Properties |
|
VRef voltage |
| Used by the GetVoltage or GetString component macros to take an ADC reading and convert it into a Voltage. +VRef voltage x 10mV Default 500 = 5.0V | |
|
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. | |
|
|
Aquisition cycles |
| Number of micro seconds to wait for the ACD input to charge before starting the analogue sample. | |
|
|
Bit Depth |
| Maximum number of digital bits the ADC can sample. 8 bit = ADC range 0 - 255 10 bit = ADC range 0 - 1023 12 bit = ADC range 0 - 4095 | |
|
Connections |
|
Channel |
| Analogue input channel - which pin is the analogue input conected to? | |
|
|
Simulations |
|
Tang Color |
| Colour of the moving part of the slider. | |
|
|
Marker Color |
| Colour of the marker line across the slider tang. | |
|
Scope Traces |
| Selects if the scope traces are automatically generated or not | |
