I have one of the HX711 ADC devices that I want to use for a weighing application. I've fitted it to a breadboard and used demo firmware to poll the chip for readings. The behaviour is as follows: The ADC uses a PNP transistor to control the voltage that excites the bridge. The Base output from the ADC is right at VSUP, so no voltage goes to the bridge.
Has anyone got success? failure? experience? with this device? I'm confused as to whether the communications from the MCU enable the base to move below VSUP allowing the bridge to be excited.
