I'm just playing around and tried to read the internal temperature sensor ("core temp"), but I can't get it to work (in serial console).
When I try setting it up I get an error saying that the pin doesn't have ADC capabilities.
The example I started with is found here: https://github.com/raspberrypi/pico-mic ... erature.py (as well as in some docs).
But I've also looked at RP2350 datasheet to confirm that it's the right channel, etc.
Here's some examples of what I've tried (removed Traceback for brevity):ADC.CORE_TEMP does return 4
I can setup and read from other ADCsAlso tried onIs there a trick I'm missing, is it a bug/not yet supported??
