My problem is solved. I have my timer0 with a 1:1-prescaler and no unwilling WDT-reset. But I haven't seen that I had also a problem of lack of intensity in my circuit, which provoked also a reset. So please excuse me for all! My training master, Samuel, is now very upset because you would think he was stupid. But he is clean in the story (except if we considered he could have helped me a little more for a so small problem... bad master! :-D ) Maxime Maxime has just forgot to tell you that last month, he already got this problem... bad trainee! :-( Sam -----Message d'origine----- De : pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]De la part de Dale Botkin Envoye : jeudi 29 aout 2002 15:04 A : PICLIST@MITVMA.MIT.EDU Objet : Re: [PIC]:problem with Watch-Dog On Thu, 29 Aug 2002, Samuel BOUQUET wrote: > Is it possible that the undesired WDT doesn't appear on the ICEPIC Emulator > but is here on the programed 16F872? Probably. Emulators often don't reproduce all of the correct hardware conditions, let alone the incorect ones.
