Just trust me > on this. After all, what option do you have? MCLR should not be left open, this is perfectly clear from both the datasheet, the programming documentation, and from the meaning of the pin. The fact that internal MCLR can cause problems is not clear from the obvious sources, so it seems a good idea to me to give that hint to the OP, or should JE have kept that to himself? The explanation for this problem is complex, and the link (to the microchip forum) can be found in earlier posts. I don't understand why you seem to critisise JE here. Is it for bidden to give a very important hint without also giving the (very long and complex) explanation (that is available elswhere, explained by probably the only person why realy understand it)? -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
