Module lps22hb 

Sensor Driver for the LPS22HB MEMS nano pressure sensor using the I2C bus.

https://www.st.com/resource/en/datasheet/lps22hb.pdf

The LPS22HB is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which communicates through I2C or SPI from the sensing element to the application.

Driver Semantics

This driver exposes the LPS22HB’s pressure functionality via the [PressureDriver] HIL interface. It doesn’t support handling multiple concurrent pressure requests.

Usage

let lps22hb_i2c = static_init!(
    capsules::virtual_i2c::I2CDevice,
    capsules::virtual_i2c::I2CDevice::new(i2c_bus, 0x5C));
let lps22hb = static_init!(
    capsules::lps22hb::Lps22hb<'static>,
    capsules::lps22hb::Lps22hb::new(lps22hb_i2c,
        &mut capsules::lps22hb::BUFFER));
lps22hb_i2c.set_client(lps22hb);
