Strange ADC behaviour

[ruijc]

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

[ruijc]

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.

[ruijc]

I still get behaviour no matter what i change...


except with Mister-e's code that works OK

Is it just a pbp version issue or is it something else ?

If it's a version problem...is there a way to get arround it ?

Hi, Ruijc

I just re-wrote your code ... works fine ( I'm only talking of the PIC point of view - do not talk about precision ...)

Try to write carefully ( and readably) ALL your config sequence ( I know ... ~ 50 lines ! )... and it will work !!!

Just a tip:

instead of :

" temp = (va1*/500)>> 2 "

try :

" temp = val*125
temp = temp.highbyte "
