Dumb programmers that just=20 consist of a non-programmed components and intelligent programmers that=20 have a microcontroller in the programmer to handle the programming process. The trouble for a newcomer these days is that dumb programmer designs=20 often rely on legacy ports (e.g. serial and paralell) that either don't=20 exist or aren't correctly implemented on many modern systems and=20 intelligent programmers often run into the catch 22 situation of how do=20 you program the microcontroller in the programmer. >can someone direct me a working programmer circuit with software setting. There are many designs but we really need to know which pic families you=20 will be working with and what ports your computer has first. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
