Thanks to MAL's Adventures in Electronics Blog at

http://circuitfun.wordpress.com/2012/01/02/arduino-mega-shield-template-in-eagle-improved/

for the Arduino shield blank design.

Here are two simple PCBs to allow an Arduino DUE to be plugged into a Sanguinololu in place of its ATMEGA chip. One is a shield for the Arduino that has a pin header for a 20-way ribbon cable. The other is a PCB that just has a header for the other end of the ribbon connected to a set of pins that pretend to be the Sanguinololu's ATMEGA chip.

The four Eagle files you want are:

due-adaptor.sch due-adaptor.brd due-adaptor-sanguinololu-end.sch due-adaptor-sanguinololu-end.brd

The DUE pinouts are:

{X, Y, Z, [E]} {Bed, Hot_end} -1 = not used

STEP_PINS {54, 60, 46, 26} DIRECTION_PINS {55, 61, 48, 28} ENABLE_PINS {38, -1, 62, -1} STOP_PINS {3, 14, 17} TEMP_SENSE_PINS {10, 9} // Analogue pin numbers HEAT_ON_PINS {8, 9}

The pins are intended to be as compatible as possible with the RAMPS board, while allowing things like the Arduino Ethernet shield to work as well.
