MCP3424

This crate provides an async Rust driver for the MCP342[2/3/4] ADC, based on the embedded-hal traits.

The MCP3422, MCP3423 and MCP3424 are low-noise, high accuracy delta-sigma A/D converter with differential inputs, on-board precision 2.048V reference voltage and up to 18 bits of resolution. The devices offer a two-wire I2C compatible serial interface.

Status

• One-Shot conversions.
• Continuous conversions.
• Configuration:
  • Programmable gain amplifier (PGA)
  • Resolution / Sample Rate
  • Channel
• Async API
  • Future based
  • Stream based (optional)
• Defmt integration (optional)
• UOM integration (optional)

Appetizer

Trigger a one-shot conversion and awaits the result:

use mcp3424::{MCP3424, Configuration, OneShotMode};

let mut adc = MCP3424::new(i2c, 0x68, Delay, OneShotMode::new(&Configuration::default()));

match adc.measure().await {
    Ok(value) => println!("Measured value: {:?}", value),
    Err(_) => println!("Failed to measure"),
}
