Crate bq25887 

BQ25887 battery charger driver

bq25887 is a platform-agnostic Rust driver for the Texas Instruments BQ25887 synchronous battery charger. It targets no_std environments and provides an async-friendly I²C interface built on the embedded-hal-async traits.

The optional embassy feature supplies helpers for constructing shared-bus drivers that integrate smoothly with the Embassy async ecosystem.

Examples

Create a driver with an async I²C peripheral and read the charger status:

use bq25887::Bq25887Driver;

async fn inspect<I2C>(i2c: I2C) -> Result<(), bq25887::BQ25887Error<I2C::Error>>
where
    I2C: embedded_hal_async::i2c::I2c,
{
    let mut driver = Bq25887Driver::new(i2c);
    let status = driver.read_charger_status_1().await?;
    // Evaluate charger status or update application state here.
    let _ = status;
    Ok(())
}
