bool idfxx::adc::sampler::config::operator== ( const config & ) const

defaultnoexcept

Compares two configurations for equality.

enum attenuation idfxx::adc::sampler::config::attenuation = attenuation::db_12

Input range selection, applied uniformly to all pins (hardware limitation).

Definition at line 244 of file adc.hpp.

size_t idfxx::adc::sampler::config::buffer_samples = 1024

Internal pool capacity in samples (at least frame_samples). Reads must drain the pool faster than it fills or data is dropped (see overruns).

Definition at line 252 of file adc.hpp.

size_t idfxx::adc::sampler::config::frame_samples = 256

Samples delivered per driver transfer — the read granularity.

Definition at line 249 of file adc.hpp.

std::vector<idfxx::gpio> idfxx::adc::sampler::config::pins {}

ADC1-capable GPIOs, converted round-robin in this order (required, no duplicates).

Definition at line 242 of file adc.hpp.

freq::hertz idfxx::adc::sampler::config::sample_rate {20'000}

Total conversion rate across all pins; each pin samples at this rate divided by the pin count.

Valid range is chip-specific; 20 kHz works on every target.
