Thanks for the help .. the problem was indeed in the fuses. I was using the Microchip templates and the _LVP_ was ON instead of OFF. Since i don't use LVP (yet) i turned it off and now the reset works properly.=20 Arno Quoting Jai Dhar >>That should be ok - same setup as I have. Did you set your fuses right while programming? I believe that MCLR can be programmed as a reset or as something else... not too sure. But check your programming software. > I have a weird problem with my pic16f877. On power-up everything runs fine, but as soon as i reset the board doesn't seem to do anything anymore. MCLR is connected to a 10k pull-up and a resetbutton which is tied to the ground, so that should work fine. As far as i know, on reset the program should start at 0x000 .. or am i wrong ? =20 =20 -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
