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
GetRealTemperature
Reads the ADC input and Returns the calculated Temperature as Float value in degrees C
Parameters
- This macro has no parameters
Return value
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
GetADCValue
Returns the Raw ADC value from the Analogue Channel
Parameters
- This macro has no parameters
Return value
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.
