Module esp32s3_hal::adc

Expand description

Analog to digital (ADC) conversion support.

Overview

The ADC module in the analog driver enables users to perform analog-to-digital conversions, allowing them to measure real-world analog signals with high accuracy.

This module provides functions for reading analog values from the analog to digital converter available on the ESP32-S3: ADC1 and ADC2.

Example

ADC on Xtensa architecture
// Create ADC instances
let analog = peripherals.SENS.split();

let mut adc1_config = AdcConfig::new();

let mut pin3 =
    adc1_config.enable_pin(io.pins.gpio3.into_analog(), Attenuation::Attenuation11dB);

let mut adc1 = ADC::<ADC1>::adc(analog.adc1, adc1_config).unwrap();

let mut delay = Delay::new(&clocks);

loop {
    let pin3_value: u16 = nb::block!(adc1.read(&mut pin3)).unwrap();
    println!("PIN3 ADC reading = {}", pin3_value);
    delay.delay_ms(1500u32);
}
