MAX 10 Modular ADC TSD

Hey,

I followed instruction from the example project on this page: https://cloud.altera.com/devstore/platform/16.0.0/nios-ii-on-die-temperature-sensor-design-example/

trying to read on-die temperature.

Whatever settings I try to change (including the original) I keeps reading only slot# 1 out of the 64 of the example, all the others are zeros.

Even that first one gives me irrational -15/16/17 Celsius degrees (code 3754/6/9).

I'm using model 10M50DAF256I7G.

I found vary little on this on the web.

EDIT 1:

So the example project does work on the development kit (gives reasonable temperature), with model 10M50DAF484C6GES.

The question remains why model 10M50DAF256I7G returns unreasonable temperature.

EDIT 2:

I tried with another board with 10M50DAF256I7G and it returns even weirder values at around 3800's code.

EDIT 3:

With the ADC toolkit I can see changes that makes sense, for example when I try to change the temperature by touching it, and it happens in both models, and with all three boards.

So I suspect different models return different codes, although it I can't find any references about it and it certainly doesn't say it in the MAX 10 ADC datasheet. Anyone here have a stand about it?

Thanks,

Eyar
