Thermistor component
A generic thermistor component that can be used to simulate and create code for any thermistor with a known temperature/resistance curve. Thermistor is connected in a simple potential divider circuit - thermistor between ADC input and 0V, and a fixed resistor between ADC and the positive supply. Default calibration is for the EBM003 module.

ADC Properties |
|
ADC 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. | |
|
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. | |
|
ADC Bit Resolution |
|
|
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. | |
|
|
