Project description
Introduction
Library for the DPS310 Precision Barometric Pressure Sensor
Dependencies
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
Installing from PyPI
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-dps310To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-dps310To install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-dps310Usage Example
import time
import board
import busio
import adafruit_dps310
i2c = busio.I2C(board.SCL, board.SDA)
dps310 = adafruit_dps310.DPS310(i2c)
while True:
print("Temperature = %.2f *C"%dps310.temperature)
print("Pressure = %.2f hPa"%dps310.pressure)
print("")
time.sleep(1.0)Caveat: by default the library initializes the IC with constant temperature and pressure measurements at 64Hz with 64 samples. It is not possible to change the IC’s mode, temperature_oversample_count or pressure_oversample_count on-the-fly so resetting the IC and operation parameteres is required. For instance, to set the mode to continuous pressure measurement at 1Hz with 2 samples:
dps310.reset()
dps310.pressure_oversample_count = adafruit_dps310.SampleCount.COUNT_2
dps310.pressure_rate = adafruit_dps310.Rate.RATE_1_HZ
dps310.mode = adafruit_dps310.Mode.CONT_PRESSURE
dps310.wait_pressure_ready()Contributing
