This is a great PID controller, however I am having some trouble with interfacing a NTC thermistor. Firstly, I do not have the MAX31855 chip, and do not plan to connect a thermocouple, do I need that for the system to function? Secondly, what input is A6 on the arduino expecting from the thermistor? I presume 0-5 volts?
So I worked out that I need to add the values for the thermistor coefficent. Can you please elaborate on which values are being use for T0 and R0 are those at zero degree’s or at 25 degree’s C? Does OSPID calculate the beta factor from those values?
