Old post but the old data sheet I believe had a wrong formula for calculating the excitation. Correct is AVDD = VBG(R1+R2)/R2 See here https://cdn.sparkfun.com/assets/f/5/5/b/c/SparkFun_HX711_Load_Cell.pdf
Can you just convert the parquet to a pandas dataframe and then use df.to_pickle?
Call your tare function in an interrupt that fires when the button is pressed.
See my other comment here [mV/V output on HX711](https://github.com/bogde/HX711/issues/208#issuecomment-890373362)
I think you can get mV/V like this: `mV/V = rawLSB / maxLSB * ADC_diff_ratio / ADCgain * 1000` where: `rawLSB` is the count value returned by the HX711 `maxLSB...

I derived the equation using a table in the TI data sheet. You probably want to keep everything as mV/V not voltage (V). If you have to convert to voltage,...

This is a numpy issue occuring in numpy\lib\nanfunctions.py https://github.com/numpy/numpy/blob/v1.26.0/numpy/lib/nanfunctions.py#L236-L361 Can suppress the warning by wrapping the code section causing the warning with a warning ignore statement.
