Examples

This example simply reads the value from the thermistor sensor component and outputs the value to an LCD as a temperature in degrees C. EBM003 Example

Macro reference

CalculateTemperature

	CalculateTemperature
Converts the input ADC value and returns the Temperature in tenths of degree C
- UINT	ADCValue
ADC Reading to be converted
- INT	Return

GetADCValue

	GetADCValue
Returns the Raw ADC value from the Analogue Channel
- UINT	Return

GetIntegerTemperature

	GetIntegerTemperature

	SetChannel
Set the ADC Channel
- INT	ChannelID

- VOID	Return

SetTemperature

	SetTemperature
Simulation macro that sets the internal ADC value to the appropriate value for a given temperature. This allows all internal systems of the sensor to be simulated.

Property reference

	Properties
	ADC Channel
Analogue Input Channel - Which pin is the analogue input connected to?
	ADC Bit Resolution

	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.
	Wiring
Specifies the arrangement of the Thermistor and Fixed Resistor. Pull Down - Thermistor connected between ADC pin and GND, fixed resistor between ADC pin and VCC. Pull Up - Thermistor connected between ADC pin and VCC, fixed resistor between ADC pin and GND.
	Resistor Value
Value in Ohms of the pullup series resistor. i.e. The resistor is connected between the ADC pin and the positive supply rail.
	-25C Thermistor Value
Value in Ohms of the Thermistor at -25 deg C
	0C Thermistor Value
Value in Ohms of the Thermistor at 0 deg C
	25C Thermistor Value
Value in Ohms of the Thermistor at 25 deg C
	50C Thermistor Value
Value in Ohms of the Thermistor at 50 deg C
	75C Thermistor Value
Value in Ohms of the Thermistor at 75 deg C
	100C Thermistor Value
Value in Ohms of the Thermistor at 100 deg C
	125C Thermistor Value
Value in Ohms of the Thermistor at 125 deg C
