io.h folder/files

Trying to flash a modified parameter file for a 3D printer with the RADDS DUE based system. Using Repetier and/or Marlin. Get the same result. Compiling is terminated because there is no "io.h" file/folder. Both Repetier and Marlin through Arduino IDE have a "fastio.h". Problem doesn't exist with the RAMPS/MEGA 2560 combination.

Not being able to reflash the DUE makes it useless as a one shot deal.

Any suggestions?



Io.h is an avr-only thing. Due normal io may be fast enough that you don’t need a fast io, but it sounds like you’ll need to find a version of the marlin/whatever firmware that was designed for due.
