MS56xx device drivers

no_std drivers for the TE Connectivity MS56xx family of barometric pressure sensors.

• Supports MS5607, MS5611, and MS5637 sensors
• I2C and SPI interfaces supported (SPI for MS5607/MS5611 only)
• Async and blocking APIs via embedded-hal traits
• Second-order temperature compensation
• CRC validation of calibration data

The MS5607 driver is actively used in several projects at https://github.com/aris-space and deployed on flight hardware.

Crates

• ms5607-rs - Driver for the MS5607 sensor
• ms5611-rs - Driver for the MS5611 sensor
• ms5637-rs - Driver for the MS5637 sensor

Supported Sensors

• MS5607-02BA03 - Datasheet: https://www.amsys-sensor.com/downloads/data/MS5607-02BA03-AMSYS-datasheet.pdf
• MS5611-01BA03 - Datasheet: https://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Data+Sheet%7FMS5611-01BA03%7FB3%7Fpdf%7FEnglish%7FENG_DS_MS5611-01BA03_B3.pdf
• MS5637-02BA03 - I2C only, extended oversampling range (256-8192)

All sensors use a similar communication protocol but differ in their temperature compensation algorithms and features.

Usage Examples

Using the MS5607 crate

use ms5607_rs::{Ms5607, Oversampling};

// I2C (CSB pin high = address 0x76)
let mut sensor = Ms5607::new_i2c(i2c, true);

// Or SPI
let mut sensor = Ms5607::new_spi(spi);

// Async API
sensor.init(&mut delay).await?;
let measurement = sensor.measure(Oversampling::Osr2048, &mut delay).await?;

// Blocking API
sensor.init_blocking(&mut delay)?;
let measurement = sensor.measure_blocking(Oversampling::Osr2048, &mut delay)?;

Using the MS5611 crate

use ms5611_rs::{Ms5611, Oversampling};

// Same API as MS5607
let mut sensor = Ms5611::new_i2c(i2c, true);
sensor.init(&mut delay).await?;
let measurement = sensor.measure(Oversampling::Osr4096, &mut delay).await?;

Using the MS5637 crate

use ms5637_rs::{Ms5637, Oversampling};

// I2C only, fixed address 0x76
let mut sensor = Ms5637::new_i2c(i2c);
sensor.init(&mut delay).await?;
// Extended oversampling range
let measurement = sensor.measure(Oversampling::Osr8192, &mut delay).await?;
