    are there any schematic diagrams for a programmer for the Atmel AT89S51?

    I googled for a little bit; then i decided that its too specific of a question; and im new to this area of electronics so i wouldn't know how to broaden it and keep it refined enough...

    I'm trying to make a 8 bit synthesizer...probably will take a while, but its one of those first time projects...but they take forever anyways!

    thanks,
    iRRVi

    Go to http://bit.kuas.edu.tw/~8051/ and scroll down to AT89C51 Programmer.

    Is there any particular reason you're using the AT89S51? The AVR core microcontrollers are much more popular with the hobbyist community so you'd probably have better luck with them.

    sorry; i wasnt specific enough:

    does just connecting the correct leads to the correct pins on a D-SUB connecter (i forget the name for the one on the computer) make a programmer for all ATmega's or others for that matter?

    Technically, yes, or at least any AVR device that supports In-System Programming (ISP), which I think all of them do. But, I'd take the time to do it right, as according to the previous webpage you risk ruining your parallel port, which can be a real bummer (when was the last time you saw a PCI parallel port card?).
