Product Number: MAX31855
Hi.
I am designing the hardware with the MAX31855NASA device and I am creating the code to read the temperature it measures with a microcontroller.
I'm running the tests without the thermocouple connected, and it's working correctly, meaning bit 0 (OC Fault) is set to 1.
Now, I've connected the T+ terminal (pin 3) to GND, and all the error bits (from 2 to 0) remain at 0, indicating no errors.
This doesn't seem to make sense.
The full value read is:
0x01501790:
And this is a picture of my hardware:
Any ideas?
Any comments are welcome.
Regards
