Issue with HX711 reading

[duckredbeard]

I am getting the following error when running my code. I have a functioning version of this script, but this one is edited to include more LEDs and different values for triggering the LEDs. On this version, I am erroring on line 57 (which is hx.set_reading_format("MSB", "MSB"))with this:

attributeerror 'hx711' object has no attribute 'set_reading_format'
