Hi, I have downloaded the latest version of the library and I could reproduce your error.
To fix it you need to download the version of the library that was available back then when I created this project (around July 2017).
You can get HX711.h and HX711.cpp here (bogde/HX711 commit e80de1c): https://github.com/bogde/HX711/tree/e80de1c07e990e07627ec215eec9e1efabf281ee
Hi, I was trying to test out your code as it sounds pretty impressive. whenever I try to complie for an Arduino Nano i am getting errors compiling. I have copied HX711ext.h and HX711.cpp into the HX711 library but i am getting the following errors:

Can you confirm which library you were referencing as I am wondering if I am trying to use a different version?
Thanks
