Dust
annother new board [www.reprappro.com]
But its the same ARM processor as the Arduino Due, so its firmware [github.com] should be able to be ported esily to ramps-fd
I've given it a quick look but it would need some work. Specifically many files are missing (and I haven't seen docs on where to get them). Additionally, the pin handling is messed up, and it's non-trivial to change pins. The problem is that even though the code is designed to be build with Arduino, it doesn't use the standard Arduino pin functions. Instead it defines a board-specific pin functions, including a board-specific pin table, which only has a subset of all MCU pins. I didn't bother myself with it further. Reference: google for SamNonDuePin.h which is one of the missing files.
