changing the hx.set_reference_unit() value in example.py doesn't do anything

See original GitHub issue

I’m working with a 3kg load cell and when I run example.py with hx.set_reference_unit(1) it outputs:

adding 2kg to the load cell changes the output to:

i used hx.set_reference_unit(673) since 1347126 / 2000 = 673 but the output does not change after running please help 😦

I’ll update README.md and example.py this weekend to make it clearer.

Meanwhile, in example.py your getting the raw value from HX711 using hx.read_long(). Comment that one and uncomment hx.get_weight(5).

So, change this:

# Prints the weight. Comment if you're debbuging the MSB and LSB issue.
# val = hx.get_weight(5)
val = hx.read_long()
print val

To this:

# Prints the weight. Comment if you're debbuging the MSB and LSB issue.
val = hx.get_weight(5)
# val = hx.read_long()
print val
