PIC500

I needed to program some AVR devices recently, for project to be described here later, so I needed programmer for this. Honestly speaking, I don't like AVRs at all and spending 40EUR on serious programmers on that seemed too much (I don't think that USBASP or its 4USD chinese clones are good progammers), and having another AVR in house wasn't attractive neither.
So I decided to program AVR from PIC, kind of interracial cooperation, which seemed to be acceptable for me for the time being.

In fact it was quite easy. I took sources from tuxgraphics and wrote new low-level layer fro PIC device. There were some platform dependant things in protocol layer sprinkled all over the shop, so I corrected it. I divided things into two main groups - protocol  layer and hardware layer, separated into two .c files, unlike original sources with many source files.

Hardware is quite simple - programmer is powered from target application, so level converters are not needed. There is no ESD protection on programming lines, just straight IO pins of PIC. User have to be careful, but I'm planning to use it a few times and then forget it, so no problems.

There is not much to say about it. It works with AVRStudio (on Windows) or avrdude (Windows / Linux), as fast as other AVR serial STK500 programmers.
