Hello !

Where can i find a hardware scheme to build a programmer that's support AT90s4414 or a AT90s8515 or the AT90s8535 ?

Thanks.

Hi,

There are lots of options. You could buy an AVR-ISP for $30, and not have to worry about any problems.

If you've got a real parallel port, you can build a simple parallel-port programmer. See http://freespace.virgin.net/sean... for information.

I've used the SP12 (with Ken's dongle - a signal buffer) located at "Programming a Spider's Brain" (do a Google search).
It has worked quite well after reading the dense instructions. Programmers need to learn to put the 'magic command line' for most important function of the program at the beginning of the documentation.
Since the most important function of an AVR programmer is burn code into chips, the documentation for the program should read...
"To burn an assembled file from WAVRASM.exe into an AVR, use the following statement on the DOS prompt:

C:\SP12 -wpf myfile.hex "

The file that has this information on using the program for what everyone who downloaded the program wants to use it for should be called:

ReadMe.txt

The ReadMe.txt file should not contain the latest version numbers and changes from the last file. It should contain a one sentence statement of what the program does followed by the OS under which it will work, followed by a short clear paragraph that explains how to do exactly what most people have downloaded the program to do. Version information should be in a file called: "version.txt".

I realize that I sound stupid, but I'm going crazy from downloading dozens of programs that are so poorly documented so as to be useless.

Anyway, SP12 works well as an AVR programmer for the IBM PC parallel port.

Good Luck.
