HX711 Qwiic version comms protocol

Hi, I am using the Soldered HX711 - Qwiic version - in a project that specified a more generic type of HX711 like this Amazon.com: DIYmall 2pcs Hx711 Weight Weighing Load Cell Conversion Module Sensors Ad Module for Arduino Microcontroller : Industrial & Scientific

Unfortunately, I’m not getting the I2C comms to work and communicate with the ESP32 using the project software designed for the generic HX711. Does the Soldered version communicate in the same way as the generic version, or need a specific library? I see that it is addressable, unlike the generic HX711.

Hi @george2

The module in your link is not an I2C module and therefore cannot be used with any I2C HX711 libraries like the Soldered one. You can find our library for your Soldered module here.
You will want to change the project code to use our library instead of the generic bit-banging one.
For the one you linked, simple pin bit-banging is used, I found this library as an example.
