I have a Raspberry Pi Pico running an NB-IOT modem, which is powered by a battery and maintained using a solar panel. It sleeps for 6 hours, wakes up and reports the voltage read from the modem, and the internal temperature of the Pico. I am finding that the temperature is low. I read this post viewtopic.php?p=2117993&sid=ceaa6b95334 ... 383b8d6cd8 and see that the internal temperature is calculated using ADC_VREF, which is different each time. How do I change the equation for different voltages? Here are some results
Code:
