LM35DZ + Temp

[savnik]

Ok, forget all the math and displaying for the moment...

What is the output on the LCD if you only read the A/D converter with the LM35DZ connected... no averaging, no multiple samples, no nothing, just one saple, one display...pause, one sample, one display, and so on...
Get a good reading that seems to make sense, then we can work on displaying it correctly...

The output on the LCD is 44-46 (Vin = 44~46)
The temperature is about 22C in room

I change to :

ADCloop:

    ADCIN 2,Vin
    Pause 200 
    Vin=(Vin* 10)/2
    Lcdout $fe, 1
    LCDOUT $FE,2
    Lcdout "Temp=",DEC (Vin DIG 2),DEC (Vin DIG 1),".",DEC (Vin dig 0),"C"			          
    goto ADCLoop

and believe is right
The LCD now show : Temp=22.5C
