lps22hh 0.1.1

Raspberry Pi Pico Micropyhton library to interact with the ST LPS22HH Barometric pressure sensor

LPS22HH Pico Driver

Micropython library for the ST LPS22HH pressure sensor

Overview

The LPS22HH sensor is a high-resolution digital output pressure sensor manufactured by STMicroelectronics. This driver enables seamless integration of the LPS22HH sensor with the Raspberry Pi Pico.

Features

• Interface to communicate with the LPS22HH pressure sensor.
• Reading of pressure and temperature values
• Configuration of registers via dedicated functions
• Communication via SPI (I2C not implemented yet)
• Designed to be compatible with the Raspberry Pi Pico running on Micropython. Other boards not tested

Installation

pip install lps22hh

Getting Started

from machine import SPI, Pin
from lps22hh import Lps22hh

# Create a new SPI device, and assign the pins corresponding to your device
cs_pin = Pin(1, Pin.OUT)
spi = SPI(0, baudrate=1000000, firstbit=SPI.MSB, sck=Pin(2), mosi=Pin(3), miso=Pin(0))

# Create a new instance of the Lps22hh sensor
sensor = Lps22hh(spi, cs_pin)

# By default, the device is in power-down mode and the ODR need to be changed
# for the device to take continuous measurements
sensor.data_rate = 200

# The Block Data Update (BDU) is used to inhibit the update of the output
# registers until all output registers parts are read, to avoids reading values
# from different sample times
sensor.block_data_update = 1

while True:
    if sensor.new_pressure_data:
        print(sensor.pressure)

TODO

• FIFO functionalities
• Interrupts
• I2C, I3C communications
