Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

When I was playing around with Thonny before finding MMBASIC, they had a way of using the internal temperature sensor. I know it was reading the CPU temperature... but I still found it handy.

I didn't see any mention of that in the manual (I may have missed it) but is it possible to do?

Did we have something like this?

from picozero import pico_temp_sensor
from time import sleep

while True:
print(pico_temp_sensor.temp)
sleep(0.1)

Thanks,
Jerry

Yup... that worked... 35.46 I'll have to do the math to convert... but that's the easy part.

Thank you PhenixRising :-)

I had a RP2350 DIL module, running overclocked @378MHz for several days and it somehow found its way between pages of a closed book. The module was very warm to the touch but the reported pin(temp) was only 51°

Wait... 51C is 123.8F (Yeah, that's a bit warm)
