Temperature always 500 using Max6675

Hi Sir,
I'm using the Max6675 to detect temperature, but always show 500, I was using onling configure tool, and changed temperature sensor, also I modified "pin.h", Max6675_SS according to my PCB, but it didn't work. Can you please help me and let me know where else need to be configured? thanks a lot.
the temperature always 500.

 I changed Temperature sensor

 I changed MAX6675_SS


  • You can not use temp_0 for a thermistor. You need a analog input that is not connected with more electronic like the 4.7K resistor.  Instead use the slave select pin for that, so Digital pin 58 from your screenshot.
  • Thanks so much, it works. :)
