    no, no. The problem why is the ADC reading high is the LM335 wiring. Cobuccit has wired a "pullup" resistor to LM335 from 5V and this shifting the output voltage to 3V at 30degC.

    My ADC settings on 16F690 is correct, I don't use settings for 16F88 on 16F690 of course.
    Anyway, I tried to figure out what's wrong with Cobuccit's setup and then I look at web and find the most popular LM335 wiring and then I got it. He has probably wired the sensor like this and that's the problem in cooperation with his posted code.
