Teensy 3.5 and 3.6 Internal Temperature?

[Connor]

Hi,

I have tried to get the internal temperature from the Teensy 3.5 and 3.6, but I get an analogRead(44) gives me a result of 0. I am using the wrong pin?

adc->setAveraging(16);
adc->setResolution(16);
adc->analogRead(44)
Thanks

Yes wrong pin...

As pin 44 is a real IO pin, with a pad on the bottom of the chip. Also it does not have Analog...

I believe on this boards, Temp is on pin 70, VRef is on 71...

Looking again at the look up tables in analog.c I don't think I ass any that have Temp on 44?
T3.0, T3.1/2 and TLC -> 38
