	Convert a voltage to a 12-bit ADC count.

Detailed Description

Lightweight utility functions for engineering-unit conversion.

Function Documentation

VoltageToCount()

constexpr uint16_t ads7952::VoltageToCount ( float  voltage, float  vref  )

constexprnoexcept

Convert a voltage to a 12-bit ADC count.

Useful for computing alarm thresholds from engineering units. The result is clamped to 0–4095.

Parameters

voltage	Target voltage in volts
vref	Reference voltage in volts

Returns

uint16_t 12-bit ADC count

uint16_t low  = ads7952::VoltageToCount(0.5f, 2.5f);  // → 819
uint16_t high = ads7952::VoltageToCount(2.0f, 2.5f);  // → 3276
adc.ProgramAlarm(0, ads7952::AlarmBound::Low, low);
