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.

i see no schematic anywhere and post 1 says a lm35, a pullup for a lm35 is not warranted.
this has turned into a pointless exercise in guesswork.

this won't work properly with those readings either

670 */ 1250 = 3271 and would display as 27.1 deg with following code

temperature= temp */ quanta  ; this result is now 4 digits




lcdout $FE, 2, "Temp ",dec2 (temperature/10),".", dec1 (temperature/10),"C"

its just so wrong i give up
