Y-axis test firmware operational

After a delightful chat with Bogdan this morning about the PIC32's MIPS core processor, I was able to get the y-axis test firmware working.  Bogdan has done a lot of work with the PIC32 and is very generous with his knowledge.  A few hours later, I had the y-axis responding to the limits switches.

Right now with sampling from the limits switches in the same loop that runs the stepper I'm getting 15 mm/sec.  On its own the stepper can do about 52 mm/sec.  I suspect that the speed of the axis will be getting a lot closer to that upper limit once I get the limits switches into an interrupt loop.  :-)
