Analogue temperature input translation

Postby DaveTS on Mon Sep 13, 2021 4:55 pm

Hi there,

M142 with GPR-DI firmware.
Using an analogue temperature input for coolant temp sensor and want to set the translation table based off resistance. It is currently set to voltage, can this be changed? Or do I need to calculate the voltage at the pin based off the 1kOhm pull up to +5V?

Cheers,
Dave

Hi Dave,

What is the part number of the sensor? I may have a calibration for it that hasn't been published.
