Would using the ADS1015 mean the voltage offset would not be a problem? I still see the resistance difference using the ADS1015 on both the PI4 and an Arduino.
I've measured the circuit four different ways (ADC differential Pi, ADS1015, ADC onboard PIco, and external voltmeter) all of them show differing voltages depending on the voltage direction on both the GPIO to GPIO circuit and the H-bridge circuit, including when I used a waveshare to activate the transistor pins. Would you expect all of them to have an offset problem, or does that mean it's more likely to be an issue with the PI/microcontroller?
