	GetList

- STRING	Name

- STRING	Return

GetValue

	GetValue
Gets the Name property value
- STRING	Name
The name of the property
- STRING	Return

Sample

	Sample
Blocking call to read a sample on the currently enabled channel
- BYTE	Sample_Mode
True to enable full-width sample (10 or 12 bits), else false for 8 bit
- UINT	Return

SetValue

	SetValue
Sets the Value for the named property
- STRING	Name
Name of property to update
- STRING	Value
The new value for the property
- VOID	Return

Property reference

	Properties
	Peripheral

	Channel ADC Pin
ADC Channel number
	Vref Option
selects the reference voltage option
	Vref+ (x10mV)
sets the value of the reference voltage (used for conversion calculations)
	Acq Time
ADC Aquisition time
	Use FRC clock
Uses the internal fixed RC clock to perform ADC conversions. In most cases it is better to switch this off and use the conversion speed to ensure sampling is consistent.
	Conv Speed
Conversion speed option
	Type

	Bits

	Custom Pins

	Has DMA

	Use DMA

	DMA Trigger

	Has Scanning

	Use Scanning

	Simulation
	Scope Traces
Selects if the scope traces are automatically generated or not
