Honored ContributorTEMPDIODE reading low
I'm reading the temp diode on a stratix IV fpga, and it reading about 50C below what it should be. It is changing in regards to thermal heat and cooling, but it always seems about 50C too low....

Honored ContributorSorry, I was confused too. We are using an external ADC with a 12-bit resolution. That is why we are getting 0x414, and read -12C.
I'm still not sure why we are gettin 0x414 though. In the megafunction manual, table 4 shows a sign bit. Could this be screwing us up in the 12-bit read?
