Hii Everyone,I'm unable to get correct values of proportional weight w.r.t the actual weight using HX711 module with a3kg load cell, can someone please tell me how to calibrate load cell and also how to get proper values?

First of all I do not have any similar hardware so I can not test it and tell you “do this”. And in our previous discussion I recommended to you another library because I am sure it is working because I know its maintainer.

How to integrate load cell of 3kg with nucleo f767zi ? Can some one help with drivers?

So maybe use search on Mbed web- Search | Mbed = HX711 This one seems promising - HX711 - Library for communication with the HX711 24-Bit A… | Mbed BR, Jan

Hx711 scale(PC_3,PF_3,128);

Second, why you have here the number 128?

@fermedicius

The loadcell that I’m using is of 3kg capacity but the major problem that I’m facing is that as I increase the values of known weights the proportional values are getting reset after certain weight( i, e some 750 grams).

Your values are not correctly set. Wrong gain or something liek that.

BR, Jan
