Hi,

Great job, Thanks fellas,
So is it possible to have axis output (STEP/DIR) on arduino mega output ? for example port 0 pin 24 for X DIR and port 0 pin 25 for STEP ? so we can have a modbus breakout ?

Thanks

Awesome job! Just thought i would let you know I got this installed on a Teensy 3.2 and have used the USB for the interface. The goal is to use this as a pendant.

Hello. I ask you for help. I have a board arduino uno. I'm trying to flash it in the instructions, but it does not work.Gives an error message:

 -Arduino: 1.6.3 (Windows XP), Board: "Arduino Uno"
Build options changed, rebuilding all
CRC16.cpp:16:22: fatal error: WProgram.h: No such file or directory
 #include "WProgram.h"
compilation terminated.
Error compiling.
  This report would have more information with
  "Show verbose output during compilation"
  enabled in File > Preferences.

Tell me please what am I doing wrong? ???
Sorry for my English. Thank you in advance

I have been trying to make Shilling's code work for arduino due without success; the sketch uploaded successfully and the serial led's blinking, but no input/outputs responses between master slave.  On Uno the code works fine.  Has anyone tried to use arduino due with this code?  What could make it not working for due?

Bolded should be changed with Arduino.h if you use newer version of compiler.
