Xtal as close as possible to the Pic, capacitors form each pin of the xtal to gnd. thc capacitors also close to pic and xtal. By following th PIC-List I saw/read many questions you wrote. Your questions give me the Idea, that you eventually don4t now about the datasheet4s available from the microchip web-site. They have also a lot of application-notes where you may wish to have a look at. There you4ll find a lot of comprehensive stuff. Kind regards Stefan
