Also, the pinouts were different since it was a different board. haha. But there were only a couple pins different, so it would be an easy fix.

I guess we just need someone to compile it at the command line of linux. I used to have a dual boot with linux and windows, but that computer crashed and took all the code with it. Each time I used Linux, before compiling things in linux, I used to have to type 3 random commands which made no sense to me. I don't remember what they were now, and there were several obscure changes to the default C build environment too. Some changes to "delay.c" that comes with linux, and other weird things. It took Fran all of a saturday to walk me through getting it ready. It's totally not repeatable by me.
I will put together a virtual machine and it will make everybody's life easier. It will take a day or 2 to setup and configure everything. I will include the firmware for the controller ready for anybody who wants to use it.

You can download VM Ware Player free for personal use. This is what I will use. I will use the default configuration so it is the most compatible between different computers.
