Expand description

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);
