 [`Bmp390`](https://docs.rs/bmp390/latest/bmp390/struct.Bmp390.html) is a driver for the BMP390 sensor. It provides methods to read the temperature and pressure from the sensor over [I2C](https://en.wikipedia.org/wiki/I%C2%B2C). It is built on top of the [`embedded_hal_async::i2c`](https://docs.rs/embedded-hal-async/latest/embedded_hal_async/i2c/index.html) traits to be compatible with a wide range of embedded platforms. Measurements utilize the [`uom`](https://docs.rs/uom/latest/uom/) crate to provide automatic, type-safe, and zero-cost units of measurement for [`Measurement`](https://docs.rs/bmp390/latest/bmp390/struct.Measurement.html).
 
+Synchronous and asynchronous interfaces are available. The synchronous interface is built on top of the [`embedded-hal`](https://docs.rs/embedded-hal/latest/embedded_hal/) traits, while the asynchronous interface is built on top of the [`embedded-hal-async`](https://docs.rs/embedded-hal-async/latest/embedded_hal_async/) traits. The default features include the *asynchronous* interface, but the synchronous [`sync::Bmp390`](https://docs.rs/bmp390/latest/bmp390/sync/struct.Bmp390.html) one can be enabled with the `sync` feature.

 ## Datasheet
 The [BMP390 Datasheet](https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmp390-ds002.pdf) contains detailed information about the sensor's features, electrical characteristics, and registers. This package implements the functionality described in the datasheet and references the relevant sections in the documentation.
