Hi,
I have a PC104 486/66 MHz along with a Smart 518 A/D Temperature
measurement board made by Sensoray. The OS is QNX. For weeks now I have
been to trying to make the 518 work and give me temperatures through the
thermistors connected to a terminal board (also made by Sensoray).
I am able to perform simple tasks like reading the board, firmware nos,
and even reading the temperature on a small sensor that is inbuilt on
the board. But I cannot get anything from the thermistors. I keep on
getting 0 as the value read.
I can see the thermistor being pulsed on the oscilloscope and the
voltage level changes with change in temperature, but the board still
gives me 0.
Has anyone tried to work with this card before?..or is there some other
card that can be tried instead of the 518, which is meant esp for
temperatute sensing?
Thanks
Anup.
