Library for the DPS310 Precision Barometric Pressure Sensor
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-dps310
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-dps310
To install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .venv source .venv/bin/activate pip3 install adafruit-circuitpython-dps310
Installing to a connected CircuitPython Device¶
Some devices, eg. the QT-PY, are very limited in memory. The DPS310 library contains two variants - basic and advanced - which give different levels of functionality.
Installing the DPS310 library could have the following outcomes:
It installs successfully and your code runs successfully. Woo-hoo! Continue with your amazing project.
It installs successfully and your code fails to run with a memory allocation error. Try one of the following:
code.pyis large, especially if it has lots of comments, you can shrink it into a
.mpyfile instead. See the Adafruit Learn Guide on shrinking your code.
Only use the basic DPS310 implementation, and remove the following file:
<CIRCUITPY>/lib/adafruit_dps310/advanced.mpywhere <CIRCUITPY> is the mounted location of your device. Make sure that your code only uses the basic implementation.
import time import board from adafruit_dps310.basic import DPS310 i2c = board.I2C() # uses board.SCL and board.SDA dps310 = DPS310(i2c) while True: print("Temperature = %.2f *C"%dps310.temperature) print("Pressure = %.2f hPa"%dps310.pressure) print("") time.sleep(1.0)
Library extensive features might not be compatible with memory limited boards. For these kind of
boards you need to use the
adafruit_dps310/basic.mpy, the file needs to be in the
format in order to fit in memory.
For boards with more memory available you could use the code present
adafruit_dps310/advanced.py. For usage refer to
API documentation for this library can be found on Read the Docs.
