LM35DZ + Temp

[skimask]

It's not show corect.
I try the code below and work but the decimal change every 0.5C
How change to have resolution every 0.1C

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
