To simulate the HX711 24-bit ADC in Proteus, you typically need both the simulation model (to see the component in your schematic) and the firmware library (to write the code for your microcontroller). 1. Download Proteus Simulation Model
.LIB and .IDX files (or the .dll file depending on the version you downloaded).LIBRARY folder you found in Step 1.Without a dedicated simulation model, you cannot test your load cell circuit virtually. Hence, downloading a third-party becomes essential for: hx711 proteus library download
