Slow data readings about hx711_adc HOT 4 CLOSED

Hi!
There is no benefit to twist the dout and sck wires unless they are very long (these are digital signal wires).
The settling time with default settings and the HX711 in LOW RATE is 1.8 seconds. This is a result of the HX711 sample rate (HIGH or LOW) and the settings you have in the config.h file. See description in the config.h file:

Allowed values for "SAMPLES" is 1, 2, 4, 8, 16, 32, 64 or 128.
Higher value = improved filtering/smoothing of returned value, but longer setteling time and increased memory usage
Lower value = visa versa
The settling time can be calculated as follows:
Settling time = SAMPLES + IGN_HIGH_SAMPLE + IGN_LOW_SAMPLE / SPS
Example on calculating settling time using the values SAMPLES = 16, IGN_HIGH_SAMPLE = 1, IGN_LOW_SAMPLE = 1, and HX711 sample rate set to 10SPS:
(16+1+1)/10 = 1.8 seconds settling time.
Note that you can also overide (reducing) the number of samples in use at any time with the function: setSamplesInUse(samples).

Thank you so much for the response! What would be your recommendation with regards to the config.h in order to optimize for Accuracy & Speed? Is there a sweet spot for this or is it the 1.8sec?
Which wires would you twist between the load cell and HX711?

There is no general sweet spot really, it depends on your requirements and it will always be a compromice between speed vs accuracy.

Ok, thank you very much!
