CircuitPython interface for DYMO scales.
Project description
Introduction
CircuitPython interface for DYMO postage scales.
NOTE: This library will not work on embedded linux, only on microcontrollers.
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-dymoscaleTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-dymoscaleTo 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-dymoscaleUsage Example
Initialize the scale by passing it a data pin and a pin to toggle the units button:
# initialize the dymo scale
units_pin = digitalio.DigitalInOut(board.D3)
units_pin.switch_to_output()
dymo = adafruit_dymoscale.DYMOScale(board.D4, units_pin)Get the item’s weight from the scale:
reading = dymo.weight
print(reading.weight)Get the item’s units from the scale:
print(reading.units)To toggle between units (simulate a button press):
dymo.toggle_unit_button(switch_unit=True)To toggle the unit button, but preserve the unit displayed:
dymo.toggle_unit_button()Contributing
