MAXCLKnumber
Insert the CLK pin for the SPI communications (the 5 pin is used by default)
MAXCSnumber
Insert the CS pin for the SPI communications (the 4 pin is used by default)
MAXDOnumber
Insert the D0 pin for the SPI communications (the 3 pin is used by default)
UPDpulse
Node for updating the measurements
DONEpulse
Pulses 1 when a measurement has been done
TempReadnumber
Test to check if the hardware is working correctly. Gives 1 if the reads give a numeric value, or 0 if something is wrong with the thermocouple.
IntTempnumber
Displays the internal temperature of the thermocouple (in oC)
Tempnumber
Displays the temperature (in oC)
