CircuitPython interface for DYMO postage scales.

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-dymoscale

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-dymoscale

To 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-dymoscale

Usage 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()
