Crate ds3502 

I2C Digitial Potentiometer DS3502 driver in Rust

Rust embedded driver for the DS3502 Digital Potentiometer by Analog Devices Inc./Maxim Integrated. Supports block and async APIs.

Usage

use ds3502::{Ds3502, Wiper, ControlRegisterMode};
let mut digipot = Ds3502::blocking_init(i2c, Default::default())?;

// By default, driver initialized with Control Register in Mode 1 (Don't save to EEPROM)
assert_eq!(digipot.mode(), ControlRegisterMode::WiperOnly);

let wv = Wiper::try_from(88)?;
digipot.write_wiper(wv)?;

// Set wiper value and save to EEPROM
let wv = Wiper::try_from(123)?;
digipot.write_and_save_wiper(wv);

For a complete example that builds and flashes to a Raspberry Pi Pico using the embassy framework, checkout the pico-example directory.
