Reprap32 -- 32Bit Reprap control based on AVR32

This is a Reprap 32bit control board based upon AVR32 (AT32UC3B0256) CPU.
It is a functional replacement for the Gen4 Aruduino mega and it's motherboard. The code has been ported to AVR32 GCC from Makerbot G3 branch (the V2 code),

Status: As of OCT 8th, 2011
The atmel CDC driver for USB is now running on the hardware with terminal emulators. The next step is to port it into tha main REPRAP32 application. I will probably try a USB branch on the main git repository. I have not yet published a branch and need to learn how to do it correctly.

I have some bare stepstick PCBs in hand now. So I can build a full stepstick based prusia with USB reprap32 for my daughter at college.

I checked the loading of the 64us stepper timer interrupt to see how much cpu time the steppers are using. I found 22% nominal and 36% worst case. This leaves 53 DMips of cpu still available.


I was able to drive the Gen3 stepper drivers on my Prusa with no issues. Just a cable slide fro
