ADS124S08 Embassy Driver

Embassy-based driver for the Texas Instruments ADS124S08 24-bit precision ADC. This driver provides async support for SPI communication with the ADS124S08, suitable for high-precision analog-to-digital conversion in espresso machine temperature and pressure sensing applications.

The ADS124S08 is a precision, 24-bit, analog-to-digital converter (ADC) with 12 single-ended or 6 differential inputs, programmable gain amplifier (PGA), voltage reference, and two excitation current sources (IDACs).

Usage Example

use variegated_ads124s08::{ADS124S08, WaitStrategy, PGAGain, ReferenceInput, IDACMagnitude, IDACMux};
 
// Create the driver with SPI device, DRDY pin, and delay provider
let wait_strategy = WaitStrategy::UseDrdyPin(drdy_pin);
let mut adc = ADS124S08::new(spi_device, wait_strategy, delay);

// Initialize the device
adc.initialize().await?;

// Perform a high-level measurement 
let result = adc.measure_input_with_reference_and_pga(
    InputP::AIN0,      // Positive input
    InputN::AIN1,      // Negative input  
    ReferenceInput::REF0P_REF0N,  // Reference
    PGAGain::GAIN16,   // 16x gain
    Some(IDACMagnitude::uA500),   // 500µA excitation current
    IDACMux::AIN0,     // Current output to AIN0
).await?;

// Convert to voltage
let voltage = result.to_voltage();
