I'm currently building a motor test setup using the popular HX711 amplifier from Sparkfun and running it with an Arduino. I have built my version off of the popular "Model Rocket Engine Dynamometer" code from Nick Cinquino.
I am having a hard time getting my load cell to read a constant "zero". The data rate is set to 80Hz. I have attempted to adjust the calibration factor and have it close. I know that the data will vary each time the "scale.get_units(),2;" line is read, but my data is jumping around like crazy.
Is this amount of bouncing normal for the HX711 amplifier?
How do people use these to get a constant reading when using it as a static scale?
