How do I access the 12 bit ADC in the RP2040? the analogRead command results in values 0 - 1023 for A0, A1, ..... What are the designations for the 12 bit ADC connections and how do I read them? Is there an example code around to look at?

Try adding this line to your sketch:

analogReadResolution(12);

You are welcome. I'm glad you are now able to get the full resolution from the RP2040's ADC. Enjoy!
