Strange ADC behaviour

[ruijc]

Thanks for the help

The code is correct like Mister-e posted because the reading values are 0.xx and with the /100 i would have just 0 !

Changed everything but i still get

porta.1 = 17
and
porta.0 = 0

changing each other i still get the same on lcd

.

out of curiosity, which version of PBP are you using? i've never ever used ADCIN in my program since over 5-6 years.

I may bet on some averaging... but i hate to bet on friday

My version is 2.47

But i will try a 2nd pic now and see...

Tryed a 2nd pic but same result...

it's not a pic failure

How better/worst it is if you dump the appended .HEX file in your PIC... don't change anything in the config fuses.. use it AS-IS

I just changed the MCLR off to on ( i was affraid i could get my pic locked ).

But it worked and both ports are 0.15V ... meaning...are reading both LM35

EDIT:
The first line of the LCD is not steady...i mean...i get VOLTAGE..0.15V and dLTAGE..0.15V ( blinking some times )

After the Line2 command, I found that I often had to add a space ahead the text, or the first character would get dropped. Some LCD's are too slow to change lines and display immediately. Apparently you need a delay, since it's effecting more than one character.
