How to read CONFIG1

[dsicon]

chip = PIC16F1933
if i put the register name
CONFIG1
in a statement PBP3 is not happy and will not compile

i am trying to debug something and i want to examine a few bits, just want to print a byte or word to my serial LCD to ponder what may be going on

is there a way to read CONFIG1 ? in PBP3

(in the MEL programmer software mePROG the config looks as expected)

will post more in another thread about the issue i am chasing

You either set the configs in the inc file or in your code. If you are relying on something else then you can have trouble.

yes i know, i just want to read CONFIG1, is that not possible ?

Maybe you should read that link again.

If that's not what you want, you'll have to give more details.

Hi
i assume you mean the 4093 link above ? (the posts crossed at the same moment)
now i have read it, says it is only for 18F, i have 16F

what i was wanting was simply to inspect these 2 bits in CONFIG1 as i was having trouble with the mode functioning properly:
in CONFIG1 WDTE <4:3>
since one can access most any register in PBP by its name i was surprised that CONFIG1 was not available, perhaps there is some good reason

i imagine i could discover where it is in memory and looks that way (i assume it is a fixed location ?)

The CONFIGxx names are used within PBP and are listed in the include files.

The individual registers are used by Microchip and are described in the datasheet.

I suggest reading the register directly (check datasheet to see if readable). This will be much more efficient and easier to implement.

Unless the PIC has CFGS you cannot read the fuses (otherwise known as config registers). This appears to be a PIC18 only thing. Unless you have a suspect PIC or programmer they are what you last wrote to them.

BTW always a good idea to check for an errata if your PIC wont do as it's told.

thanks for that confirmation about not being able to read those registers in a 16F, too bad about that

i did read the errata and did not spot a related issue, peda is helping me on another thread here that is related to what started this
