This voltage input allows the conversion of an analog
voltage into a digital value. Voltage inputs are useful for many circuits
including sensors with analog outputs and measuring supply voltages.
Hardware Interface: The PSoC pin
is a high impedance analog input connection to the Analog to Digital Converter
(ADC). The input voltage is scaled through a voltage divider to the native PSoC
voltage precision reference range (0-2600 mV).
Software Interface: 16-bit signed
integer, stored most significant byte first, contains the converted voltage in
whole number format to 1mV resolution (example: 2.123VDC stored as 2123).
This driver has no user-configurable properties.
