Thermistor Template component

Base component for creating thermistors. Has no GUI - this would be added by concrete examples using this basem which may or may not expose the propertes.

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

Downloadable macro reference

GetIntegerTemperature

Reads the ADC input and returns the calculated Temperature as Integer degrees C

Parameters

This macro has no parameters

Return value

INT

GetRealTemperature

Reads the ADC input and Returns the calculated Temperature as Float value in degrees C

Parameters

This macro has no parameters

Return value

FLOAT

CalculateTemperature

Converts the input ADC value and returns the Temperature in tenths of degree C

Parameters

UINT ADCValue

ADC Reading to be converted

Return value

INT

GetADCValue

Returns the Raw ADC value from the Analogue Channel

Parameters

This macro has no parameters

Return value

UINT

Simulation macro reference

SetChannel

Set the ADC Channel

Parameters

INT ChannelID

Return value

This call does not return a value

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.

Parameters

FLOAT Temperature

The temperature in C - restricted to -25 to +125 range

Return value

This call does not return a value

Property reference

ADC Channel

This property is of type Single analog pin and can be referenced with the variable name CHANNEL.

The ADC channel to which the thermistor circuit is connected.

It is assumed that the thermistor is connected between the ADC pin and 0V, with a fixed resistor connected

between the ADC pin and +V.

Wiring

This property is of type Fixed list of ints and can be referenced with the variable name 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.

ADC Bit Resolution

This property is of type Unsigned integer and can be referenced with the variable name ADC_BITS.

No additional information

Resistor Value

This property is of type Unsigned integer and can be referenced with the variable name RESISTOR.

Value in Ohms of the pullup series resistor. i.e. The resistor is connected between the ADC pin and the

positive supply rail.
