just for the record what version of alldigital.pbp did you try ? there are a number of versions

First off, ADCON1 = whatever. Don't use it. It'll just screw things up.

is not right ,it just does not do what you erroneously thought it did as archangel says

ADCON1 is where you CHOOSE what your voltage references are & Trigger Select

and needs to set appropriately " rtfm "

Richard,
Problem is; None of this is in the manual, it's in the data sheet, and it takes some of us a while before we understand how to read it, and when we get frustrated, it's just harder. That's why I explained it the way I did, because Acronyms are always obvious . . . to the person who makes them. The rest of us, maybe not so much.

as tony discovered the wrong info in a thread can lead you astray , I don't think perpetuating error helps anyone but the right info is priceless

Hi,
Here's my view on this....
This sort of info can't be in the manual because then the manual would be the size of all the 8bit PIC datasheets combined.

It's up to the user to set the registers correctly for the application at hand, HOW to set them IS described in the manual, WHAT to set the TO is described in the datasheet for the particular PIC. Yes, it does take some time to learn what to look for in a datasheet but you're going to have to learn it.

The commands I chose were those that I found on this forum, but did not work.

Just because you find a piece of code where you see some_register = some_value ' Enable this, do that doesn't mean it'll work for you and your PIC. Take CMCOM for example, it's not uncommon that someone finds a piece of code, on this forum, where it says CMCON=7 ' Turn off comparators, uses that on a completely different PIC than the one for which the code was written and ultimately ends up in trouble. All because the comment said Turn off comparators - which it of course does on the PIC for which it was written. On some chips the registers are named differently, on others you need CMCON=15, on others you don't need to anything.

Where exactly did you find the reference to ADCON1=15?

Finally, just because you find pieces of code an a forum doesn't mean it's correct, working, debugged code ready to go. Most of the code posted here contains errors and problems - which is usually the reason for it being posted in the first place even though you're sometimes asked to troubleshoot code without even seeing it.
