bmp5xx

True-to-spec async I2C driver for the BMP580/BMP581/BMP585 barometric pressure sensors.

• no_std compatible, works without an allocator
• Widely compatible, generic over [embedded_hal_async] I2C traits
• 100% documentation coverage
• Based on Bosch Sensortec BMP581 datasheet, written by a human
• Fully tested on real hardware: compatible with Adafruit BMP580 and Adafruit BMP581 development boards
• Working examples in the repository

Features

• Normal, forced, and continuous mode measurements
• Configurable interrupts
• Out-of-range configuration
• Oversampling, IIR filtering

Usage

Getting started is easy:

// initialize the sensor

let mut bmp5 = Bmp5xx::new(i2c, Delay, 0x47);

bmp5.init().await.unwrap();



// new pressure measurement

let pressure = bmp5.meas_pres().await.unwrap();

Advanced operations:

// change oversampling rate

bmp5.osr_temp(Oversampling::X8);

bmp5.osr_pres(Oversampling::X128);



// set up interrupts

bmp5.int(Interrupt::default().enable(true)).await.unwrap();



// start continuous measurement

bmp5.start_continuous(true).await.unwrap();
