Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...
************************************************** ***********************
IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Is this specific for 10 bit ADC, or should it be there for 8 bit conversion as well?
And how? -CMON0 something?
Hm, the example programs that I have (for 16F877A) do not have such an instruction, does that PIC not need it?
ADCON0.7 = 1 seems to have have cured the problem, thanks guys.

have a look to datasheet ... Comparator section !!!
some pins share the comparator and ADC functions ... you HAVE to verify which function is deactivated and which is to activate. ( one at a time ... )Hm, the example programs that I have (for 16F877A) do not have such an instruction, does that PIC not need it?
Depends on the chip used - and the ports used ...
Full config done = NO suprise ...ADCON0.7 = 1 seems to have have cured the problem, thanks guys.
sometimes, the pic defaults @ reset are the ones you want ... sometimes not. so you have to verify everything with the pic Datasheet !!!

Done that, but didn't understand it (new to this stuff).
seems to be accepted by PBP and the chip (still) works.Code:CMCON0 = %00000000

Boooooooooooooo ....the chip is really gentle with you ...
look a bit closer at the drawings and the corresponding config @ $8 p 53 ...

I said that I don't understand this kind of data sheet...
Well, I think it says that .....000 only turnes the comp output off, but ....111 turnes the comp off as well. It doesn't matter much for this project, but my first project is battery operated and saving some current is welcome.
I guess it's nice to have a comparator integrated, but right now I would need an OP-amp instead!

I do promise you lots of fun ...I said that I don't understand this kind of data sheet...

Swedish hot nights ... I believed it was a bit different

Yes, I have had some interesting output signals on outputs that were not specified in the program!sometimes, the pic defaults @ reset are the ones you want ... sometimes not. so you have to verify everything with the pic Datasheet !!!
