CircuitPython driver for the HX711 load cell amplifer and ADC

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://circuitpython.org/libraries> or individual libraries can be installed using circup <https://github.com/adafruit/circup>.

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

.. code-block:: shell

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

.. code-block:: shell

circup install hx711

Or the following command to update an existing version:

.. code-block:: shell

circup update

Usage Example

.. code-block:: Python

import board
from hx711.hx711_gpio import HX711_GPIO
from digitalio import DigitalInOut

gpio_data = DigitalInOut(board.D5)
gpio_clk = DigitalInOut(board.D6)

hx = HX711_GPIO(gpio_data, gpio_clk)
