Detailed Description

Class to manage ADC hardware sampling and filtering.

Constructor & Destructor Documentation

inline

Constructor.

Parameters

adc_cap	Pointer to ADC for capacitor-side sampling
adc_bat	Pointer to ADC for battery-side sampling
adc_temp	Pointer to ADC for temperature sensing

HAL_StatusTypeDef adc_manager::adc_init ( uint8_t * filters_length )

Initializes ADCs and filter states.

Initializes ADC peripherals, DMA, and filter buffers.

Parameters

filters_length Pointer to array of filter lengths per channel

Also starts internal ADC calibration and begins temperature ADC readings.

Parameters

filters_length Pointer to an array specifying the filter window length per channel.

float adc_manager::get_temperature ( )

Reads temperature using onboard NTC.

Calculates the ambient temperature using a thermistor connected to an analog input.

Converts ADC reading to voltage, calculates NTC resistance, and applies the B-parameter equation.

bool adc_manager::calibration_ready = false

Optional flag for calibration flow.
