Property reference
|
Properties |
|
ADC Configuration |
|
ADC Channel |
| Analogue Input Channel - Which pin is the analogue input connected to? | |
|
|
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 | |
