How about non-gui users? What's the conversion formula? To be clear, I am using the excellent FB driver by malcolm2073 on linux.
I believe I have a MCP9701A and the datasheet says it outputs 200mV to 3V for the temperature range of -40°C to 125°C. It goes on to say it outputs 19.5mV/°C and 400mV is 0°C.
But what I am getting are negative integer values from the FB. It is probably 60-70 in here and I'm seeing -70 to -80.
BTW I have similar questions for the Photosensor. The datasheet is not currently available but I'm getting what looks like 0 for darkness and 20 for room lighting. Not sure what the actual range and values should be though.
